* FortranCInterface: Fix PathScale detectionBrad King2010-01-221-0/+1
| | | | | | | PathScale Fortran mangles module symbols as "MYSUB.in.MYMODULE" and also requires "mymodule_" when the module is imported. We cannot provide the symbol with ".in." mangling so we should not provide "mymodule_" because it would duplicate the one in the Fortran-provided object file.
* FortranCInterface: Mangling for Intel on WindowsBrad King2009-10-051-0/+4
| | | | | The Intel Fortran compiler for Windows uses upper-case symbol names with no trailing underscore.
* Convert CMake non-find modules to BSD LicenseBrad King2009-09-281-0/+11
| | | | | | | This adds copyright/license notification blocks CMake's non-find modules. Most of the modules had no notices at all. Some had notices referring to the BSD license already. This commit normalizes existing notices and adds missing notices.
* Teach FortranCInterface about g77 manglingBrad King2009-08-061-0/+1
| | | | | The old GNU g77 Fortran compiler uses the suffix '__' for symbols containing an underscore in their name.
* Sort FortranCInterface global mangling symbolsBrad King2009-08-061-2/+2
| | | | | This just cleans up the list ordering so more entries can be added while keeping everything organized.
* Cleanup FortranCInterface for PGI and GCC 4.2Brad King2009-08-051-6/+6
| | | | | This documents the purpose of the extra my_module_.c and mymodule.c source files, and sorts the symbols.

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.
