Both 1.8 and 1.8.1 fail to build for the same reason.
Created attachment 526486 [details, diff] 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) +./Makefile:CPPFLAGS += -D__OBJC_RUNTIME_INTERNAL__=1 -D_XOPEN_SOURCE=500 -D_DEFAULT_SOURCE=1 +./CMakeLists.txt:add_definitions( -D_XOPEN_SOURCE=700 -D_DEFAULT_SOURCE=1)
Created attachment 526490 [details, diff] 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.
https://github.com/gnustep/libobjc2/pull/68
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)
