Hi Andrew: That thread implies the problem is caused by the build scripts for GTK+ which apparently use the -flto link time option that is described at <https://gcc.gnu.org/onlinedocs/gcc/Optimize-Options.html>. However, there is no mention of "flto" in the epa_build tree so unless -flto is on by default with gcc-4.9.0, the source of the issue with epa_build of GTK+ (or the pango/cairo subset of that) must be something else. Also note that gcc-4.7.2 knows nothing about the -flto option so if the solution is turning off that option for gcc-4.9.x that can only be done for that version of gcc. In sum, dealing with this epa_build issue for pango/cairo is likely not going to be a simple fix so we should look at this again post-release. Alan __________________________ Alan W.
