My guess is the opengl extension string is too long.

Quoting: sr_ls_boyMy guess is the opengl extension string is too long.

How can I fix it?

By prepending an environment variable prior to starting the game.

That all depends on which driver you use. The driver will limit the strings for you.
Check the tips for games using Quake 3 Arena engine at the wine DB. I off hand don't
know what variable you need.

Yeah, I had the same problem with SiN Gold.

Here is my forum post discussing how I resolved it:

I am using a AMD card and the open-source drivers.

Soldier of Fortune uses Quake II engine, nots Quake III.

Also there is no problem with other games that use OpenGL and Direct3D. Games like Quake III, Delta Force: Land Warrior, Call of Duty 2 and Urban Terror are running without any problems.

Only in Soldier of Fortune was such a distress.

Yeah, this is a problem pretty specific to Quake II engine games like Soldier of Fortune and SiN.

Since you are using Mesa just enter the following command into a terminal before launching the game from the same terminal window (or shell script like I did for SiN Gold):
export MESA_EXTENSION_MAX_YEAR=2000

And you should be good to go.

There is a Linux port of Soldier of Fortune. Why don't you use it?

Quoting: ageresThere is a Linux port of Soldier of Fortune. Why don't you use it?

You try finding a boxed Loki Software copy of it though, to be fair. It is not exactly up on Steam or GOG.com for sale at the moment.

Your current issue megalanya seems to relate to the game wanting to use a 16 bit colour mode. Some quick research indicates that setting Wine to emulate a virtual desktop through winecfg may help. You should also probably set the game to use Windows 98 compatibility wile you are there to.

I will also point out that for the Windows version of Solider of Fortune you can apparently download a patched DLL that will permanently resolve the extension problem for you:

Because Loki Entertainment defunct in 2001. GNU/Linux version of this game is not available.

I have tried the suggestions you mentioned and many other suggestions already. But it didn't work, unfortunately. Discussion is here:

[http://www.sof1.org/viewtopic.php?t=4311](http://www.sof1.org/viewtopic.php?t=4311)

New "ref_gl.dll" have already been made in "Soldier of Fortune Community Edition". It does not work.

I see you use an AMD card and an open source driver like myself.

"Soldier of Fortune: Community Edition" is available here:

[http://www.sof1.org/sofdownload.php](http://www.sof1.org/sofdownload.php)

If want to try, you can download it here.

FWIW, it is possible to get the native linux port running somewhat:

* Install the Windows version of the game with Wine.
* Grab the[ modified installer for the Loki port](https://liflg.org/?catid=7) (under beta) and extract it with unzip.
* Extract the resulting tar file for the linux port binaries.
* Grab game data files from Wine install.
* Symlink /usr/lib/i386-linux-gnu/libGL.so.1 (or wherever it lives on your system) to libGL.so in game dir.
* Start with ./sof +set gl_driver libGL.so

The game runs and is playable, the big gotcha is that sound doesn't work. Launching it with pasuspender results in a segfault here:
#0 0xf6d3f4f2 in sl_add () from /lib/i386-linux-gnu/libbsd.so.0
No symbol table info available.
#1 0xee110386 in _S_StartSound () from ./liboasnd.so

Gave it a try with Wine 3.1, using the platinum version of the game.

Seems to be working fine with MESA_EXTENSION_MAX_YEAR=2000 and gl_gentextures_broken "1" in config.cfg.

The game used to run natively by using OSSPD just fine on Linux Mint 18.3 (Ubuntu 16.04 based). However, starting with Ubuntu 17.10, OpenAL compatibility seems to be messed up. As the game uses a custom libopenal-0.0.so and liboasnd.so libraries, the game crashes if executed with an OSS emulator that was not a case with Ubuntu releases prior to 17.10. As I tried renaming libopenal-0.0.so and linking system's own OpenAL library to game's directory as libopenal-0.0.so; it returns no sound. I will contact with Alan Swanson who seems to be the owner of Loki Compatibility Libraries.

Sorry to resurrect, but this seems like the latest thread.. Found this while working on getting SoF running on my new system..

I wrote a [resolution](http://dusted.dk/pages/sof-resolution/) hack, and that still works. I updated the page with additional information on how to fix a segmentation fault that occurs because of a too long extension list (what whizse suggest seems reasonable, but didn't work for me on Linux, so I found another way as detailed on the resolution hack page).

I'm having the same trouble as you, getting it to work with padsp.. Someone gives sl_add a bad parameter, probably _S_StartSound.. Now, I've not found the source for libaosnd.so (which provides _S_StartSound) but I've managed to get the modified alsa version from the Loki CD to build and that actually kinda works.. It will play ONE sound, after playback, it crashes, as described by rea987.

I wonder if the problem is that the poor _S_StartSound function ALSO gets unexpected data, in that case, it would get it from the alsa lib, which it loads. If that is the case, we may be able to modify the alsa lib to provide the expected parameters to _S_StartSound..

Anyone got updated info on this ? I'm very interested in knowing if rea987 were able to get hold of Alan and maybe obtain the source for the liboasnd ? :)

I decided to try SoF in Wine while it's on sale at GOG, and it looks like the error in the OP may be due to an issue with Mesa. On my main system (see profile) I get the same error and nothing I've tried has been able to resolve it. However on my old system which uses an Nvidia GPU this error does not occur - no tweaks are required to get the game to start (old system is still running Mint 18 though so that might also be a factor)

Running the game with "+set logfile 2 +set gl_log", the ref_gl section of the log looks like this on my main system:

Sorry to resurrect x2, just for the record I've tried launching with the actual OSS4 drivers (not ALSA's kernel/userspace emulation) which turned out to be not that hard (and didn't at all require nuking half the system) and ended up with the same result - one sound played, then the crash (((
The bug is likely purely user-space, possibly akin to the exported symbol problem.
But cool to have sound working via the OSS in 2020 =P

PS don't think ALSA has anything to do with the game at all, it has to be OSS only.
PPS liboasnd must be a proprietary lib, specific to SoF.,,

Think this deserves a 3rd resurrect...
It's 3 in the morning, I'm wearing my glasses and I've finally got it.

An older libbsd did the trick (http://launchpadlibrarian.net/170117961/libbsd0_0.6.0-2ubuntu1_i386.deb)
LD_PRELOAD=./libbsd.so.0 ./sof (plus your favorite OSS emulator)

Damn it's so simple.
