Building gnomemeeting with -O3 results in a gnomemeeting which works with V4L devices but not with static pictures or the builtin moving gnome meeting logo. (A correctly working gnomemeeting should allow one to select "Picture" in Preferences->Video Devices->Video Plugin. With -O3 this is not possible). I changed my CFLAGS to -O2 and it seems to work correctly. The problem is more serious then just a missing feature because it causes segfaults on systems without webcams. Various compile flags are known to cause problem with gcc 3.4: http://mail.gnome.org/archives/gnomemeeting-list/2005-January/msg00005.html But I'm running gcc 3.3.4. Gnomemeeting developers suggested this might be because of patches applied to gcc 3.3. Not sure exactly which part of -O3 causes the problem. Gnomemeeting developers suggested using -fno-unit-at-a-time but then ./configure gives the following error: checking for C compiler default output file name... configure: error: C compiler cannot create executables According to the developers PWLib and openh232 may also need to have lower optimizations to prevent segfaults. Indeed, even with -O2, gnomemeeting segfaults on exit. So I rebuilt PWlib, openh232, and GM without any -Ox flags. But that didn't help, GM still segaults on quit. Anyway, at least we need to strip -O3 from use flags and replace it with -O2 for gnomemeeting.
