Qt Creator would crash if I opened the Qt resource editor if Qt 4.8.2 and Qt Creator 2.5.2 were compiled with it. MinGW-builds GCC 4.7.1 64-bit didn't crash.
I switched to MinGW-builds 4.6.3 for both 32-bit and 64-bit and it seems to be working fine. Also, GCC 4.7.x has problem where it runs out of memory in some cases (https://bugs.archlinux.org/task/28329). > - make with -j support Patch for that here: http://www.mail-archive.com/make-w32@gnu.org/msg02283.html.

Some other MinGW-related notes follow. Compiling WebKit fails due to mingw32-make using temporary batch files which are subject to 8191 character limit per line. Can be fixed using instructions at: http://old.nabble.com/Re%3A-command-line-limit-in-mingw-make-p33909533.html ICU can be compiled with MinGW-w64 after applying: http://bugs.icu-project.org/trac/changeset/31770/icu/trunk/source/tools/toolutil/pkg_genc.c?format=diff&new=31770 Regards, Jonathan _______________________________________________ Development mailing list Development@qt-project.org http://lists.qt-project.org/mailman/listinfo/development
