Crash - Launch a new game - ZDoom for Linux

Post by **Edward-san** » Thu Jun 09, 2011 8:14 am

Also: you should add "DNO_ASM=1".

Okay, this is what I ran.

nero@svart:~/trunk/release$ cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo DNO_ASM=1 ..

Seemed to be correct, running make now. *fingers crossed*

It should have been '-DNO_ASM=1'.

Thanks. I cleared out the directory and did it like Graf said but game still crashes. I wonder if anyone else uses this in Natty (Ubuntu 11.04) because it worked fine in 10.10..
I can play it in Losedows ..but would be sweet to have it working again in Linux..

It crashes in this line

Code: Select all

	viewingrangerecip = DivScale32(1, finetangent[FINEANGLES/4+(FieldOfView/2)]);

But I have no idea how the denominator in that division can even be 0 unless for some reason finetangent doesn't get initialized.
Question: Do you use an existing .ini from an older launch? If yes, try to delete it and start again.

Release build works fine for me with Kubuntu 11.04 x86_64.

What does it do this asm code in gccinlines.h :

Code: Select all

        : "%cc");

?

I think this is a 32bit issue, as he said he's using x86 build...

Hey nerotriple6, what's your hardware specs?

nerotriple6 · Post by **nerotriple6** » Fri Jun 10, 2011 1:09 pm

Hmmm it works for 64 but not 32-bit? How... unusual..

Pentium 4 @ 2,4 Ghz
1GB RAM
Radeon HD 46050 1GB

I ran Dragon Age so I should run Doom lol.

Can you post the output of:

?

Well I can confirm that this is a 32-bit Linux issue. After compiling on my Thinkpad A31p (only 32-bit machine I have left that's active) ZDoom did crash with a division by zero error on start up.

Post by **Graf Zahl** » Sun Jun 12, 2011 1:18 am

Can you debug this? You seem to be the only person right now with both the ability and knowledge to see what precisely happens here.

nerotriple6 · Post by **nerotriple6** » Sun Jun 12, 2011 1:42 am

If you do I will be very grateful and give you lots of rockets and many Imps to shoot at.

Post by **Blzut3** » Sun Jun 12, 2011 8:58 pm

OK, this is now in Randy's territory. Apparently this function doesn't work anymore:

Code: Select all

static inline SDWORD DivScale32 (SDWORD a, SDWORD b)
{
	SDWORD result, dummy;

	asm volatile
		("xor %%eax,%%eax\n\t"
		 "idivl %3"
		:"=&a,a" (result),
		 "=d,d" (dummy)
		: "d,d" (a),
		  "r,m" (b)
		: "%cc");
	return result;
}

Calling DivScale32(1, 65536) is apparently causing the division by zero. Using the non-asm code in basicinlines works fine and using MAKECONSTDivScale(32) seems to work fine as well.

Can you show what the compiler turned it into?
