From some of the MinGW sites: “ The MinGW basic runtime system, which is basically the glue to the underlying operating system, is completely in the public domain. The runtime system includes MinGW headers (such as stdio.h), libraries (such as libmingw32.a) and import libraries for CRTDLL/MSVCRT. W32API, which consists of the headers and import libraries related to WIN32 API access, is released under copyright . The copyright agreement states no restrictions are placed on programs or object files compiled with the library. Mingw provides access to the Win32 API. Theoretically, if you own the MFC source code you could build MFC libraries for Mingw. No one's tried this so far. If anyone does successfully accomplish it, please say so and it will be added to this document… “ MinGW is the common denominator to link Fortran to C/C++. From what I’ve seen, Cygwin can be used on windows machines as well. For example: g77 -c test.f 2 g++ -o test test.cpp test.o g77 will compile and assemble the Fortran source file test.f into the object file test.o g++ will compile and assemble the C++ source test.cpp and link it to the Fortran object file test.o and create the test.exe executable. I haven’t come across how this can be done with VC++. To the contrary, not being able to do this sort of thing is one of the driving forces behind multi language compiler utilities such as MinGW.
