It seems like the DLLEXPORT attribute, when applied to data, is broken in v6.6a. Consider the following:
The following is used to create a DLL and the module M_DLL.
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
module M_DLL
integer (4) Hat
!DEC$ ATTRIBUTES DLLEXPORT :: Hat
end module
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
A program can then USE the module and link to the DLL:
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
program Test
use M_DLL
Hat = 1
end
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Under CVF6.5.0 this compiles and links OK.
Under CVF6.6A, things compile OK, but generate a link error as the program has interpreted 'Hat' as _M_DLL_mp_Hat, whereas the DLL contains M_DLL_mp_Hat. Comparing with the behaviour under 6.5.0, the USE of the module is not being handled correctly.
Is there a cure for this problem? I have not tried v6.6 yet, but can't go back to 6.5 for the main work I am doing...
