ecbuild_find_mpi¶
Find MPI and check if MPI compilers successfully compile C/C++/Fortran.
ecbuild_find_mpi( [ COMPONENTS <component1> [ <component2> ... ] ]
[ REQUIRED ] )
Options¶
- COMPONENTSoptional, defaults to C
list of required languages bindings
- REQUIREDoptional
fail if MPI was not found
Input variables¶
- ECBUILD_FIND_MPIoptional, defaults to TRUE
test C/C++/Fortran MPI compiler wrappers (assume working if FALSE)
Output variables¶
The following CMake variables are set if MPI was found:
MPI_FOUND
MPI_LIBRARY
MPI_EXTRA_LIBRARY
The following CMake variables are set if C bindings were found:
MPI_C_FOUND
MPI_C_COMPILER
MPI_C_COMPILE_FLAGS
MPI_C_INCLUDE_PATH
MPI_C_LIBRARIES
MPI_C_LINK_FLAGS
The following CMake variables are set if C++ bindings were found:
MPI_CXX_FOUND
MPI_CXX_COMPILER
MPI_CXX_COMPILE_FLAGS
MPI_CXX_INCLUDE_PATH
MPI_CXX_LIBRARIES
MPI_CXX_LINK_FLAGS
The following CMake variables are set if Fortran bindings were found:
MPI_Fortran_FOUND
MPI_Fortran_COMPILER
MPI_Fortran_COMPILE_FLAGS
MPI_Fortran_INCLUDE_PATH
MPI_Fortran_LIBRARIES
MPI_Fortran_LINK_FLAGS
ecbuild_enable_mpi¶
Find MPI, add include directories and set compiler flags.
ecbuild_enable_mpi( [ COMPONENTS <component1> [ <component2> ... ] ]
[ REQUIRED ] )
For each MPI language binding found, set the corresponding compiler flags and add the include directories.
See ecbuild_find_mpi
for input and output variables.
Options¶
- COMPONENTSoptional, defaults to C
list of required languages bindings
- REQUIREDoptional
fail if MPI was not found
ecbuild_include_mpi¶
Add MPI include directories and set compiler flags, assuming MPI was found.
For each MPI language binding found, set corresponding compiler flags and
add include directories. ecbuild_find_mpi
must have been called before.
