[omniORB] Weird issue running omniORB under wine

[Barry Roberts]

I'll try the SVN version first.  Then I'll tweak SocketCollection.cc if I can still reproduce the problem.

Thanks!

Barry

Well, it's possible that it is an omniORB problem. Can you try with the
latest SVN version?  There have been a few fixes in that area of the
code that I don't think will be relevant, but it's worth using the
latest version to be sure.

My guess is that the problem comes down to the strange way Windows
fd_sets work. Wine is possibly not using exactly the same semantics,
which will be a problem for omniORB because it relies on implementation
details for performance reasons. There is code around line 907 or
SocketCollection.cc that reaches in to the fd_set array and sets it
directly. Perhaps you could try changing it to use the FD_SET macro?
Search for other uses of fd_array in that file and change them to use
FD_SET / FD_CLR too. I don't know if that will help, but it's worth a
go.

Cheers,

Duncan.
