| − | ===Setting Files===
| + | Although this page is long, building is generally quite simple. See the BUILDING.txt file in the distribution itself for simplified instructions. |
| | | | |
| − | Unlike binary distributions, OpenSimulator source distributions are delivered without default configuration files, i.e, '''OpenSim.ini''' and '''StandaloneCommon.ini'''. Therefore you'll need to create them by yourself. Look carefully at [[Configuration]] page not to suffer from the errors like ''"APPLICATION EXCEPTION DETECTED: System.UnhandledExceptionEventArgs Exception: System.Exception: Configuration file is missing the [SimulationDataStore] section"''(= missing "OpenSim.ini") or ''"Error loading plugin from OpenSim.Services.FriendsService.dll, exception System.Exception: No StorageProvider configured"''(= missing "*Common.ini").
| + | == Version 0.9.3.0 and above == |
| | + | Microsoft stopped the development of .Net Framework and Mono, replacing them by new dotnet |
| | + | This is a significant breaking change that we try to follow on 0.9.3.0. |

| − | The easiest platform to get running on the Linux side is Ubuntu 32bit. This is what most of the developers running Linux use. If you are looking for the quick path, start [[#Ubuntu|there]].
| + | get or update source from git |

| | + | To building under Windows, the following is required: |
| | | | |
| − | OpenSim requires either the .Net Framework version 3.51, or Mono 2.4.3 or newer. It supports the following compilers:

| − | Additional note: It is possible to develop with Visual Studio 2010 - C# Express with the following tweaks:
| |
| | | | |
| − | #In the top-level directory, run the '<tt>runprebuild.bat</tt>' file. This will create a VS2008 solution file.
| + | Configure, See [[Configuration]]. |
| − | #Open the VS2008 solution file in VS 2010 Express and run the conversion wizard to crease a VS2010 solution file.
| + | |
| − | #In the solution explorer of the resulting project, right click on each project (there are 91) and select properties. Under the Application tab, set the Target framework to .NET Framework 3.5.
| + | |
| − | #In the solution explorer, under the OpenSim project select "app.config".
| + | |
| − | #Copy the contents of bin\OpenSim.exe.config into the app.config file
| + | |
| | | | |
| − | === Building ===
| |
| | | | |
| − | *In the top-level directory, run the '<tt>runprebuild.bat</tt>' file. This will create a VS2008 solution file, a nant build file and a '<tt>compile.bat</tt>' file.
| + | Now just run OpenSim.exe from the bin folder, and set up the region. |

| | | | |
| − | Copy the <tt>bin/OpenSim.ini.example</tt> file to <tt>bin/OpenSim.ini</tt> before making any changes.
| |
| | | | |
| − | Assuming you initially want to create an Opensim Standalone setup, the example Opensim.ini already has the appropriate [Architecture] setting for that in place referring to an include file at <tt>bin/config-include/StandaloneCommon.ini.example</tt>.
| + | Create the project files, run: |
| | | | |
| − | Copy the <tt>bin/config-include/StandaloneCommon.ini.example</tt> file to <tt>bin/config-include/StandaloneCommon.ini</tt> before making any changes to that too. A cache is recommended to make Opensim run in a more stable and efficient manner. Choose a cache as described in <tt>bin/config-include/StandaloneCommon.ini</tt>.
| |
| − |
| |
| − | Double-click on the <tt>OpenSim.exe</tt> executable file in the <tt>bin</tt> directory. This will start up OpenSim in standalone mode.
| |
| − |
| |
| − | The debugger in VS2008 C# may be used to step through the code. For those that use a Cygwin shell, you may find that one or more dll's have permissions that cause problems running. Most find that a "<tt>chmod 777 *</tt>" from the <tt>bin</tt> directory solves this.

