FortranFileStream is a basic attempt at a class that uses Fortran file units to read in data, but with a C++ stream syntax.
Some would say that this is a mad idea, but this is useful in the world of cross compiling Fortran and C++. I specifically needed it because I was partially rewriting a Fortran library in C++. Such I needed to do some C++ reading on the same file that the fortran needed to read. What's more I wanted to maintain C++ convention and so we have FortranFileStream.
A few notes:
The current implementation is compiler dependent. It is written using the autoconf macro FC_FUNC, however as the project is too small to warrant autoconf I have provided a version that works on MY system.
The method of passing strings as arguments to Fortran Functions also differs between compilers, so extra functionality may be needed here.
Currently we only support the reading of files, but the principles used (leveraging Fortran's "stream-like" read statements) should extend fairly well to writing files.
Simply use the given Makefile to build the Demo program. In terms of linking your own stuff to it I suggest that you use it as drop in code. Renaming the namespace and providing a real FC_FUNC from autoconf.
