Re: Glib::ustring in mingw
Problem solved, more or less. The issue is with gcc compiler. Apparently the gtkmm bundle package is build with gcc-4.6.2, and some hack or other is done to get glib/glibmm to compile. If you try to compile and link your program with a different gcc version (I tried 4.7.0 and 4.7.2) the ustring constructor in glibmm is broken and will invariably lead to SEGV. Using a mingw with the packaged compiler and tools, there is no problem with Glib:ustring. So the quick fix is to install mingw with the packaged gcc (4.6.2) and use this to build gtkmm packages. Plain gtk+ will most probably work correctly with gcc-4.7.2 or later. 2013/9/9 Alcione Ferreira alcione.som...@gmail.com Only confirmed! Managed to solve your problem? Só confirmando!

RE: Glib::ustring in mingw
You can never trust using prebuilt C++ libraries made with any other version of any compiler than precisely the one that you’re using. The C++ ABI is not sufficiently standardised to trust cross-compatibility. It’s often not even safe to trust prebuilt libraries even if you do know they were made with the right compiler version, unless you also know exactly which #defines and command-line flags were in effect at the time it was built. (And since it’s often hard to be sure of all of that, especially with patches and updates occasionally breaking things behind the scenes, it’s usually better to just not trust prebuilt libraries at all.)
