The output variable +dnl FLIBS is set to these flags. +dnl +dnl This macro is intended to be used in those situations when it is +dnl necessary to mix, e.g. C++ and Fortran 77, source code into a single +dnl program or shared library. +dnl +dnl For example, if object files from a C++ and Fortran 77 compiler must +dnl be linked together, then the C++ compiler/linker must be used for +dnl linking (since special C++-ish things need to happen at link time +dnl like calling global constructors, instantiating templates, enabling +dnl exception support, etc.). +dnl +dnl However, the Fortran 77 intrinsic and run-time libraries must be +dnl linked in as well, but the C++ compiler/linker doesn't know how to +dnl add these Fortran 77 libraries. Hence, the macro +dnl `AC_F77_LIBRARY_LDFLAGS' was created to determine these Fortran 77 +dnl libraries. +dnl +dnl This macro was packaged in its current form by Matthew D. Langston +dnl . However, nearly all of this macro +dnl came from the `OCTAVE_FLIBS' macro in `octave-2.0.13/aclocal.m4', +dnl and full credit should go to John W. Eaton for writing this +dnl extremely useful macro.
