Hi Rogerio,I've checked in a change to comment out the offending patch. I've also added a re-build dependency so that if XORG_SERVER is changed cairo gets rebuilt.

Hi Stuart, I agree with you. I am using ubuntu 9.04 (jaunty) and this patch is not necessary to compile gkt in my environment. Regards, Rogerio 2009/9/16 Stuart Hughes <address@hidden>:Hi Rogerio, Thanks for looking. I'm inclined to pull out gtk2-2.12.1-builtin_icons.patch for the time being until this is resolved as even if it fixes some compilation problems, it doesn't actually run on the target. What do you think? Regards, Stuart Rogério de Souza Moraes wrote:Hi Stuart, I compiled gtk2 again using one patch at once. Using the patch gtk2-2.12.1-builtin_icons.patch (the one that we thought that was harmless) I got the segmentation fault. The signal of segmentations fault is caught at the file gtkicontheme.c. This is the file that when I debug using gdb, is showed as responsible for the segfault. Program received signal SIGSEGV, Segmentation fault. find_image_offset (cache=0xf21c0, icon_name=0x679b8 "leafpad", directory=0x402e1948 "16") at gtkiconcache.c:228 228 n_buckets = GET_UINT32 (cache->buffer, hash_offset); Using the patch gtk2-2.12.1-no-update-icon-cache.patch the gtk programs worked without problems. I spent a lot of time already to discovery why the applications were crashing but I couldn't solve this. Unhappy I can't spend more time on this because I have short time to finish the project I am working on it. So the patch gtk2-2.12.1-no-update-icon-cache.patch is ok but the patch gtk2-2.12.1-builtin_icons.patch causes segfault in GTK applications that are more complex at handling with icons. Regards Rogerio 2009/9/16 Stuart Hughes <address@hidden>: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 Rogério de Souza Moraes wrote:Hi Stuart, thanks for helping, I tried to change the permission of "/usr/share/icons" and "/usr/share/pixmaps" and it didn't worked. So looking at the spec and analysing the patches that you put in gtk.spec, I saw that your patches were changing files that are responsible for the gtk icon cache. I remove the patches and compiled. For my surprise the programs that was crashing, now are working. Looking at the patches appear that you did them to handle some problems when you build ltib in FC4 and FC5. That's right? Another detail that now I am compiling GTK with X11. I didn't test build gtk using just direct frame buffer but I think that even without X11 it can works. For simple applications that use gtk, it does not crash, but for applications that are more complex, it always crashes. My build host is an ubuntu 9.04 and my target is an IMX27 freescale board. Regards Rogerio 2009/9/15 Stuart Hughes <address@hidden>:Hi Rogerio, I've not seen this, but have not used gtk much on the target boards. Make sure to check that you have the icons on the target and that they're readable etc. Regards, Stuart Rogério de Souza Moraes wrote:Hi, I am building LTIB in an Ubuntu 9.04.
