Title: fs2 unix port
Post by: Kazan on August 07, 2002, 02:20:23 pm

did you merge the unix port from http://www.icculus.org/freespace2/cvsinfo.php initially and are working off that code?

penguin is better equpped to answer that, but the short answer is no.

He had/has basic graphics functionality implemented by the time they released that. That icculus build needs GCC3.x to compile, and no special steps were taken to preserve windows functionality.

I have been following the mailing list, they seem to have windows compatibility working, meaning their client can play with the retail client, butI am not sure about compiling the windows code.

Penguin's was done with compatbility in mind, so I believe he is using that as a reference, but not actually using their code.

It also compiles under gcc 2.x and later, which was something we as a group decided was important (being somewhat unconvinced of the gcc 3.x stability). I think this compatibility was the least of the reasons not to simply use their code, but it wasa reason.

well it runs. i got a plethora of screen shots for you - it would be a task but you can hand-merge their code and ensure windows compatability

Yeah, like I said, he's planning on using that as a reference.

I hear it runs pretty well, actually, big kudos to them. They have also made some headway getting fs1 to work on *nix using the fs2 binary.

sweet.. it's clear that it needs some work, there are hpraical artifacts, it's an unoptimized renderer [i just compiled it in an optimized build so i'll see what that does to my performance], but nothing major

I've play all the way through with the icculus version without anything but a few texture rendering bugs.  I'm qurious if anyone has seen texture bugs under NVIDIA OpenGL drivers instead of Mesa3D (ati radeon 7500).

I've started trying some of the 3rd party missions.

My attempts with the Penguin version segfaults at OpenGL initialization (both gcc 3.1  and rh gcc 2.96).  I'm going to try gcc 2.95.3 and see what happens.

It's been a rather low priority for me, unfortunately.  I did want to get a *nix/OpenGL/SDL version going, but got too involved with the other stuff.  I have reached the point where it will compile under both Microsoft Visual Studio 6.0 and gcc 2.95.3.

It is (barely) playable under Linux:

• performance is bad (due to crappy OpenGL coding on my part)
• there are some known bugs in the cfile packages that result in segfaults
• I have had a couple reports of segfaults at SDL init (kieran and others have reported), but I can't reproduce them with my setup, so I have no idea what the problem is.  FWIW I am running the NVIDIA OpenGL on XF86 4.1, RH6.2, GeForce3.
• doubtless there is other broken stuff

I would be very happy if someone else wanted to contribute to this.  I will lend whatever support I can, but as I said, it hasn't been a huge priority for me since icculus got their stuff going.

Regarding the Linux port hosted at icculus.org:

I noticed a mention of graphical glitches, but it's not really fair to the FSSCP people to clutter their forums with bug reports from our version.  If you have something to report, please post it on the bugzilla at icculus.org or send a message to the mailing list.

However I do think it's important to note that the gcc 3.0 dependency was dropped long ago, and that Windows compatibility has always been carefully preserved in our build.

THEY SPEAK :)

Maybe it's time to merge?

It wasn't entirely clear from the mailing list that the windows code was being preserved. Someone actually said "I have not made any special effort" ;)

Anywho, you guys have done a great job, and we fully intend to steal from it :)

Most of the changes posted here are in our CVS, so, obviously feel free to do the same.

We don;t mind the clutter (at least I don't) and it helps the whole learning process if someone else observes things.

But, to theoddone's point, use bugzilla :)  But penguins comments were about his own code ;)

Yes yes yes, this is true... calling my linux port "half-assed" would be a discredit to donkeys everywhere ;)  

You guys have done a fine job, as Inquisitor mentioned, we'd like to use some of your GL code as a reference, at the very least.
