Issues with GemRB 0.8.4

[Caillean]

Well, if I can help with testing something more, just tell me. As for the halting problem - you're losing me here Amazing that you can actually make something out of this stuff the debugger spits out.

Resting should be fine now. I forgot we track the time of the last rest for fatigue purposes, so in the end there was nothing too ugly included.

 

Breagar: I think that creature is actually missing from the new area. You could test that with a fresh build of gemrb, where the crash is gone, but it wouldn't say anything about the cause. I can retry with hopefully clearer gdb instructions, if you're up to it.

Heh, great that it wasn't all too ugly - you're really quick with fixing that stuff! Sure, I'd love to try that new build, and also the debugging, if you don't think it's a waste of your time. I guess it's tedious for you 'cause you need to give me those step-by-step instructions.

 

Edit: Living in the eternal yesterday, I'm on a 32-bit Linux. Do you have the sources for download somewhere, so I can build it myself?

The only annoying thing is that I can't install the mod and investigate myself. I tried installing bgt about a year ago, but it failed and haven't tried since.

 

For debugging, you can use your current setup.

run gemrb in gdb

press r

load the game and do everything short of starting the cutscene

change back to the console and ctrl-c, so the gdb prompt reappears

b GemRB::GameScript::LeaveAreaLUA

c

start the cutscene

once it halts again, you'll see gdb hit the breakpoint at LeaveAreaLUA

n 3

p actor->GetScriptName()

if script name is equal to ACBRESMI

then just p actor->Persistent(); n 20

else c

 

I'll need the log from when ACBRESMI starts to the end.

[Caillean]

I couldn't get BGT to install without errors, too. Neither with wine, nor with Weidu for Linux. So I did the installation to this point on Windows Don't you have an old XP or even 2k around to set up in a VM for such purposes?

 

Oh hell, I hope I got this right:

(gdb) p actor->GetScriptName()
$2 = 0xaf4dcd8 "acbresmi"
(gdb) p actor->Persistent()
$3 = false
(gdb) n 20
569			if (!CurrentAction) {
(gdb) quit

[lynx]

too much hassle.

 

You got it right, but I didn't. I thought n 20 would be equivalent to twenty n, but it only printed once, so please retry the same thing, except instead of "p actor->Persistent(); n 20", press n and then just enter a bunch of times (will repeat the last command - n for next line).

[Caillean]

Here you go:

Thanks. It's too complicated to continue though, so I'll have to drop the inquiry. The mod won't crash anymore and you said removing the effects made it continue just fine, so the missing cosmetics aren't that important. It could be hiding a deeper bug, but it could also be the mod's fault, so I'm not too worried about it.

[Caillean]

Well, should there be a bug, it surely will show itself sooner or later elsewhere. So, uhm... do you think I can get my hands on your sources that include all the fixes and the changes you mentioned or do you give out just pre-compiled builds between releases?

[lynx]

There's automatically a new build after each push (one or more changes), but if you prefer to compile the code yourself, you can always get the code from github. It's all on the project page.

[Caillean]

Aw, great, downloading now. Thanks

[lynx]

ok, fatigued and bored/area comment times are now properly delayed for travel or corner cases, with some extra randomness to be more spread out.

[Caillean]

Great, just grabbing the latest sources. Plus, I noticed something else about the Bhaal powers not being added correctly in BGT, if you're interested. Started a new game to double-check... The problem is, if charname is supposed to get the same innate spell a second time, it won't work. If you're playing a good char, and you have one cure light wounds spell already, after defeating Mulahey in the Nashkel mines you're supposed to get a second cure light wounds spell after the dream. It says 'Gained special ability...' in the console, but you still have just one cure light wounds.

[lynx]

did you rest afterwards?

[Caillean]

Yes, no change. I have one char that's supposed to have 2x Cure Light Wounds and 2x Slow Poison by now, but she has only one of each.
