 Posted: Sun Aug 14, 2005 5:53 pm Post subject: mono-rebuild.sh: rebuild broken Mono applications |
 |
|
After updating *-sharp packages and other libraries with mono bindings, mono applications that use those libraries sometimes start to fail with errors like:
| Code: | ** (/usr/lib/muine/muine.exe:8850): WARNING **: The following assembly referenced from /usr/lib/muine/muine.exe could not be loaded:
Assembly: dbus-sharp (assemblyref_index=13)
Version: 0.35.0.0
Public Key: 9eef2692033670f5
The assembly was not found in the Global Assembly Cache, a path listed in the MONO_PATH environment variable, or in the location of the executing assembly (/usr/lib/muine). |
What's needed is a rebuilding script like revdep-rebuild or perl-cleaner.
mono-rebuild.sh version 0 - please test and report back!
Dependencies: sys-apps/file, app-shells/bash, dev-lang/mono (of course).

Hey!
This looks great! Something I've been meaning to get around to writing. Is there any chance you could look into actually integrating it somehow into revdep-rebuild though? Keeping things like this in one central tool, but extended for other realms of dependancy checking than native .so stuff would be a big help for things like this.
(It'd be especially nice to have tonight, since I just bumped all the *-sharp stuff for the new beta release, which changed assembly versions and will mean recompilation of monodevelop, new muine, etc for folks).

Hmm...
Well, revdep-rebuild certainly has things that'd be useful (rebuild reordering, sane interface, etc.) I'll have a look at modularising it; should be feasible (and quite interesting) but might take a little while, so don't expect a modularised revdep-rebuild immediately.
