libobjc2-1.8.1-r1.ebuild.patch
I have added a 1 line ebuild patch to fix the compile issues. It looks like clang's default libc does not support __cxa_allocate_exception so it needs to be linked against gcc. I doubt this is a good fix, but it appears to work around the issue with little effort.
A good portion of the warnings can be addressed by patching a couple of files, it looks like these were applied to the master branch but no release yet.
-./Makefile:CPPFLAGS += -D__OBJC_RUNTIME_INTERNAL__=1 -D_XOPEN_SOURCE=500 -D__BSD_VISIBLE=1 -D_BSD_SOURCE=1
-./CMakeLists.txt:add_definitions( -D_XOPEN_SOURCE=700 -D__BSD_VISIBLE=1 -D_BSD_SOURCE=1)

clang_cxa_allocate_exception.patch
Patch suitable for /etc/portage/patches/gnustep-base/libobjc2 or epatch. This also fixes a bunch of the warnings. Last two seem to require a (cast) and are not addressed.
This should be fixed upstream. I see upstream report marked as merged some time ago, so we can mark this fixed with just released 2.1 (in tree in next sync) |