| − | '''''Windows Vista'''''
| |
| − |
| |
| − | Some people have reported that to run on Windows Vista, you must first disable Windows Firewall. Under the new "Start" button of Vista, select "Control panel". Then double-click "Windows Firewall". In the window that pops up, on the left column, select "Turn Windows Firewall on or off". You will have to give permission for this to run, then select the option "Off (not recommended)". Click "OK" and exit from the Windows Firewall window.
| |
| − |
| |
| − | If you have McAfee SecurityCenter, see the description below.
| |
| − |
| |
| − | Once all the security features are disabled, right click on <tt>OpenSim.exe</tt> and select "Run as administrator". This will pop up a window asking permission, select "Allow". Your OpenSim server should run in a DOS-like window and accept connections.
| |
| − |
| |
| − | '''''McAfee Security'''''
| |
| − |
| |
| − | McAfee Security does not allow applications to listen on ports not explicitly specified. You have two options: 1) disable firewall protection all together, 2) enable <tt>OpenSim.exe</tt> to be able to open ports.
| |
| − |
| |
| − | ''Disable firewall''
| |
| − |
| |
| − | Open McAfee SecurityCenter. Select "Internet & Network". In the lower left corner is a small link to "Configure...". Select this. In the right side of the window, select the bar that says "Firewall protection is enabled". Here you can select "Off".
| |
| − |
| |
| − | ''Enable <tt>OpenSim.exe</tt> to open ports''
| |
| − |
| |
| − | Open McAfee SecurityCenter. Select "Internet & Network". In the lower left corner is a small link to "Configure...". Select this. In the right side of the window, select the bar that says "Firewall protection is enabled". Select the "Advanced..." button. This will pop up a new window.
| |
| − |
| |
| − | In the new window, on the left side, select "Program Permissions." In the middle on the right side of the window, select the "Add Allowed Program" button. Use the browser that pops up to find the OpenSim executable and select it.

| |
| − | === Mac OS X 10.5 and later, Intel ===
| |
| − |
| |
| − | You might find it work for your environment (OS X 10.5.7, Intel):
| |
| − |
| |
| − | * make sure you have X11 installed
| |
| − | * grab the Apple Dev Tools from [http://developer.apple.com/]
| |
| − | * install Mono Framework 2.4 from [http://www.go-mono.com/mono-downloads/download.html]
| |
| − | * Recent versions of Mono/Nant may require an adjustment to PkgConfig. And in Terminal or X11 edit the .profile file and add the following line:
| |
| − | export PKG_CONFIG_PATH="/Library/Frameworks/Mono.framework/Versions/Current/lib/pkgconfig/:${PKG_CONFIG_PATH}"
| |
| − | * Get OpenSim source:
| |
| − | * Compile OpenSim:
| |
| − | cd opensim
| |
| − | ./runprebuild.sh
| |
| − | nant
| |
| − |
| |
| − | You might find it work for your environment (OS X 10.5.7 and 10.6, Intel) on (8/9/09):
| |
| − |
| |
| − | * make sure you have X11 installed (installed by default on 10.5 and 10.6)
| |
| − | * Very important to grab the latest Apple Dev Tools (3.2.1 on 8/9/09) (from [http://developer.apple.com/] - You will need a developer account, it is free.
| |
| − | * install Mono Framework 2.6.x from [http://www.go-mono.com/mono-downloads/download.html] ''Or perhaps the latest stable release.''
| |
| − | ''Mono includes nant, so it should not be necessary to build nant with MacPorts, but others have done so and left these intructions:''
| |
| − | * install Mac Ports from [http://www.macports.org/]
| |
| − | * Mac Ports should update its packages on install, but to be safe, type the following at the Terminal:
| |
| − | sudo port -v selfupdate
| |
| − | * Use mac ports to install nant. (This should pull in everything you need. I think this will also try to install mono, but since I already had it installed, that errored on me. Don't worry about it though, it should install everything else you need.) At the Terminal type:
| |
| − | sudo port install nant
| |
| − |
| |
| − | * Get OpenSim source. I downloaded 0.6.6 from [http://opensimulator.org/wiki/Download]
| |
| − | * Uncompress the download.
| |
| − | * Compile OpenSim:
| |
| − | cd opensim
| |
| − | ./runprebuild.sh
| |
| − | nant
| |
| − |
| |
| − | *Then of course the issue with the 0.6.6 release.
| |
| − | This release had some bugs with default automatic configuration on the first startup of OpenSim.exe. bin/Regions/default.xml (region configuration file) is not automatically created in the main directory. Therefore, you must manually create this file. Here is an example.
