Hi - I'm trying to compile a simple hello world program with mpicc,
$ cat test.c #include <stdio.h> main() { printf ("Hello World!\n"); } but I'm seeing this issue: $ ~/pkg/openmpi/1.4.3_bigmac/bin/mpicc test.c dyld: Symbol not found: _evsignal_base Referenced from: /uufs/ chpc.utah.edu/common/home/u0552682/pkg/openmpi/1.4.3_bigmac/lib/libopen-pal.0.dylib Expected in: flat namespace in /uufs/ chpc.utah.edu/common/home/u0552682/pkg/openmpi/1.4.3_bigmac/lib/libopen-pal.0.dylib Trace/BPT trap I found this previous thread, http://comments.gmane.org/gmane.comp.clustering.open-mpi.user/13033 , which suggested adding the installation directory's lib/ to LD_LIBRARY_PATH would fix things, but it did not: $ export LD_LIBRARY_PATH="${HOME}/pkg/openmpi/1.4.3_bigmac/lib:${LD_LIBRARY_PATH}"; ~/pkg/openmpi/1.4.3_bigmac/bin/mpicc test.c dyld: Symbol not found: _evsignal_base Referenced from: /uufs/ chpc.utah.edu/common/home/u0552682/pkg/openmpi/1.4.3_bigmac/lib/libopen-pal.0.dylib Expected in: flat namespace in /uufs/ chpc.utah.edu/common/home/u0552682/pkg/openmpi/1.4.3_bigmac/lib/libopen-pal.0.dylib Trace/BPT trap Any suggestions on what I might be doing wrong?
