pgicpp link with fortran library?

Hi,

I am calling fortran library(ARPACK, a sparse matrix library) from c++. Does anyone know how to link the C++ code with the fortran libary? Is there some options in pgcpp I need specify?

Thank you!!!

Hi Yonggang,

Chapter 11 of the PGI User’s Guide (See: http://www.pgroup.com/doc/pgiug.pdf) details inter-language calling, including C++ calling Fortran.

Basically, you need to an underscore ("_") to the end of the Fortran function name in your C++ code and pass all your variables by reference. You also need to match your data types correctly depending upon if your compiling in 32 or 64-bits.

Hope this helps,
Mat
