[Trilinos-Users] Building Trilinos using Xcode with MPI

[Heroux, Michael A]

I am trying to make an MPI build of Trilinos on a Mac using Xcode and its default compilers.  I can complete a serial build in Xcode without difficult (after turning off Fortran kernels) and I can do both serial and MPI builds using the command line approach.

I can compile source files using Xcode, but have not been able to link.  The problem seems to be that I cannot override the native g++ 4.2 compiler as the linker (with mpicxx).  I have tried putting the MPI libraries in the extra libs link variable but that does work (yet) either.  I am wondering if anyone has made it past these issues already before going further myself.

Is this a Cmake issue with Xcode? I can get Cmake to generate the Unix Makefiles fine and get a proper MPI build that way.

I am using Cmake 2.8.2 and Xcode 3.2.3 on Snow Leopard with the native GCC 4.2.1 compilers.

Below is output from the first failed link in my build.

Thanks.

Mike
