I am trying to write a GUI Extension for POV-Ray version 3.01. I am
using VC++ 5.0 on a WinNT 4.0 machine. I started a new Win32 dll
project and added guidemo.c to the project. I compiled and built the
project without problem. I added the path to my .pge file in
pvengine.ini. Now when I run POV-Ray, I get the following message:
Could not get Init address for GUI Extension DLL....
I believe the problem lies with the function PovGuiExtensionGetPointers
in guidemo.c. I made no changes to the original guidemo.c source code
for this function.
Can anyone offer any pointers? (pun intended)

Problem solved. VC++ 5.0 doesn't support __export, so you need to write
a .DEF file (and use the associated command line switch) to explicitly
export the PovGuiExtensionGetPointers function. You can use the dumpbin
utility to see exactly which functions are exported from a DLL.

However, VC++ 5.0 does support __declspec(dllexport) which does the same
thing.
