Rewrite FortranCInterface module This is a new FortranCInterface.cmake module to replace the previous prototype. All module support files lie in a FortranCInterface directory next to it. This module uses a new approach to detect Fortran symbol mangling. We build a single test project which defines symbols in a Fortran library (one per object-file) and calls them from a Fortran executable. The executable links to a C library which defines symbols encoding all known manglings (one per object-file). The C library falls back to the Fortran library for symbols it cannot provide. Therefore the executable will always link, but prefers the C-implemented symbols when they match. These symbols store string literals of the form INFO:symbol[<name>] so we can parse them out of the executable. This module also provides a simpler interface. It always detects the mangling as soon as it is included. A single macro is provided to generate mangling macros and optionally pre-mangled symbols.

FortranCInterface: Work around mingw32-make trouble with parens The mingw32-make tool does not handle parenthesis in the path to a source file consistently. When CMake is installed in a typical location like "c:\Program Files (x86)\CMake 2.8\" the mingw32-make tool fails on the FortranCInterface detection project sometimes with errors like >mingw32-make -f CMakeFiles\myfort.dir\build.make CMakeFiles/myfort.dir/my_module.f90.obj mingw32-make: *** No rule to make target `x86)/CMake 2.8/share/cmake-2.8/Modules/FortranCInterface/my_module.f90)', needed by `CMakeFiles/myfort.dir/my_module.f90.obj'. Stop. due to parens in the path to the FortranCInterface source directory. However, the behavior varies with the file name of build.make: >copy CMakeFiles\myfort.dir\build.make CMakeFiles\myfort.dir\build2.make >mingw32-make -f CMakeFiles\myfort.dir\build2.make CMakeFiles/myfort.dir/my_module.f90.obj [ 3%] Building Fortran object CMakeFiles/myfort.dir/my_module.f90.obj Tested with >mingw32-make -v GNU Make 3.82 Built for i386-pc-mingw32 Work around the problem by copying the whole FortranCInterface source directory in to the project build tree.

The executable links to a C library which defines symbols encoding all known manglings (one per object-file). The C library falls back to the Fortran library for symbols it cannot provide. Therefore the executable will always link, but prefers the C-implemented symbols when they match. These symbols store string literals of the form INFO:symbol[<name>] so we can parse them out of the executable. This module also provides a simpler interface. It always detects the mangling as soon as it is included. A single macro is provided to generate mangling macros and optionally pre-mangled symbols.
