View source for CentOS 5.2 Build Instructions

The following process worked for me, please feel free to improve it as it may not be the best way :)

NB In progress do not follow these instructions yet!!

From a fresh install:

  # yum update
  # yum install subversion ruby

To get Mono 1.9.1 I added the Mono.repo file in the /etc/yum.repo.d/ directory:

  # sudo su -
  # cd /etc/yum.repos.d/
  # wget http://download.opensuse.org/repositories/Mono/RHEL_5/Mono.repo

I then installed mono

  # yum install mono nant libgdiplus

So far so good, mono -V shows 1.9.1 has installed :)

Now just a couple of other things that you may need:

  # yum install swig autoconf gawk bison gcc

And then build and install mono 2.0.1 from source

  # wget http://ftp.novell.com/pub/mono/sources/mono/mono-2.0.1.tar.bz2
  # tar xf mono-2.0.1.tar.bz2
  # cd mono-2.0.1
  # ./configure --with-libgdiplus=yes
  # make (may take a while)
  # make install

Yay! mono -V and I have Mono 2.0.1 :)

Now all i have to do is open the right ports and install OpenSim as usual...
