Created attachment 47944 [details, diff] Ebuild solving the bug + version bump to 0.9.1 This can be fixed by adding -fpermissive to the CXXFLAGS which turns the errors into warnings. As there was a new version available, I used it for the new ebuild. Also had to fix two missing includes. (The muse-developer already knows about the problem, see http://lists.dyne.org/muse/msg00819.php for details)
Created attachment 47945 [details, diff] Patch necessary for the ebuild
Created attachment 49034 [details, diff] Misc code fixes patch The include patch isn't enough, at least with GCC 3.4. The attached patch fixes invalid C++ syntax used, making MuSE compilable (tried to compile in an amd64 system, but the changes doesn't make differences for x86 systems, instead 64-bit system should now work, fixing the mismatch between gsize and guint).
patches added to portage tree. thanks!
