[CMake] CMake and Absoft Fortran compilers

Wed Sep 22 14:53:40 EDT 2010

Do you know how to compile for Fortran in general? I don't know the Absoft compiler, but I've used some others.

First off you need to enable Fortran language. This you can do by e.g.
PROJECT(<projectname> Fortran CXX C) where you after the project name gives a list of the languages you use in your project.

Next you can enable the compiler of choice with (replace g95 with the binary of your compiler)
SET(CMAKE_Fortran_COMPILER g95)
You can set this when you call cmake instead, like this
cmake -DCMAKE_Fortran_COMPILER=g95 <path>

Then you can continue setting Fortran specific flags based on compiler:
  if (CMAKE_Fortran_COMPILER MATCHES "gfortran")
   set (CMAKE_Fortran_FLAGS_RELEASE " -g -funroll-loops -fno-range-check -fno-f2c -O2 ")
   set (CMAKE_Fortran_FLAGS_DEBUG   " -fno-f2c -O0 -g ")
   set (CMAKE_Fortran_LINK_FLAGS   "${CMAKE_Fortran_LINK_FLAGS} -static ")
 elseif (CMAKE_Fortran_COMPILER_ID STREQUAL "Intel")
...
 endif (CMAKE_Fortran_COMPILER MATCHES "gfortran")

I hope this helps, not quite sure this was what you asked for? By the way, you need CMake 2.6.x or newer I believe, fortran support is quite limited (or non-existent?) in earlier versions.

Best Regards
