    Using a Fortran .lib

    Hi,

    Someone gave me a Fortran .lib file which contain functions I need to use in a C++ program.

    How should I do that ?

    Let's say for instance I want to call a function called "SquareRoot".

    (I'm using Eclipse (Wascana) under windows, with GNU C++ compiler)

    Cheers.

    This page has the usual method for *nix systems. That may or may not work for you, depending on how the .lib file was made.

    And was the Fortran library compiled using the GNU Fortran compiler?
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Unfortunately, I can't be sure about any oh those right now.
    Isn't possible to use them without knowing how they were made ?

    I'd assume it's F77.

    Possibly, but it certainly raises the bar a lot.

    Calling conventions, symbol decorations etc all have to be "hacked" in some way if all the libraries are not compiled with the same tool chain.
