Hi,
I have a problem trying to prepare a large simulation package, using
mixed F90 and C++ routines, to compile and build under GCC (g++, and
gfortran). The problem is I have a C++ function: Gauss() which is
called from an F90 routine:
x=gauss()
This package was made able to build under the Intel fortran compiler by
adding to the fortran file the Intel compile directive:
!DEC$ ATTRIBUTES ALIAS:'Gauss' :: gauss
I attempted to build this program using GCC where for F90 code the
gfortran compiler option -fno-underscoring was used.
Presently my fortran routine won't build. It gets the error:
485: undefined reference to `gauss'
So, my question is, is there a way in GCC to enable the linker to find
the C++ 'Gauss' method?
Thanks,
