I don't know yet, it was just my observation, and I wanted to tell you about it. I need to check it, and ISTR that something with threads is ... em ... suboptimal in configure. But this is not likely to happen before the weekend. >> Side note: to get rid of (gcc 4.5.2) dll dependencies I also >> configured with "LDFLAGS=-static", and now I don't have any >> non-Windows dependencies again.

This is just a workaround I found to work for me. I didn't see any side effects, but didn't look for it intensively. I'm in a process to evaluate the new MinGW/MSYS (with gcc 4.5.2) for our commercial app, so that we can get rid of using Cygwin as our build tool. I'll keep you and the FLTK folks informed whatever I find, and I'll try to put this into configure, of course. It should work OOTB. <OT> We must add openssl, and I believe that it would be difficult to configure openssl under Cygwin for a native Windows build, because I had similar problems with another lib used earlier. It worked with the Cygwin dll, though, and it didn't work with the MSYS openssl lib for some reason I don't know yet (and maybe never will). Did you or anybody else here compile openssl (1.0.0c) with MinGW successfully? Any known problems and solutions? </OT> Albrecht _______________________________________________ fltk mailing list fltk@easysw.com http://lists.easysw.com/mailman/listinfo/fltk
