Err... I wouldn't expect that to work on any POSIX platform. gcc searches for includes in directories specified by -I on its command line, not based on $PATH... > [EMAIL PROTECTED] /cygdrive/c/cygwin/tmp/mpi/mpich2-1.0.6p1/examples > $ make hellow > gcc -I../src/include -I../src/include -O2 -c hellow.c > hellow.c:13:17: mpi.h: No such file or directory > hellow.c: In function `main': > hellow.c:21: error: `MPI_COMM_WORLD' undeclared (first use in this function) > hellow.c:21: error: (Each undeclared identifier is reported only once > hellow.c:21: error: for each function it appears in.) > make: *** [hellow.o] Error 1 See, it's searching in "../src/include", in addition to the default compiler directories. If the Makefile is 'standard', you could probably do: make CFLAGS='-I /cygdrive/c/Program\ files/MPICH2/include' hellow to convince it to search in the MPICH2 include dir as well. (you may or may not need the \ before the space in program files, depending on how make does its argument splitting, I'm not really sure) But anyway, this isn't really on-topic here, since this is just a general "How to compile in a POSIX environment" question. ~Matt -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
