D2X-W32 Linux port

Kirby · Post by **Kirby** » Wed Nov 30, 2005 4:49 pm

just noticed a serious bug during gameplay:

Whenever you fire you primary or secondary weapon, the weapon/missle doesn't move...it just draws itself in front of the ship, and it doesn't move. After about 10 seconds, the laser or missle disappears. You can even fly around the missles and reenact a scene from the matrix (but that's not the point)....also, not all area experience this problem. Sometimes the weapons do shoot like they suppose to, but most of the time they don't

This is probably due to the vector calculations (vec_mag_quick I believe). One of the usages (vec_dist_quick?) was changed over, but I had to change both over for the OS X port. Perhaps it should be both for Linux as well.

Kirby seems not to have the most recent source code. That bug has been fixed in 1.5.27.

you mean 1.5.28

one serious bug down...one to go: The robots are hyperactive when it comes to their movements. One second I'm alone in a hallway, and the next second I get rammed a thousand times by one of those hornet robots (for a second there, I almost typed horney :p )

Also (just introduced with 1.5.28 )...when I try to quit, KDE literally locks up....can't do a CTRL+ALT+ESC or a CTRL+ALT+Backspace....I have to reset every time now.

deidel ... this is what i was talking abot on linux forums ... 1.5.27 guidebot smokes crack and does speed and robots seem to be all sorts of incongruent

Hm. I had found a vector math function that works on Win32 not working on Linux and Mac OS X, so I had replaced a call to it by a function that does what it's supposed to do.

After your continuous (justified) complaints, I have now investigated further into the matter and found that the broken function is called at several other places.

A quick fix for you is to open maths/vecmat.h, search for "fix_vec_mag_quick" and replace the non-WIN32 branch of the function with the following (yellow) code:

maths/vecmat.c wrote:fix vm_vec_mag_quick (fix a, fix b, fix c)
#ifdef _WIN32
_asm {
...
}
#else
vms_vector v = {a,b,c};
return vm_vec_mag (&v);
#endif
}

I will post a source update in the next few minutes as well.

I am really asking myself why in all the earth this works on Win32, but not on Linux (even with comparable hardware), or on Mac OS X. Probably a compiler problem (different code generation). The assembly code I have written for the Win32 version is the exact equivalent of the C code for the other OS's.

very nice....game is perfect now

now the only problem left is the lockup when quitting (either from the main menu option, or the window's X button) Upgraded to KDE 3.5 and the latest source code of D2x-XL didn't fix it...

btw...KDE 3.5 is freakin' sweet

Diedel · Post by **Diedel** » Thu Dec 01, 2005 2:18 pm

hrmpf ... no lockup with Gnome ...

Kirby · Post by **Kirby** » Thu Dec 01, 2005 5:20 pm

damn....

It must be something you did between the 1.5.27 and 1.5.28 releases.....cause it was quitting fine before then

Diedel · Post by **Diedel** » Thu Dec 01, 2005 6:31 pm

Maybe kaelan did it.

1. appreciate the work you are doing.

ok, now here is my current issue. i just compiled your new source (1.5.29), although i have not seen so many WARNINGs during a make in my life, it finished and i was on my way back in. menus work fine, but when i get into a game the screen blacks and the monitor clicks as if not syncing. this wasn't a problem before. any ideas?

*edit* front screen says version 1.5.28. also, i have sound, and input works (i can hear myself shoot

)

Diedel · Post by **Diedel** » Fri Dec 02, 2005 3:12 am

Linux is not yet at 1.5.29. You'd need to check out the source code from the SVN to get up-to-date source code. I will check this and come back to you later.

yeah... like i said in the edit it is 1.5.28, i was going by the header top of the page. i will check out the svn tonight when i get home from work and let you know. if you can take a poke at it too i would appreciate it, 1.5.27 looked great... the robots were just psychotic.

Diedel · Post by **Diedel** » Fri Dec 02, 2005 1:35 pm

No problems here. If you have a ~/.d2x-xl, put a semicolon in front of the fullscreen option and see whether the program works in windowed mode.

fyrephlie · Post by **fyrephlie** » Sat Dec 03, 2005 1:47 am

running it windows helped me figure something out. windowed it bounces back and forth between 1280x1024 and a much smaller automap which is one of my 'cockpit windows', this is the case with every resolution i run. if i switch pilots and don't use the map window i have no problems, if i switch (F3) to the widescreen mode, it runs fine. so it appears that for me it is the map windows. any ideas on this one???

Diedel · Post by **Diedel** » Sat Dec 03, 2005 6:21 am

Yeah, your gfx driver.

fyrephlie · Post by **fyrephlie** » Sat Dec 03, 2005 4:59 pm

so you dont have the same problem running the automap in a cockpit window?

it seems odd since this is something new, this worked find previously.

Diedel · Post by **Diedel** » Sat Dec 03, 2005 7:23 pm

Actually, I can't tell until monday.

fyrephlie · Post by **fyrephlie** » Sat Dec 03, 2005 10:28 pm

well until then ... i will just play without the automap in the cockpit windows, seems like a pretty small thing. im not about do go digging through driver archives to find an older driver just yet, i wanna hear for sure that no one else is having trouble, espcecially since this wasnt a problem before the last update.

