Gfortran : fortran 90 not supported

[Jesús Garicano Mena]

Hi Thomas,

Thanks for your answer.

For the simple program, doing this:

>> gfortran -ff90 hiWorld.f90

I get :
f951: error: unrecognized command line option "-ff90"

As for the complete project, I get a cmake error, tied to the compiler  :
....

-- Check for working Fortran compiler: /usr/bin/gfortran
-- Check for working Fortran compiler: /usr/bin/gfortran  -- broken
CMake Error at /usr/share/cmake-2.8/Modules/CMakeTestFortranCompiler.cmake:40
(MESSAGE):
  The Fortran compiler "/usr/bin/gfortran" is not able to compile a simple
  test program.

  It fails with the following output:
