I am trying to call a C routine (which uses C++ libraries) from a Fortran main program. To deal with the name mangling i need to link with a c++ linker. I've done this before, and it worked. But now I keep getting told "Cannot find main". Can't work out what I'm doing differently to before. Can anyone help?
:confused:
How about a clue as to which compiler set you're using?
The fortran routines were compiled with Intel8 (ifort) compiler. And I am trying to link with g++. The only difference before when it worked was I was using Intel 7 instead of 8.
Well that sure is gonna make it tough.
It's hard enough when all the tools come from the same place, then at least there is a change that naming and calling conventions are consistent.
Ever thought of using the G77 Fortran compiler from GNU?
I may try that to see if it works. In the long term I will need to use the Intel8 for speed.
My other suggestion would be to use the 'nm' tool to explore the symbol names which are inside the various object files produced.
Try making a C main() and converting your Fortran program into a function.
