I comment my problem from the begining:
I have some .c, .h and .f (fortran) files. I need to create a dll with them. For it, I use the compaq visual fortran profeesional 6.5 because I have .f files (fortran). All the files compile perfectly. But the problem is linking.
I´ve downloaded the microsoft c++ toolkit for the compiler in c.
I don´t change to visual c++ 6 because it doesn´t compile fortran files, and I need them. I need to create a dll, and it is possible with compaq visual fortran.
The problem continues... :
