[Bug 397744] [NEW] monodevelop debugger not working

[Martin Dederer]

Public bug reported:

Binary package hint: monodevelop

I tested the debugger support in monodevelop and it turns out it does
not work as expected. Whenever i execute in debug mode monodevelop
actually enters the debug mode but i can't use any debug functions like
stepping etc.

The following output is generated on the terminal:


foo at bar:~$ monodevelop 
WARNING: Cannot find Mozilla directory containing libgtkembedmoz.so. Some Addins may not be able to function. Please set MOZILLA_FIVE_HOME to your Mozilla directory.
WARNUNG [2009-07-10 10:23:10Z]: Inotify watch limit is too low (8192).
MonoDevelop will switch to managed file watching.

It looks like Mono.Debugger is expecting a different version of the Mono.Cecil library than the one that is installed.

foo at bar:~# find /usr/lib/mono/gac/Mono.Cecil
