| + | #Redirect [[Troubleshooting#How to do a clean rebuild? (e.g. after 'APPLICATION EXCEPTION DETECTED' after rebuild with updated source)]] |
| − | When you build from source, then update the source, rebuild and try to run, you get strange runtime exceptions, usually along the lines of
| + | |
| − | | + | |
| − | APPLICATION EXCEPTION DETECTED: System.UnhandledExceptionEventArgs
| + | |
| − | Exception: System.MissingMethodException
| + | |
| − | | + | |
| − | ==The Problem==
| + | |
| − | When you build the source, it's 'compiled' into runnable files called 'dlls' or Dynamic Link Libraries.
| + | |
| − | These have the extension .dll and are added to your local installation, and are not governed by source control.
| + | |
| − | When we change where these dlls are created, the 'old' ones, from previous builds, will still be there.
| + | |
| − | This will cause the program to try and load these old dlls, with unexpected results.
| + | |
| − | | + | |
| − | ==The Solution==
| + | |
| − | Usually, any of these remedies should fix the problem:
| + | |
| − | * Remove all OpenSim.*.dll (only files that starts with "OpenSim." and ends in ".dll", like "OpenSim.Framework.dll") recursively from your installation directory, then rebuild and run.
| + | |
| − | * Do a 'nant clean' if you're using Nant, rebuild and run.
| + | |
| − | * Do a clean checkout, build that from scratch, then copy over all data files (*.db, *.xml, *.ini) from your old installation, rebuild and run.
| + | |
| − | | + | |
| − | If all else fails, join #opensim on freenode, or send an email to theopensim-users mailing list.
