OK. Thanks David. I changed my install script to build libobjc manually and have GNUstep find it. When I try to configure core/base I get: configure:13162: checking whether objc really works configure:13192: clang -o conftest -g -O2 -I/opt/local/include -I/opt/local/GNUstep/System/Library/Headers -I/opt/local/GNUstep/Local/Library/Headers -I/opt/local/GNUstep/Local/Library/Headers -fgnu-runtime -x objective-c -L/opt/local/GNUstep/System/Library/Libraries -L/opt/local/GNUstep/Local/Library/Libraries -L/opt/local/GNUstep/Local/Library/Libraries conftest.c -lrt -ldl -lpthread -rdynamic -pthread -shared-libgcc -fexceptions -fgnu-runtime -L/root/GNUstep/Library/Libraries -L/opt/local/GNUstep/Local/Library/Libraries -L/opt/local/GNUstep/System/Library/Libraries -lobjc -lm >&5 clang: warning: argument unused during compilation: '-shared-libgcc' /usr/local/lib/libobjc.so: undefined reference to `dispatch_async_f' /usr/local/lib/libobjc.so: undefined reference to `dispatch_queue_create' clang: error: linker command failed with exit code 1 (use -v to see invocation) It appears it is not trying to link to libdispatch. If I export LDFLAGS="-ldispatch" before configure then the build works. The old way I was doing things (letting GNUstep build libobjc) this wasn't an issue. Why would this be the case?
