DLLEXPORT use in Intel Fortran within Modules

[Mohammad_K_]

Hello,

I want to export the subroutines in the generated DLL library. I am using the following statements in the module but when checking the DLL using dumpbin the subroutines, i find that no subroutine symbols are exported. What am I doing wrong?

MODULE moduleName
CONTAINS
SUBROUTINE Y(X,Z)

!DEC$ ATTRIBUTES DLLEXPORT,ALIAS:"DLL_Y" :: Y

....

END SUBROUTINE

SUBROUTINE Q(A,B)

!DEC$ ATTRIBUTES DLLEXPORT,ALIAS:"DLL_Q" :: Q

....

END SUBROUTINE

END MODULE

Works ok for me - perhaps your actual code isn't exactly like what you paraphrased?

E:\Projects>type t.f90
MODULE moduleName
CONTAINS
SUBROUTINE Y(X,Z)

!DEC$ ATTRIBUTES DLLEXPORT,ALIAS:"DLL_Y" :: Y

!....

END SUBROUTINE

SUBROUTINE Q(A,B)

!DEC$ ATTRIBUTES DLLEXPORT,ALIAS:"DLL_Q" :: Q

!....

END SUBROUTINE

END MODULE

Steve,

The code is not exactly like what I posted. One notable difference is that the project has two modules instead of one. Also I compiled from with MSVS 2012 IDE and not from command prompt. The otherthing is that you are using an export flag in dumpbin, so perhaps they are exported after all. Let me check and get back.

Thanks,

Mohammad
