I have encountered trouble with a 32-bit application developed with ifort. I have an executable (created in Fortran) that calls a dll (created in C++). The specific error I get at run-time is:
forrtl: severe (157): Program Exception - access violation
I have a feeling my problem spawns from how I call the DLL, or at least something to do with the !DEC$ attributes. I can sucessfully compile and run the program in linux using another compiler, but I am encoutering this trouble when porting it to windows. I call the DLL using these directives:
SUBROUTINE MAP_C2F_CopyInput( InputData, ErrStat, ErrMsg )
TYPE(MAP_inputtype), INTENT(INOUT) :: InputData
INTEGER(IntKi), INTENT( OUT) :: ErrStat
CHARACTER(*), INTENT( OUT) :: ErrMsg
INTEGER(IntKi) :: i
ErrStat = ErrID_None
ErrMsg = ""
IF ( ALLOCATED( InputData%X ) ) THEN
i1 = SIZE(InputData%X,1)
CALL MAP_C2F_Input_X(InputData%C_obj,InputData%X ,i1)
!DEC$ ATTRIBUTES STDCALL::MAP_C2F_Input_X
!DEC$ ATTRIBUTES ALIAS:'_map_c2f_input_x_@12'::MAP_C2F_Input_X
!DEC$ ATTRIBUTES DLLIMPORT::MAP_C2F_Input_X
END SUNROUTINE ...
Any help pointing out to what I've done wrong would be appreciated.
