Hi, I've mentioned previously I've used “MKLIBS = mklibs-copy” to build g-i images, because I was facing some mklibs failures in X modules.
The first patch aims at fixing the way mklibs is throwing python exceptions. The second patch makes it possible to use that instead (meaning some library reduction can happen, as opposed to using mklibs-copy): MKLIBS = mklibs -X /usr/lib/xorg/modules AFAICT (please keep in mind I'm quite new to this), the issue was that an X module was needing some symbols available in another X module, without referencing it (I guess one plugin gets access to the other plugin's symbols through the Xorg binary itself). Comments welcome. Mraw, KiBi.
Modernize exception raising.
Raising string exceptions is deprecated, turn strings into proper
Exception objects.
