I mean you'll need to specify it for everything. If you look at how the FreeBSD GNUstep ports are set up, they pass the correct arguments to the various configure things to make this Just Workâ˘. It sounds like you didn't specify it for base / gui. The easiest thing to do is make -make add the flag for you. > (If I try -fobjc-nonfragile-abi I get: clang-3.5: warning: argument unused > during compilation: '-fobjc-nonfragile-abi') Yes, if you also specify -fobjc-runtime then it's redundant.
