Hi David.... Found a git repo and cloned it. But the build fails.
Tried cmake . make Also tried mkdir Build cd Build cmake .. make And tried cmake . make CC=clang CXX=clang++ All end in the same way: (With the tarball version, all I did was make -f Makefile) /usr/local/src/gnustep-libobjc2/objc/message.h:44:6: note: 'objc_msgSend_stret' is a builtin with type 'id (id, SEL, ...)' 1 warning generated.
