You might want to fix these warnings. The first one and the last one seem like they could cause nondeterminism. Also, you shouldn't be adding -I/usr/include/mpi. mpicc will add the right -I option for you (e.g., do you know for sure that your MPI header files are in /usr/include/mpi?). It's useless at best, and harmful at worst (E.g., if some other MPI implementation is installed into /usr/include/mpi). > no MPI -program which was based on > > **** Build of configuration Debug for project snd_test **** > > make all > Building file: ../main.c > Invoking: GCC C Compiler > gcc -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"main.d" > -MT"main.d" -o "main.o" "../main.c" > Finished building: ../main.c > > Building target: snd_test > Invoking: GCC C Linker > gcc -o "snd_test" ./main.o -lsndfile > Finished building target: snd_test I notice that you're not including -Wall and a bunch of other compiler flags in the non-MPI install. I also notice that you're not compiling the same .c files at all. So if I'm understanding this thread right -- and I may well not be -- it seems like you're saying: - when I use gcc to compile main.c, the program runs file - when I used mpicc to compile ../src/snd_0.1.c, the program fails If that's the case, your comparing apples to oranges here. -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