| |
| − | <pre>
| |
| − | <Root>
| |
| − | <Config sim_UUID="UUID" sim_name="NAME" sim_location_x="1000" sim_location_y="1000"
| |
| − | internal_ip_address="IP_ADDRESS_OF_SERVER" internal_ip_port="9000" allow_alternate_ports="false"
| |
| − | external_host_name="DNS_NAME_OF_SERVER" master_avatar_uuid="00000000-0000-0000-0000-000000000000"
| |
| − | estate_covanant_uuid="00000000-0000-0000-0000-000000000000" master_avatar_first="FIRST_NAME"
| |
| − | master_avatar_last="SECOND_NAME" master_avatar_pass="PASSWORD" />
| |
| − | </Root>
| |
| − | </pre>
| |
| − | You must change UUID, NAME, IP_ADDRESS_OF_SERVER, DNS_NAME_OF_SERVER, FIRST_NAME, SECOND_NAME and PASSWORD to your own values.
| |
| − | (I noticed than IP_ADDRESS_OF_SERVER should be set to real IP not to 127.0.0.1)
| |
| − |
| |
| − | '''Summary''':
| |
| − |
| |
| − | *Run OpenSim0.6.6Setup.exe and install OpenSim in Windows
| |
| − | *Run OpenSim.exe and enter default values - record them!
| |
| − | *Shutdown simulator (command: shutdown)
| |
| − | *Create default.xml with copy of above
| |
| − | *Change values in default.xml with recoded values
| |
| − | *Be sure default.xml be in main directory (same with OpenSim.ini)
| |
| − | *Run again OpenSim.exe
| |
| − | *Connect with viewer

| |
| − | === Mac OS X 10.4/10.5 on PowerPC ===
| |
| − | OpenSim can run on PowerPC Macs (such as G4, G5). These instructions were tested on 10.5.8. Note that two libraries must also be built from source. Caveat: the OpenSim app was only briefly tested in self-contained mode. There may well be issues with this build. Feel free to note any issues you find below (or in a new wiki page? discussion?).
| |
| − |
| |
| − | Unfortunately, the OpenSim version used here must be compiled on one version of Mono (2.6.7) and run on another (2.8.2). This means either upgrading Mono after the build, or having both versions installed and accessing the older version when you want to build. These instructions let you have both versions installed.
| |
| − |
| |
| − | * Install Xcode 3.1.4 Developer Tools from from http://developer.apple.com/. You must have a free Apple developer account to access the downloads. 3.1.4 was the last PowerPC Xcode.
| |
| − |
| |
| − | * (10.4 only) Install X11 from the Optional Install (or see if it's a Customize option when you install Xcode). 10.5 gets X11 by default (''from OS X or dev tools?'').
| |
| − | * Install Mono 2.6.7 PowerPC Framework from here: http://www.go-mono.com/mono-downloads/download.html (binary OS X Framework, no need to build from source)
| |
| − | * Then install Mono 2.8.2 PowerPC framework. For these instructions to work, you must first install 2.6.7, THEN 2.8.2. (The old framework is not deleted, but "Current" symlinks are updated).
| |
| − | * Download OpenSim 0.7.0.2 source tarball: http://dist.opensimulator.org/opensim-0.7.0.2-source.tar.gz Expand to a suitable folder for development and running.
| |
| − | ** Feel free to try a newer version of OpenSim (the repository is on git now).
| |
| − | ** If you used a newer OpenSim version, check BUILDING.txt for any changes to build instructions (we fall under "Linux")
| |
| − | * Edit or create .profile or .bash_profile in your OS X home folder, with the following lines:
| |
| − | # remember real PATH
| |
| − | export OSIM_HACK_ORIG_PATH=$PATH
| |
| − |
| |
| − | # normal path for running OpenSim
| |
| − | export PATH=$PATH:/Library/Frameworks/Mono.framework/Versions/Current/bin:/usr/local/mysql/bin
| |
| − |
| |
| − | # Just for nant:
| |
| − | export PKG_CONFIG_PATH=/Library/Frameworks/Mono.framework/Versions/2.6.7/lib/pkgconfig
| |
| − | alias oldpath="export PATH=$OSIM_HACK_ORIG_PATH:/Library/Frameworks/Mono.framework/Versions/2.6.7/bin"
| |
| − |
| |
| − | * Open a new Terminal window, and cd to your uncompressed OpenSim source folder (shortcut: type "cd " then drag the folder to the Terminal window). The enter these commands:
| |
| − | oldpath
| |
| | ./runprebuild.sh | | ./runprebuild.sh |
| − | nant
| |
| | | | |
| − | * nant should take around 10 minutes to compile your OpenSim. If you get through that without errors, you're halfway there! (I did get 234 warnings).
