Why does my C/C++ compile/link fail with missing pgf77 or pgf90 symbols?
One of the libraries that you are using may have been compiled with Fortran in such a way that Fortran-specific symbols remain in the .a file. If this happens, then a compile/link with cc or CC will report unresolved symbols such as __pgf90_compiled. To include the necessary libraries to resolve the missing symbols, add -pgf90libs to your cc/CC compile/link line. There is a similar option, -pgf77libs, that should be used if the missing symbols are Fortran 77 and not Fortran 90.