Diedel · Post by **Diedel** » Sun Dec 04, 2005 2:38 pm

If your drivers are up-to-date, don't bother changing them. I find this pretty amazing though, as I wouldn't know of any recent changes to the OpenGL code.

fyrephlie · Post by **fyrephlie** » Sun Dec 04, 2005 5:46 pm

yeah ... well i am using the same nvidia drivers ... 7676, and nothing about this system has changed between your builds.

i am baffled by it as well, but i will continue to wait until i find out if you have any issues with running the automap in a cockpit window.

it is strange.

Diedel · Post by **Diedel** » Mon Dec 05, 2005 5:25 am

No problems here (v1.5.33 currently) with openSUSE 10. Low end NVidia gfx card.

fyrephlie · Post by **fyrephlie** » Mon Dec 05, 2005 11:14 am

well damn... time to start messing around. i have 1.5.30, but i get 1.5.33 and see what happens. then i will start messing around with gl libraries. but man ... i am really confused why it worked... then it didn't lol.
worst cast scenario is that i dont get to use that automap feature.

(i dont suppose there is a way for you to add the ability to change which cockpit windows you are using in the options menu...)

Diedel · Post by **Diedel** » Mon Dec 05, 2005 12:16 pm

You can toggle through all cockpit window types with Shift+F2 and Shift+F3 (left/right window).

fyrephlie · Post by **fyrephlie** » Mon Dec 05, 2005 12:37 pm

except when experiencing the problems that i am with said cockpit windows. shift+f2 only recognizes f2... or shift... but never both

Diedel · Post by **Diedel** » Mon Dec 05, 2005 3:30 pm

This works for me on my Linux box (openSUSE 10.0). You do have SDL 1.2.8-8 installed?

yup... how do you think i got it installed in the first place.

with the new Linux 1.5.34 release, my freezing problems just got a hell of alot worse....

Linux freezes now on startup of d2x-xl (before the intro movie even plays)...of course, the only way to get by now is to reset my machine.

what's going on here??

u can't kill x? (ctrl-alt-backspace by default)

linux normally doesnt lock up... its the x server / window manager. just a suggestion.

Kirby · Post by **Kirby** » Tue Dec 06, 2005 8:16 am

correct....can't kill X, can't switch between different sessions. Only thing I can do is restart

There's little I can do on my part....I could recompile xorg and update to the latest ATi drivers (ugh...ATi). And if that fails, I could try compiling the debug version of d2x-xl again, and hopefully an error prints out before the freeze....but other than that, I dunno.... :/

Diedel · Post by **Diedel** » Tue Dec 06, 2005 8:47 am

Get v1.5.37 first, just updated it.

I have none of the problems described here with d2x-xl on Linux, so unfortunately I cannot help you here.

fyrephlie · Post by **fyrephlie** » Wed Dec 07, 2005 1:56 am

1.5.37

alright, here is the problem now. everything copiles just fine, but when running the executable binary, the d2x-xl window opens for a moment then immediatly closes without an error message (exactly as it did when i had the game data in the wrong directory before). since the game data hasn't moved, i am wondering if you know why this would be?

sh autogen.sh
./configure --enable-release=yes
make
rename d2x-gl d2x-xl
strip ./d2x-xl
cp ./d2x-xl /usr/local/bin
cp ./d2x-xl /usr/local/share/d2x-xl
d2x-xl

seems i just making all sorts of backwards progress here, everything worked great at first, then you updated and the robots went crazy, then you updated and my automap cockpit window went crazy, now i can't get the damn thing to run... lol ... i should quite while i was behind.

please help!

(is the current executable on your site 1.5.37?)

Diedel · Post by **Diedel** » Wed Dec 07, 2005 3:56 am

Usually this happens when d2x-xl doesn't find something ... I will check this again.

Current Linux binary is 1.5.37 (binaries are always sync'd with source).

Edit: d2x-xl linux doesn't find the data files if they're in the D2 main and not the data subfolder. Grrrr. Everytime I fix this for one OS, it fails on another.

fyrephlie · Post by **fyrephlie** » Wed Dec 07, 2005 12:17 pm

hmm... all the data is in its respective directories, not in the main... i did use a script to rename all the files as lowercase... out of habit, since we all know linux has issues with files that are 'differently cased'.

Diedel · Post by **Diedel** » Wed Dec 07, 2005 5:26 pm

Try 1.5.39 (1.5.40 on the way, btw.

)

fyrephlie · Post by **fyrephlie** » Thu Dec 08, 2005 12:29 am

lol ...

ok

fyrephlie · Post by **fyrephlie** » Thu Dec 08, 2005 12:42 am

your executable on the site did the same thing, so tomorrow when i am awake i will try to compile it. but i don't have much hope.

Diedel · Post by **Diedel** » Thu Dec 08, 2005 4:35 am

Can you post a directory listing of your D2 folder with all subdirectories and their contents please?

I will also prepare a binary creating some informational output to ~/d2x.log to hopefully give some hints about what's going on here.

firefly,

d2x-xl v1.5.41-Linux has some logging to ~/d2x.log built into it. Get the binaries, run the program, and post the contents of that file here please.