| + | then run |
| − | * *Important* Before we forget, open a new Terminal window (necessary to avoid the effects of "oldpath").
| + | dotnet build --configuration Release OpenSim.sln |
| − | * Now we need PowerPC versions of two libraries. Build each one and replace the compiled .dylib files in the opensim/bin folder.
| + | |
| − | ** libode.dylib http://cdnetworks-us-1.dl.sourceforge.net/project/opende/ODE/0.11.1/ode-0.11.1.zip
| + | |
| − | ** libopenjpeg-dotnet-2.1.3.0-dotnet-1.dylib (checked out with svn:)
| + | |
| − | svn co http://libopenmetaverse.googlecode.com/svn/libopenmetaverse/trunk/openjpeg-dotnet libopenmetaverse-read-only | + | |
| − | cd libopenmetaverse-read-only
| + | |
| − | ** To build, remove the Makefile file, which is for Linux, and rename Makefile.osx to just Makefile, then give the command: make )
| + | |
| − | ** Remove the other versions of the two libraries (similar names, different extensions, like "libode-x86_64.so". Two libode's and three libopenjpeg's).
| + | |
| − | * Configure your sim: Copy OpenSim.ini.example to OpenSim.ini and customize it per its comments.
| + | |
| − | * Likewise copy and customize StandaloneCommon.ini in bin/config-include
| + | |
| − | * Note that the comments say that the current SQLite plugin doesn't work on OS X. Either solve that, or install MySQL, which requires no compiling and is relatively easy to set up:
| + | |
| − | ** From http://downloads.mysql.com/archives.php?p=mysql-5.1&v=5.1.40, download MySQL 5.1.40 for 10.5 PowerPC (installer, not 64-bit)
| + | |
| − | ** Run the installer. (which installs to /usr/local)
| + | |
| − | ** Install MySQL.prefPane into System Preferences by double-clicking it.
| + | |
| − | ** Open the pref pane and start MySQL.
| + | |
| − | ** (Optional:) For unattended startup, install MySQLStartupItem (doesn't always work for me).
| + | |
| − | ** (Recommended:) In Terminal, do the one-time setup of MySQL with this command: mysql_secure_installation
| + | |
| − | ** In MySQL, create the opensim user per the comments in OpenSim.ini. Give it all the create privileges.
| + | |
| − | *** Since this is a Mac, you could use Sequel Pro (donationware) to do that in a nice GUI. Standard connection, host: 127.0.0.1 (if on the same Mac)
| + | |
| − | * You're ready to run OpenSim. In that new Terminal window, cd to your OpenSim-source/bin folder.
| + | |
| − | mono OpenSim.exe
| + | |
| − | * If all is well, you will be prompted "New region name []: "
| + | |
| − | * Turn to "Running OpenSim for the first time" on wiki page [[Configuration - OpenSim]]
| + | |
| − | * When fully up and running, the prompt is "Region (<region-name>) #"
| + | |
| − | ''Here are the earlier instructions for PowerPC, and others for Intel:''
| + | |
| − | ----
| + | |
| − | * OpenSim is now working on PowerPC Macs! Thanks to DrScofield and those who helped him. Current nightly builds for PowerPC are not working, not sure about Intel so use the 0.5 Build. OpenSim works on Intel Macs. I'm testing on PowerBook G4. Tested these step on 10.5, but not 10.4 but should work (Works on iMac G5 with OS 10.4.11, including expanding to local grid mode.
| + | |
| − | * Install XCode Developers Tools from DVD/CD Installation Disk or download from http://developer.apple.com/. You have to create an Apple account to access the downloads if you don't have an Apple account.
| + | |
| − | * Install X11 for 10.4 from the Optional Install from the DVD/CD Installation Disk. X11 for 10.5 is installed by default.
