trying to build a DLL on Windows 7 gcc using 3rd party libraries

  tried both stdcall and cdecl - both fail.

  that is possible and I could try that

  thanks, I will try those a little later today

>Are those libraries available somewhere so that we can test with them?

The libraries and include files defining the failing routines are part of the FREE Firebird 2.5 distribution.

I have built a minimal version of my code which calls the two routines needed in the libraries, included a builddll.bat file which is how I TRY to build this; included the two firebird include files AND the two firebird libaries they point at. They are all attached for your viewing.

I will continue trying the two microsoft programs you suggested (if I have them, or try to download).

If you have these tools and can easily see some trivial changes to the "EXPORT" pre-compiler macro that I use, I would be eternally grateful.
