Re: Running gtk_main in a thread

[Didier Pralon <didier pralon mdeo fr>]

Thank you for your reply.

Yes , I am using your DLLs under cygwin but I am linking their libs with
my code compiled with the -mno-cygwin -mms-bitfields options of GCC(3.1).
So my soft does not use the cygwin runtime.
Excuse me but my testcase is not relevant because i wrote it for cygwin (I
thought it was easier for you to test it) and not for the mingw32
environment. Anyway, the test case doesn't work in either environment. If
I call the main_thread function of the testcase directly from main and not
in a thread, everything works in both cygwin and mingw32 environment.

So I think that my problem is the problem you mentioned as number 2.

I am now trying to compile the gdk and gtk (using microsoft compiler) in
order to put some trace in the code.

Any hints about the functions and the files I should look for?

I really need to have win32 gtk working in a multi-threaded environment.