| + | |
| − | * Install Mono 1.2.5 from http://ftp.novell.com/pub/mono/archive/1.2.5/macos-10-universal/5/MonoFramework-1.2.5_5.macos10.novell.universal.dmg (The more recent releases Mono 1.2.6, 1.9.1 and 2.0.1 do not appear to work with these installation instructions And in Terminal or X11 edit the .profile file and add the following line:
| + | |
| − | export PKG_CONFIG_PATH="/Library/Frameworks/Mono.framework/Versions/Current/lib/pkgconfig/:${PKG_CONFIG_PATH}"
| + | |
| − | * Compile OpenSim
| + | |
| − | svn co http://opensimulator.org/svn/opensim/tags/0.5.0-release opensim
| + | |
| − | cd opensim
| + | |
| − | ./runprebuild.sh
| + | |
| − | nant
| + | |
| | | | |
| − | * Download and Compile libopenjpeg-libsl-2.1.2.0.dylib and libsecondlife.dll
| + | or just |
| − | * libopenjpeg-libsl-2.1.2.0.dylib:
| + | ./compile.sh |
| − | svn co http://opensimulator.org/svn/opensim-libs/old/libsl1550 opensim-libs | + | |
| − | cd opensim-libs/openjpeg-libsl
| + | |
| − | make -f Makefile.osx
| + | |
| − | cp libopenjpeg-libsl-2.1.2.0.dylib ../../bin
| + | |
| − | * Note: The Makefile that creates the libopenjpeg-libsl-2.1.2.0.so does not compile on PowerPC, but works properly on Intel Macs. Looks like a gcc issue with compile options. (It appears to work on iMac G5 with OS X 10.4.11.
| + | |
| | | | |
| − | * libsecondlife.dll: (for PowerPC Only, see details on this step [http://xyzzyxyzzy.net/2008/02/12/installing-opensim-on-powerpcor-of-eggs-and-virtual-worlds installing OpenSim on PowerPC…or: of eggs and virtual worlds])
| |
| − | cd .. (back into opensim-libs)
| |
| − | nant
| |
| − | cp bin/libsecondlife.dll ../bin
| |

| | | | |
| − | The instructions below also work on other RedHat Linux flavors such as CentOS or maybe Fedora.
| + | == Linux and Other Mono Platforms == |
| | | | |
| − | 1. Put the [http://download.opensuse.org/repositories/Mono/RHEL_5/Mono.repo Mono.repo] file in the /etc/yum.repo.d/ directory:
| + | === Install dotnet under Debian/Ubuntu === |
| − | $ sudo su -
| + | |
| − | $ cd /etc/yum.repos.d/
| + | |
| − | $ wget http://download.opensuse.org/repositories/Mono/RHEL_5/Mono.repo
| + | |
| − | Naturally use the most [http://download.opensuse.org/repositories/Mono up-to-date link for your distribution].
| + | |
| | | | |
| − | 2. Install Mono and related tools with yum:
| + | For Ubuntu 22.04 LTS and higher, dotnet is available in the distribution's repos. |
| − | $ yum install mono nant mono-jscript mono-nunit
| + | |
| − | Make sure to use nunit-console2 to run your tests.
| + | |
| | | | |
| − | === Fedora 12 & 13 ===
| + | For Ubuntu 20.04 LTS and lower, and for all versions of Debian, add Microsoft repository to your installation : |
| | | | |
| − | Fedora 12 and 13 installs are fairly simple. Nant and Mono now work out of the box with OpenSim. Incase you are completley new to this, here is a complete step by step guide to run OpenSim on a base install of Fedora (bare minimum of packages). It will also work on GUI installs.
| + | <source lang="bash"> |
| | + | # Get OS version info |
| | + | source /etc/os-release |
| | | | |
| − | 1. yum install wget nano nant libgdiplus mono-devel mono-jscript
| + | # Download Microsoft signing key and repository |
| | + | wget https://packages.microsoft.com/config/$ID/$VERSION_ID/packages-microsoft-prod.deb -O packages-microsoft-prod.deb |
| | | | |
| − | 2. [[Download]] opensim (wget [http://dist.opensimulator.org/opensim-0.7.0.1-source.tar.gz http://dist.opensimulator.org/opensim-0.7.0.1-source.tar.gz])
| + | # Install Microsoft signing key and repository |
| | + | sudo dpkg -i packages-microsoft-prod.deb |
| | | | |
| − | 3. tar -xf opensim-0.7.0.1-source.tar.gz
| + | # Clean up |
| | + | rm packages-microsoft-prod.deb |
| | | | |
| − | 4. mv opensim-0.7.0.1-source opensim
| + | # Update packages |
| | + | sudo apt update |
| | + | </source> |
| | | | |
| − | 5. cd opensim
| + | Then : |
| | | | |
| − | 6. ./runprebuild.sh
| + | <source lang="bash"> |

| | + | https://learn.microsoft.com/en-us/dotnet/core/install/linux-debian<br/> |
| | | | |
| − | 8. cd /bin
| + | === Prepare to compile === |
| | + | To create the several project files run on the folder opensim: |
| | | | |
| − | 9. cd /config-include/
| + | ./runprebuild.sh |
| | | | |
| − | 10. cp StandaloneCommon.ini.example StandaloneCommon.ini
| + | ==== Compile with Nant ==== |
| | + | On some mono versions, in particular old ones may need the use of nant to proper compile OpenSimulator, in that case just run: |
| | | | |
| − | 11. cd ..
