Cooperation between Odin & Wine - wine-devel

26 Dec 2001


      Hi,
As some of you might remember I'm the lead developer of the Odin project. (project
for OS/2 with the same goals as Wine). Odin is partly based on Wine code. The
core dlls (gdi32, user32, kernel32) + some special dlls (winmm, directx, winsock)
use some Wine code, but is basically incompatible with Wine for obvious reasons.
Most of the remaining dlls are based entirely on Wine code.
The last few years there has been little cooperation between both projects for several reasons.
One of them is that we have far fewer active developers and cooperation sometimes proved to be
difficult.  Some source files of the two project had grown apart since changes were never merged back into Wine.
Now, I'm trying to change this situation, but am wondering how to proceed. I can post bug fixes to this list, but
it will be difficult for me to actually test these changes in Wine itself. (too time consuming)
Posting diff files is not always possible due to the major differences between source files.
Merging changes from Wine into our source tree is no problem. We can do that ourselves. However, it would
be nice if compiler incompatibilites (we use IBM VisualAge C++, not GCC) could be resolved. There aren't
many, but the IBM compiler is not always as flexible as GCC and of course doesn't understand any GCC extensions.
It would be a big help if incompatible code could be changed. Switching compilers is not an option for us.
I can post a (small) list of changes we had to make.
The license of our project is not compatible with Wine, but the dlls that are largely based on Wine (such as 
comctl32, shell32, ole) are an exception to the project license. The sources of those dlls are released under the
Wine license. 
In case there is ever interest in the other sources, then you can just ask me. I'd be happy to 'donate' them to 
Wine.
For more information about Odin you can visit http://odin.netlabs.org (some information is outdated though).
There you can find out where to download the sources (cvs).
The next post from me will contains some patches for bugs in Wine that I've recently found.
