Thanks.

I have made a Windows-f90.cmake file which is read instead of the 
default one.
But now it seems that file names are not correctly generated by TRY_COMPILE
in CMakeTestFortranCompiler.cmake.
I can't trap why since the generated files in CMakeFiles/CMakeTmp are
removed too quickly :)


Is there an option of CMake allowing to keep temporary files ?



With 'NMake Makefiles' generator (the one I normally use), the
error is:
====================
Determining if the Fortran compiler works failed with the following output:
    nmake -f CMakeFiles\cmTryCompileExec.dir/build.make /nologo 
-L                  CMakeFiles\cmTryCompileExec.dir\build

CMakeFiles/cmTryCompileExec.dir/testFortranCompiler.obj

@C:\DOCUME~1\Chef\LOCALS~1\Temp\nma00560.
F90: error: Unknown switch: '/cmTryCompileExec.dir'
NMAKE : fatal error U1077: 'C:\PROGRA~1\MICROS~2\DF98\BIN\F90.EXE' :

Stop.
NMAKE : fatal error U1077: '"C:\Program Files\Microsoft Visual 
Studio\VC98\BIN\nmake.exe"' : return code '0x2'
Stop.
====================

Is seems that path of file contains '/' instead of '\' (and compiler 
doesn't like at all

With 'Visual Studio 6' generator, it works or not (but I don't know 
why). When
an error occurs the message is:
====================
Determining if the Fortran compiler works failed with the following output:
--------------------Configuration: cmTryCompileExec - Win32 
Debug--------------------
Building Fortran object testFortranCompiler.obj
C:develBRATCMakeFilesCMakeTmptestFortranCompiler.f

... file is 'C:develBRATCMakeFilesCMakeTmptestFortranCompiler.f'
Error executing c:\windows\system32\cmd.exe.
 
cmTryCompileExec.exe - 1 error(s), 0 warning(s)
==================== 

It seems that no directory separator at all is generated... strange.


Note: I can send the Windows-f90.cmake file (I did not include it
because of it's size).