| + | nant |
| | | | |
| − | 12. cp OpenSim.ini.example OpenSim.ini
| + | ==== Compile with xbuild ==== |
| | | | |
| − | 13. mono OpenSim.exe
| + | On mono versions you can just use xbuild. ''(msbuild is recommended for 0.9.1.0.0+)'' |
| | | | |
| − | === Fedora 5 ===
| + | xbuild |
| − | * I needed to build latest mono and nant from sources to build OpenSim successfully, the ones available in yum repository didn't work so I had to uninstall and build and configure the packages.
| + | |
| | | | |
| − | For detailed instructions go [http://ruakuu.blogspot.com/2008/06/installing-and-configuring-opensim-on.html here]
| + | xbuild is no longer recommended on mono 5.x, but currently still works (5.12) |
| | | | |
| − | === CentOS ===
| + | ''>>>> xbuild tool is deprecated and will be removed in future updates, use msbuild instead <<<<'' |
| | | | |
| − | On the assumption that you can run OpenSimulator from the binary distributions, this section will focus on how to compile OpenSimulator from the source distributions. For detailed instruction for running OpenSimulator, see [[Dependencies#CentOS]]. | + | On more recent mono versions Release configuration may give some performance gain, but you do lose some debug capabilities. |
| | + | to compile Release configuration: |
| | + | xbuild /p:Configuration=Release |
| | | | |
| − | First, install the development libraries of mono.
| + | ==== Compile with msbuild ==== |
| − | <pre>
| + | For Opensim 0.9.1 you can still use xbuild but Mono recommends the use of msbuild. You might need to install the package msbuild in addition to mono-complete for that. (Currently msbuild is included if you install mono-complete, on Ubuntu, from the official mono repositories. https://www.mono-project.com/download/stable/#download-lin ) |
| − | sudo yum install mono-addon-devel
| + | |
| − | </pre>
| + | |
| − | It will also come by mono-addon-data-oracle package.
| + | |
| | | | |
| − | Next, obtain NAnt from [http://nant.sourceforge.net/ NAnt Project Site]. See User Manual there for detailed instruction. As of 0.90, you will need to create startup script like that (given you have expanded NAnt to /usr/local/nant) :
| + | Use xbuild on the other cases as a last resort. |
| − | <pre>
| + | |
| − | sudo vi /usr/bin/nant
| + | |
| − | </pre>
| + | |
| − | Then inside this file :
| + | |
| − | <pre>
| + | |
| − | #!/bin/sh
| + | |
| − | exec mono /usr/local/nant/bin/NAnt.exe "$@"
| + | |
| − | </pre>
| + | |
| − | After that, make it executable :
| + | |
| − | <pre>
| + | |
| − | sudo chmod +x /usr/bin/nant
| + | |
| − | </pre>
| + | |
| | | | |
| − | You can now run runprebuild.sh and nant to compile OpenSimulator.
| + | Recent improvements, specially on JIT runtime, justify compiling in Release configuration, but you do lose some debug capabilities. |
| | | | |
| − | == openSUSE ==
| + | to compile with Debug configuration: |
| | + | msbuild |
| | | | |
| − | Install an openSUSE 11.1, 11 or 10.3 with its default options, add the online repositories
| + | to compile with Release configuration: |
| − | when finished installing do an online update with all the latest packages.
| + | msbuild /p:Configuration=Release |
| | | | |
| − | In yast install these packages, for running Opensim in standalone mode.
| + | to compile with the debug configuration and detailed opensim.log file can then be read with a text editor: |
| − | (there is a slight diffrence between 10.3 and 11/11.1 but following should be same)
| + | msbuild /p:Configuration=Debug /fileLogger /flp:logfile=opensim.log /v:d |
| − | subversion
| + | |
| − | nant
| + | |
| − | mono-jscript
| + | |
| − | - check that mono-core is installed
| + | |
| | | | |
| − | just in case you do not already have it installed
| + | you can specify the following values for the level of detail of the opensim.log file: |
| | + | q [quiet], m [minimal], n [normal], d [detailed] and diag [diagnostic]. |
| | | | |
| − | sudo zypper install mono-data-oracle
| + | To compile for .Net Framework 4.8 with mono >=6.12. you can run runprebuild48.sh instead of runprebuild.sh above. Not much gain doing that, if any. |
| | | | |
| − | A tip for OpenSuSE 11.1 users - you can install packages from the command line using the 'zypper' tool. For example, to install 'nant', use this command:
| + | == Ahead of Time compilation (AOT)== |
| | + | As you all know the files *.exe and .dll created by the compiling process above do no contain native code for the machine.<br> |
| | + | With those files, the native code required by the cpu is created at runtime, as needed, in a process known as Just in Time (JIT)<br> |
| | + | It is possible to do another compile stage on those files to create native code, that will ready when the program starts. This is the Ahead of time process (AOT).<br> |
| | + | Since JIT is done at runtime, it has limited time to do extensive code optimizations, AOT on the other hand can do all.<br> |
| | + | AOT should this way be faster to load, save some the memory needed by JIT work, and reduce latency due to code generation when a new code section is needed.<br> |
| | + | This way AOT helps reduce the huge performance gap between C# and a more proper language like C++, even considering JIT can do some optimization dependent on current code execution state, that AOT can't. (if you think c# is as fast as competent c++ code, better change what you are smoking...)<br> |
| | + | In fact both .net and mono do AOT on their components during install<br> |
| | + | JIT will still be active, compiling some other code at run time. OpenSim and used .net/mono framework parts depend on it.<br> |
| | | | |
| − | sudo zypper install nant
| + | For Linux, 0.9.2.0 now includes scripts makeaot.sh and cleanaot.sh to help testing AOT.<br> |
| | + | Run makeaot.sh after the compile stage above, to generate the native code files. The option -O=all must be added to mono when executing opensim.exe, ex:<br> |
| | + | mono --desktop -O=all OpenSim.exe |
| | + | Script cleanaot.sh removes the binary files used by AOT. You must run it if you recompile the code (to be safe even if running makeaot).<br> |
| | + | <b>DO NOT FORGET to run makeaot.sh or cleanaot.sh after recompile!</b><br> |
| | + | The generated files are specific for that machine. <b>Do not copy the native code files to other machine, unless it is absolutely identical</b><br> |
| | + | The original .exe and .dll are still needed<br> |
| | | | |
| − | If you just want to use SQLite then jump to last section
| + | AOT is also possible in windows, but using different tools, and those add things to central repository on the machine, harder to isolate and maintain. see [https://docs.microsoft.com/en-us/dotnet/framework/tools/ngen-exe-native-image-generator ngen]<br> |

| − | * Optional mysql - for Opensim running in Grid mode:
| + | Macs are.. Macs.. Future models may totally forbid JIT, like Apple mobile products do. Mono AOT on current Macs may work as on Linux<br> |
| − | Install these mysql packages via yast
| + | |
| − | mysql
| + | |
| − | mysql-client
| + | |
| − | mysql-administrator
| + | |
| − | mysql-gui-tools
| + | |

| + | |
| | | | |
| − | (note that selecting mysql in the Yast2 Installer will select the other packages automatically) | + | In practical use, don't expect much more than a bit faster loading.<br> |
| | + | Additionally, since compilation is different, it may add new issues. So test with care<br> |
| | + | Opensim performance issues are mostly on its own code, terrible bad communications protocols, use of bad .net/mono framework code (demo quality in same cases), etc.<br> |
| | + | And of course eternally broken GC<br> |
| | + | But... well every ns counts..<br> |
| | | | |
| − | Before building create the mysql database.
| + | = Configuration = |
| − | /etc/init.d/mysql start
| + | |
| − | mysql -u root -p -h localhost
| + | |
| − | (when asked for password just hit enter)

| − | | + | |
| − | mysql> create database opensim;
| + | |
| − | mysql> use opensim;
| + | |
| − | mysql> create user 'opensim'@'localhost' identified by 'thePassword';
| + | |
| − | mysql> grant all on *.* to 'opensim'@'localhost';
| + | |
| − | mysql> quit
| + | |
| − | | + | |
| − | *note that the '''grant all''' command may differ if you're adding the opensim database to an existing mysql installation.
| + | |
| − | | + | |
| − | On current builds set the connection string inside bin/OpenSim.ini after coppying the OpenSim.ini.example file.
| + | |
| − | If you are changing to MySQL from SQLite, the connection string for mysql also exists in the bin/Region/*xml files.
| + | |
| − | * It is '''important''' to remember this if you start out using the built-in SQLite database engine.

