[CMake] linux cmake with intel compiler

[Tim Gallagher]

There's two ways we do it. If you are starting with a clean cache (first time you run ccmake), if you do:

CC=icc FC=ifort ccmake /path/to/source

It will set it up using Intel compilers.

We also do:

include(CMakeForceCompiler)
CMAKE_FORCE_C_COMPILER(icc "Intel C Compiler")
CMAKE_FORCE_CXX_COMPILER(icpc "Intel C++ Compiler")
CMAKE_FORCE_Fortran_COMPILER(ifort "Intel Fortran Compiler")

Lastly, when using the Intel compiler, we add:

if(${CMAKE_Fortran_COMPILER_ID} STREQUAL "Intel")
   if(NOT CMAKE_Fortran_FLAGS_RELEASE)
      set(CMAKE_Fortran_FLAGS_RELEASE "-O2 -xhost" CACHE STRING "" FORCE)
   endif()
  set(CMAKE_Fortran_FLAGS_DEBUG
      "${CMAKE_Fortran_FLAGS_DEBUG} -check noarg_temp_created -C -traceback" CA\
CHE STRING "" FORCE)
  set(CMAKE_Fortran_FLAGS_DEBUGHEAVY
      "${CMAKE_Fortran_FLAGS_DEBUG} -check noarg_temp_created -fpe0 -warn align\
ments -warn declarations -warn general -warn interfaces -warn truncated_source \
-warn uncalled -warn uninitialized -warn usage -common_args -warn unused -fp-st\
ack-check -check bounds -check uninit -check format" CACHE STRING "" FORCE)
   mark_as_advanced(CMAKE_Fortran_FLAGS_DEBUGHEAVY)
endif()

Hope that helps,

Tim

What do you mean by "no-effect" ?
gcc is found and used?

$ source /opt/intel/Compiler/11.1/064/bin/iccvars.sh
$ CC=/path/to/icc CXX=/path/to/icpc cmake /path/to/source

works for me on Linux for several project using CMake including CMake itself?
Test done with CMake 2.8.3.

Which version of CMake are you using?

> Call of intel compiler environment - no effect too..

Same question what does "no effect" mean ?
