GCC Produced Dlls Not Compatible with Intel Visual Fortran?

Question

I used gcc to compile a few fortran source files into *.lib and *.dll on Windows platform, using the latest version of mingw . The gcc used is version 3. The result of the output is arpack_win32.dll, blas_win32.dll and lapack_win32.dll.

I then want to compile sssimp.f against the arpack_win32.dll, blas_win32.dll and lapack_win32.dll using Intel visual fortran compiler for Windows, because sssimp.f uses those dlls. But I got the impression ( from Intel support forum) that this is not possible.

Is my impression correct? Or is it that as long as I can produce the underlying libs and dlls ( no matter in which compiler and how old it is), I can use them as my base libs and dlls, and I can link to them from any, modern or old, compiler?

Answer 1

g77 uses a different ABI than IVF, yes. So unless IVF has some g77/f2c compatibility option it's not going to work.

The easiest solution for you is probably to use IVF to compile the libraries too.

Answer 2

As already pointed out, mixing compilers with different calling conventions is likely to be very difficult.

That answer on the Intel Forum pointed out a version of arpack translated to Fortran 90 -- http://people.sc.fsu.edu/~burkardt/f_src/arpack/arpack.html -- can you use that? Also see http://people.sc.fsu.edu/~burkardt/f_src/lapack/lapack.html and http://people.sc.fsu.edu/~burkardt/f_src/blas1_s/blas1_s.html

Or Intel Visual Fortran should be able to compile Fortran 77 using suitable compiler options. What language constructs is it rejecting?
