was the working version 0.61 as well ?
do you have a joystick attached ?

Sorry to bump an old topic but I have the same problem and I just downloaded DosBox a few minutes ago 🙁.

I have the same problem. I can run System Shock with just DOSBox by itself after mounting the drives, but I can't use D-Fend to play the game after setting up a profile. I tried to change the cycles and such because it runs slow when I use just DOSBox.

go to the d-fend forum then.

Just downloaded the 0.61 src rpm, compiled. No issues in the compile other than a few warnings. Dependency compilation noted that libGL was required. The rpm built, so it must have found the dependency.

Go to install, complains about libGL. Override with nodeps.

Go to run, and
~/Files/rpm> dosbox

Help?

(Runs fine on my 64 bit install of Gentoo though!)

Decided to test the CVS version of the code. Same problem exists.

uhm longshot
./configure --disable-opengl

🙁 Nope. Did that with the CVS copy (and should have said so). I'm tempted to blow this machine away anyway, as it's getting a bit crufty (and I want to load Gentoo on it).

CXXFLAGS="-O0 -ggdb3" ./configure --disable-opengl && make clean && make
cd src
gdb dosbox
run

interresting it looks like the sound system of sdl crashes.

try this:
export DOSBOX_MIXER_NOSOUND=TRUE
./dosbox

and it runs. So *hrum*. The Gentoo box is running SDL 1.2.7, while the Fedora box is 2 - 4 revisions behind depending on what part of SDL is being discussed. Though, with RedHat, you can never tell due to the level of backport patching they do.

the crash seems to be in arts. Maybe you can specify a different output method for sdl (sdl responds to defines as well)

Silly question time:

What environment variable controls SDL? Tried SDL_AUDIODRIVER=alsa, and that didn't seem to do anything useful other than make dosbox think there was no driver at all!

http://frida.fri.utc.sk/~sam/devel/links-sdl/sdl-env-vars

the one you used seemed to be correct. Be sure to unset that DOSBOX_MIXER variable then as that one disables dosbox sound output. I suggested that as the crash was in sdl it's audio appartment.

Yeah, I did unset it 😀 Need to poke a bit harder I think, probably when I'm not at work. Thanks for now Qbix.

Well, I ended up wiping the laptop, and installing Gentoo 😀 I've got matching library versions for libsdl and sdl-net on both machines. The 32 bit box ran dosbox once, and every time since then has been a segmentation fault that caused SDL to go splat.

I think, however, that I may have found a partial solution (machine is compiling other stuff atm, and a bit lagged) -
$> artsshell terminate
$> SDL_AUDIODRIVER='alsa' SDL_DSP_NOSELECT='true' dosbox

Laptop has an onboard i810 audio chipset, and it may well have issues with using select() against it. Sound stutters a slight bit once in a while, and I can tell that this P4 1.7 doesn't have the grunt of my Amd64-3000 😀, but it works. Worth adding to the caveats or something in the distro perhaps?

I'll try later without terminating arts, and seeing if the noselect method works, but the docs don't mention it working with arts.

hmm so switching to alsa solved to problem.

Terminating arts is only needed when you soundcard can't play more that one stream at the time. (I think)

Buggy stuff then. Feel free to "bug" the sdl people about it. Dosbox is doing little wrong here.

I'm sorry. Maybe I'm just extra dense but I just downloaded this for the first time and most of what was said in this forum went so far over my head I didn't even feel the breeze. I'm getting this error and would like to fix it. Like I said... sorry for being dense but could someone help me out? I'm running a Athalon XP 1.7G.
