Others will profit from better error message, yes. But Isao's problem won't be solved by that. We have fg that just aborts. That is a problem regardless of the availability of a soundcard. One cause for this is that people use wrongly compiled freeglut/SDL libs, where exceptions aren't enabled and thus the stack unwinding informaion is lost. So the boostrap function never gets the exception, but rather calls terminate() and aborts. This is not a FlightGear bug. OTOH, we suffer from it and should maybe add a hint to the error message or a trouble-shooting README. Do you already have a clue where in simgears code this exception is thrown? Nope.

Re: [Flightgear-devel] Re: Help ! on a Run-Time Error !
I've installed my SimGear in /home/knoppix/ , not in /home/knoppix/FlightGear-0.9.9/ For some reason, there is only source directory for SimGear. I don't see any other SimGear related stuff in /home/knoppix/ . Anyway, I went to /home/knoppix/source/simgear/sound , and did ./openal_test1 jet.wav and ./openal_test2 jet.wav With ./openal_test1 jet.wav , I get no error but no sound. But with ./openal_test2 jet.wav, I get the same exception ! terminate called after throwing an instance of 'sg_io_exception' Aborted But I hear the jet.wav just fine with XMMS. That's what gets me confused.

I stared at the stack trace for a while, and I suspect the following code section from ATCVoice.cxx : bool FGATCVoice::LoadVoice(const string voice) { // FIXME CLO: disabled to try to see if this is causign problemcs // return false; ifstream fin; SGPath path = globals-get_fg_root(); path.append( "ATC" ); string file = voice + ".wav";SoundData = new SGSoundSample(); rawSoundData = (char *)SoundData-load_file(path.c_str(), file.c_str());I think the file path for the "/data/ATC/default.wav" SGPath path = globals-get_fg_root(); path.append( "ATC" ); is not resolved correctly. #6 0x083a0ff8 in SGSoundSample::load_file (this=0xb2da290, path=0x0, file=0xb2da10c "default.wav") at sample_openal.cxx:388 #7 0x080c61f2 in FGATCVoice::LoadVoice (this=0xb1e8040, [EMAIL PROTECTED]) at ATCVoice.cxx:58 How you guys think ? I'm gonna set a breakpoint right after "path.append("ATC");" to see what is set in the path string. Boy, I haven't done any coding / debugging in the last several years, so it's gonna take a while.

the exception text, as I explained above.
It's a bit frustrating to exit because the sound is not working, or not
setup correctly. That draws a lot of frustrations, and angry complains
we see on the forums could be attributed to that.
I commited a patch where exceptions are caught nearer of their throw, so
we can use a degraded, silent, but working, code path.
An alert should be displayed, because the try/catch is at the right side
of GLUT.
Isao, update CVS, and tell us if FG is still aborting for you. If yes,
send a new backtrace.
