need help using calling C library in Visual Studio

Hi,

I am new to Intel Fortran and VS and I would appreciate if you could help me...

I need to use this mUMFPACK module for Fortran, which seems to require library written in C. In my mac I am able 

to install suitesparse and compile the module umfpack.f90 from the command line. However, I would like to make it work

on VS my Windows computer as well...

I found this option https://github.com/jlblancoc/suitesparse-metis-for-windows followed all the steps to built suitesparse.

Now, what I need to do is to use the mUMFPACK module for Fortran. Here is what I did

  1. On the build/SuiteSparse/SuiteSparse.sln that is produced by Cmake I added a project MAIN with 2 files: umf_test.f90 (attached) which calls the module umfpack.f90 and the module itself.
  2. On the umfpack.f90 file I add the command INCLUDE 'umfpack.h'.
  3. Right-click the executable Fortran MAIN project and select Dependencies to set the executable project as dependent on the umfpack project

When I try to build it, though, I get the following error. I tried it in the Intel 64 Visual Studio 2015 environment command line as well, but I am even less familiar with that...

Are these steps correct? If so, what am I missing?

Compiling with Intel(R) Visual Fortran Compiler 17.0.0.109 [IA-32]...

umfpack.h is a C/C++ header

umfpack.h is a C/C++ header file. You can't use this in Fortran source.

Looking at the UMFPACK user guide it seems that calling this from Fortran requires some effort and it makes a lot of assumptions about how Fortran compilers do calls and argument passing. It doesn't seem like something you can just grab and start using without digging in to the implementation and making sure the interfaces work for you.
