This is currently biting everyone trying to compile open source projects with Apple's latest clang (clang-503.0.38 from March 2014). To avoid it one needs to either remove all unused command-line arguments from all clang command lines in all packages that use clang (probably a huge task) or add the flag -Wno-error=unused-command-line-argument-hard-error-in-future to all clang command lines. For the fftw package this can be done by adding this flag to the SetCFLAGS field. It then builds OK. For other packages this may be more tricky. In any case, the remedy that is proposed on some web discussions, namely setting the environment variable ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future does not work. It works perhaps inside xcode projects, but not in autotools projects or others. -- Martin ------------------------------------------------------------------------------ Learn Graph Databases - Download FREE O'Reilly Book "Graph Databases" is the definitive new guide to graph databases and their applications.
