XBuild has a cache file that has things like these:
<File path="/usr/local/lib/pkgconfig/gtk-sharp-3.0.pc" lastWriteTime="2012-12-12T01:40:39+00:00" name="gtk-sharp-3.0" version="2.99.1" description="Gtk# - GNOME .NET Binding" requires="glib-sharp-3.0 gio-sharp-3.0" targetFramework=".NETFramework,Version=v2.0">
<Assembly name="cairo-sharp" version="220.127.116.11" culture="neutral" publicKeyToken="0738eb9f132ed756" file="/usr/local/lib/mono/gtk-sharp-3.0/cairo-sharp.dll" />
<Assembly name="gdk-sharp" version="18.104.22.168" culture="neutral" publicKeyToken="35e10195dab3c99f" file="/usr/local/lib/mono/gtk-sharp-3.0/gdk-sharp.dll" />
<Assembly name="gtk-sharp" version="22.214.171.124" culture="neutral" publicKeyToken="35e10195dab3c99f" file="/usr/local/lib/mono/gtk-sharp-3.0/gtk-sharp.dll" />
The problem with this is that xbuild doesn't remove entries from this cache file, so:
- Entries get duplicated, like above.
- Entries are not removed which should be removed, because they don't exist anymore in the system.
So if a person goes and uninstalls a package that has a .pc file referenced by xbuild, xbuild will still resolve references to the .pc file!
So there are several things we need to do here:
- Not insert duped items (minor).
- Remove <File> elements that map to a non-existent pc file.
- Remove <Assembly> elements that map to a non-existent assembly.
Forgot to say, I found this file here: $HOME/.config/xbuild/pkgconfig-cache-2.xml
I just ran into a problem which turned out to be caused by this bug. I removed a package and when I attempted to build with xbuild it tried to use the assembly from the package which was no longer installed.
Deleting the cache file $HOME/.config/xbuild/pkgconfig-cache-2.xml resolved the problem.
Same problem here. An existing xbuild cache broke my schroot build, because the cache refered to items that did not exist inside the schroot.
Deleting the cache fixed that for me.
I made a pull request with a fix for this issue: https://github.com/mono/mono/pull/849
