Re: [Ltib] Crash when executing gtk application

[Stuart Hughes]

Hi Rogerio,

There are 2 patches that I see:

Patch1          : gtk2-2.12.1-builtin_icons.patch
Patch2          : gtk2-2.12.1-no-update-icon-cache.patch

The first looks harmless (can you confirm?).
The second one though I recall was to fix a build problem on Fedora. 
The issue is that the host side tool "gtk-update-icon-cache" is not 
always compatible with the gtk2 package we have and so why I hoped the 
builtin default would work okay (gtkbuiltincache.h).  It would be good 
if it could be made to work this way because it de-couples the build 
from the host platform.  If it can't be made to work then the prospect 
of including gtk-update-icon-cache (and all the packages that provide 
it) looms.  It scares me to have to provide too many host packages in 
/opt/ltib/usr/....

* Would it be possible to try to figure out why the built-in 
gtkbuiltincache.h causes a SEGV on your target?

* Can you think of another way around this?

So far as X/framebuffer go, the only testing I did was some limited 
Framebuffer X testing of the gtk test programs that come with the 
package on a MAG G4 Sawtooth.

Unfortunately I don't have time to dig into this right now, but if you 
(or anyone) can spare the time to fix this in "the right way", I'd 
appreciate it.

Regards, Stuart
