I am having problems adding a FTN95 Fortran library to my Visual C Project using visual studio. The C project is for win32, not .NET. I am compiling my C project as C, not cpp, and I am using the MS C compiler that comes with VS2010.

My FTN95 library contains one top level function that takes no arguments that I believe can be found by the C linker, as I have selected Export All in the FTN95 library project.

It looks to me that I may also need to include a fortran run time library or something in my Visual C project, instead of just the code library. But I can not find any reference to having to do this. The code library also uses a module, if that makes a difference.

Any help on what I may need to do will be appreciated. .

I get the following errors:

You will need to reference salflibc.dll.

However, this will probably not solve all of the issues and you should consider using SCC as your C compiler. Then everything will link together by using SLINK.

Hi Paul
Thanks for your quick response. I did try adding the static library salflibc.lib. However I then got the error message saying that printf etc had been redefined. I expect in a clash with libc.lib from MS. Is there anything I can do about this, or is this why you say to use SCC?

Is there a way to still use the VS project, but use SCC instead ? Or is the only option Plato or a Makefile ?

Thanks

salflibc.lib is a combined static and import library that is used by SLINK to resolve external functions that are accessed at runtime from salflibc.dll.

There is probably a way to use the Microsoft compiler but I don't know how to do this and this approach is not supported by Silverfrost. Basically you will need to find out how to set the application's entry point _SALFStartup.

You may be able to use SCC from Visual Studio, however, Plato is very much like Visual Studio and is configured to handle FTN95, SCC and SLINK in a seamless way.
