In an attempt to limit runtime dependencies, I am using static libraries where possible. Under OSX (10.4.4) I get the following error when I try to link my application:
/usr/bin/ld: multiple definitions of symbol _munmap /usr/lib/gcc/powerpc-apple-darwin8/4.0.1/../../../libSystem.dylib(munmap.So) definition of _munmap [path-to-mpi-libs]/libopal.a(memory_darwin_component.o) definition of _munmap in section (__TEXT,__text) I have configured R8901 with --disable-shared and --enable-static (I have also tried --with-memory-manager=none, with no effect). If I understand correctly, openmpi's munmap depends on munmap being a weak symbol. But according to nm -mg, munmap is not a weak symbol in libSystem.dylib (a.k.a. libc.dylib). In fact there aren't any weak symbols in this library. It would seem that this is technically a problem with shared libraries as well, but it would only be detected at run time because there is so much indirection (empirically, there is no problem problem with dynamic libraries, though). Any ideas on a solution to this problem? Bill
