[Trilinos-Users] Cmake not recognizing cygwin mpi compilers

[Hogan Jr, Roy E]

Hello Jim,

Thank you for your reply.  I am using Open MPI  1.7.1 built on Cygwin...

I am beginning to  wonder if it is a protection issue with Cygwin or an issue with cmake.   It appears that cmake is not finding the mpi compilers/wrappers.

Thank you for your help..

Roy,

What is the output you get for

/usr/bin/mpicc --version

-- Check for working C compiler: /usr/bin/mpicc
CMake Error: your C compiler: "/usr/bin/mpicc" was not found.   Please set CMAKE_C_COMPILER to a valid compiler path or name.

The output from cmake seems to indicate that mpicc is not located at /usr/bin/mpicc

What version of MPI is installed on your machine?

Jim

Greetings,

I've been trying to build Trilinos on Cygwin without any luck.  It appears to me that Cmake is not finding the "mpi" wrappers/compilers.    I am attaching the build script (do-configure-testing), the captured screen output (do-configure-testing.log), and the CMakeCache.txt files.  I have tried to specify these directly, but it did not work either.

I would appreciate any suggestions.

Thanks,

Roy Hogan
