[Trilinos-Users] MPI_C_COMPILER conflict with CMAKE_C_COMPILER

[Pavel Jiránek]

This is my script:

export CC=/usr/local/bin/mpicc
export CXX=/usr/local/bin/mpic++

cmake \
    -D Trilinos_ASSERT_MISSING_PACKAGES:BOOL=OFF \
    -D BUILD_TESTING:BOOL=ON \
    -D CMAKE_BUILD_TYPE:STRING=RELEASE \
    -D CMAKE_INSTALL_PREFIX:PATH=$HOME/local/opt/trilinos \
    -D CMAKE_OSX_ARCHITECTURES:STRING=x86_64 \
    -D CMAKE_VERBOSE_MAKEFILE:BOOL=ON \
    -D TPL_ENABLE_BLAS:STRING=ON \
    -D TPL_ENABLE_LAPACK:STRING=ON \
    -D TPL_ENABLE_MPI:STRING=ON \
    -D Trilinos_ENABLE_Amesos:STRING=ON \
    -D Trilinos_ENABLE_Amesos2:STRING=ON \
    -D Trilinos_ENABLE_AztecOO:STRING=ON \
    -D Trilinos_ENABLE_Belos:STRING=ON \
    -D Trilinos_ENABLE_Epetra:STRING=ON \
    -D Trilinos_ENABLE_EpetraExt:STRING=ON \
    -D Trilinos_ENABLE_Ifpack:STRING=ON \
    -D Trilinos_ENABLE_ML:STRING=ON \
    -D Trilinos_ENABLE_MueLu:STRING=ON \
    -D Trilinos_ENABLE_Teuchos:STRING=ON \
    -D Trilinos_ENABLE_Triutils:STRING=ON \
    -D Trilinos_ENABLE_Isorropia:STRING=ON \
    -D Trilinos_ENABLE_Zoltan:STRING=ON \
    -D CMAKE_OSX_SYSROOT:PATH=/ \
    ../trilinos.repo


In the same way, you can also specify additional compiler flags, e.g.,
using CXXFLAGS. At least this works fine in all environments I use.
