When I try to compile the 5/20/1999 CVS source of Mozilla for the Motif toolkit (against Lesstif 0.88.1 here on Red Hat Linux 6.0), I get the following compiler errors: nsMotifWidgetFactory.cpp: In

Motif is not one of our target 'platforms'. If you are trying to port to it, then this is part of the work. reassigning back to zuperdee@penguinpowered.com. CC'ing mcafee so he can tell me if I'm full of sh*t.

I'm sorry. I thought it was one of the target platforms... In news://news.mozilla.org/373AF93E.6B556E6B%40cybersight.com, Bruce Mitchener said: -------------------------------------------- There's also some raw Xlib code in the tree, and someone working on support for Photon which is the Windowing system for QNX. > also trying to port it to Qt as well).

My OS is Linux, BTW, in case that helps. > Anybody out there have an answer?? There wasn't anyone working on the Motif code for some time, and it had fallen into a state of bitrot. Brian Ostrom has been checking some fixes in though lately, so maybe someone is resurrecting it? -------------------------------------------- So I guess it's still there, but nobody is really serious about it. If it won't compile, it isn't too big a deal; I've always thought Motif applications looked vomitous compared to GTK+ anyway, but I just thought it might be interesting as a way of seeing how we could push the limits of Lesstif, and maybe help iron out bugs in it, just for fun. I was also wondering because it wouldn't make sense to me to have it there cluttering up the tree if it wasn't actually usable. Unfortunately, I only recently completed some introductory courses in C/C++, but for some reason, I am really intrigued now. Man, I feel like doing something... So, if nobody else is specifically working on this, I am willing to take a stab at trying to fix the Motif port... I cannot guarantee anything though. Is this okay??

Sure it's okay, whatever turns you on! However, I'd also encourage you to consider getting involved in the GTK development, as we really need help there. Thanks!

Turning the priority down to enhancement, since I don't mean to hold anybody else up with this... After all, it is basically now just for my own curiosities, and I know it isn't one of the reference platforms. BTW, whom should I submit the patches to once I have them ready? Shall I just attach them to this bug for somebody to check in?

Actually, I might as well mark this as fixed, since I have now fixed these particular compiler errors (you may verify this by looking at Executor on the SeaMonkey Ports page in Tinderbox if you want). Other problems with the Motif remain, but I am working on these in my spare time, too. So I will mark this as fixed so as to get this off your radar if you want to mark it verified.

marking verified per developer's comments...
