Depending on what you mean by "a shared library that loads a native Win32 DLL
using libwine", I have done this or something similar. I built a shared library
that loaded a DLL and exported the DLL functions so that they could be executed
from native C code outside of the shared library. I did this with a toy DLL
(Petzold's book EdrTest/EdrLib example Chap 21 in my version). I am currently
writing the HOWTO-winelib documentation (not in any source release but in
current cvs). I was planning to write the DLL section this weekend and include
a simple example of loading a DLL within a shared library. Can you wait that
long? I have to work at a real job during the week and do wine on weekends. I
would prefer not to give the EdrTest/EdrLib example over the web, since it
involves code under MS copyright (they have more lawyers than I have lawyers).
If you have a copy of Petzold, I can send you the other files and you can
probably figure the rest out.
When I got my DLL working, I did not get the same errors that you are getting.
Our minds must be orthogonal, we make completely different errors. :^)
I did not call MAIN_WineInit() or PROCESS_Init() in my shared library. The
initialization code was created by the spec file for the executable and the
spec file for the shared library.
Reply by private e-mail giving more details of what you are trying to do and I
may be able to help more (tomorrow).