This page covers building OpenSimulator from source code on multiple platforms. Please help us keep this page up to date as the project progresses. If you just want to run OpenSimulator, Download and run the binary build instead. In the most cases, you should be fine with binaries.
Although this page is long, building is generally quite simple. See the BUILDING.txt file in the distribution itself for simplified instructions.
Microsoft stopped the development of .Net Framework and Mono, replacing them by new dotnet
This is a significant breaking change that we try to follow on 0.9.3.0.
Load the generated OpenSim.sln into Visual Studio and build the solution, or just run
Other platforms may have own mono distributions, or may need to compile mono on them.
Other libraries used by OpenSimulator can be found at our opensim-libs git repo:
You may need to compile them for your platform, in particular the unmanaged ones like Bullet or ODE native code libraries
For Ubuntu 22.04 LTS and higher, dotnet is available in the distribution's repos.
For Ubuntu 20.04 LTS and lower, and for all versions of Debian, add Microsoft repository to your installation :
On some mono versions, in particular old ones may need the use of nant to proper compile OpenSimulator, in that case just run:
On mono versions you can just use xbuild. (msbuild is recommended for 0.9.1.0.0+)
On more recent mono versions Release configuration may give some performance gain, but you do lose some debug capabilities.
to compile Release configuration:
For Opensim 0.9.1 you can still use xbuild but Mono recommends the use of msbuild. You might need to install the package msbuild in addition to mono-complete for that. (Currently msbuild is included if you install mono-complete, on Ubuntu, from the official mono repositories. https://www.mono-project.com/download/stable/#download-lin )
Recent improvements, specially on JIT runtime, justify compiling in Release configuration, but you do lose some debug capabilities.
to compile with the debug configuration and detailed opensim.log file can then be read with a text editor:
you can specify the following values for the level of detail of the opensim.log file:
To compile for .Net Framework 4.8 with mono >=6.12. you can run runprebuild48.sh instead of runprebuild.sh above. Not much gain doing that, if any.
As you all know the files *.exe and .dll created by the compiling process above do no contain native code for the machine.
With those files, the native code required by the cpu is created at runtime, as needed, in a process known as Just in Time (JIT)
It is possible to do another compile stage on those files to create native code, that will ready when the program starts. This is the Ahead of time process (AOT).
Since JIT is done at runtime, it has limited time to do extensive code optimizations, AOT on the other hand can do all.
AOT should this way be faster to load, save some the memory needed by JIT work, and reduce latency due to code generation when a new code section is needed.
This way AOT helps reduce the huge performance gap between C# and a more proper language like C++, even considering JIT can do some optimization dependent on current code execution state, that AOT can't. (if you think c# is as fast as competent c++ code, better change what you are smoking...)
In fact both .net and mono do AOT on their components during install
JIT will still be active, compiling some other code at run time. OpenSim and used .net/mono framework parts depend on it.
For Linux, 0.9.2.0 now includes scripts makeaot.sh and cleanaot.sh to help testing AOT.
Run makeaot.sh after the compile stage above, to generate the native code files. The option -O=all must be added to mono when executing opensim.exe, ex:
Script cleanaot.sh removes the binary files used by AOT. You must run it if you recompile the code (to be safe even if running makeaot).
DO NOT FORGET to run makeaot.sh or cleanaot.sh after recompile!
The generated files are specific for that machine. Do not copy the native code files to other machine, unless it is absolutely identical
The original .exe and .dll are still needed
AOT is also possible in windows, but using different tools, and those add things to central repository on the machine, harder to isolate and maintain. see ngen
Macs are.. Macs.. Future models may totally forbid JIT, like Apple mobile products do. Mono AOT on current Macs may work as on Linux
In practical use, don't expect much more than a bit faster loading.
Additionally, since compilation is different, it may add new issues. So test with care
Opensim performance issues are mostly on its own code, terrible bad communications protocols, use of bad .net/mono framework code (demo quality in same cases), etc.
And of course eternally broken GC
But... well every ns counts..
