Summary0013379: Toolchain prefix not set correctly for Fortran projects
DescriptionI have a project involving Fortran, C, and C++. I was writing a toolchain file for MinGW so I could compile Windows binaries on my Linux box. I had the following on the top of my CMakeLists.txt:

project(name Fortran C CXX)

In my toolchain file I sat the C, CXX and Fortran compiler, and root path. What I then noticed was that instead of using the AR/RANLIB with the MinGW prefix, it was using the default /usr/bin/[ar/ranlib].

This was solved simply by changing the order in the project line as described above, to instead read:

project(name C CXX Fortran)

(not having Fortran first). See also mail exchange:
http://www.cmake.org/pipermail/cmake/2012-July/051136.html [^]
and attached two toolchain files in:
http://www.cmake.org/pipermail/cmake/2012-July/051152.html [^]

Please ask if something is unclear. I should also add that I do not know the origin of the problem, so for what I know it does not need to be fortran related.
Steps To ReproduceCreate a project with Fortran as the first enabled language
Create a toolchain file which should enable a prefix for additional tools
TagsNo tags attached.

 Alex,

In case you missed it on the ML,
there seems to be a related issue when cross-compiling on Darwin to Windows,
when no language is passed to the project command:

 At least that would help, if not I have to set the language used for each project I use.

 That is the diff at my project on darwin host to cross compile for windows.
The new one works only with patched version of CMakeFindBinUtils.cmake

 Since I have never used Fortran and there were not yet any requests for cross compiling support for Fortran, I think I didn't actually add the cross compiling support for Fortran.
I guess I'll have to have a look at it.

 What is the exact name of the fortran cross compiler executable ?

 In my case the name is i486-mingw32-gfortran

 Can you please check whether it works for you if you use the attached CMakeDetermineFortranCompiler.cmake (i.e. put it in the Modules/ dir of your installed cmake) ?

 Missing file:
CMake Error at /usr/share/cmake-2.8/Modules/CMakeDetermineFortranCompiler.cmake:22 (include):
  include could not find load file:

    /usr/share/cmake-2.8/Modules/CMakeDetermineCompiler.cmake

I don't find this file in git neither..?

 Indeed, this file is only three weeks old, I attached it, maybe it works if you simply put it in the Modules/ directory.

Or you can get the whole FortranCrossCompiling2 from cmake stage and build it yourself:

 Yes, these two files works for me, and sets the correct ar/ranlib it seems. Thank you for fixing! :)
