Crash - Launch a new game - ZDoom for Linux

[Edward-san]

add it as a parameter with the other parameters.

Code: Select all

cmake -DCMAKE_BUILD_TYPE=Release -DNO_ASM ..

[Blzut3]

One other thing to try would be instead of setting CMAKE_BUILD_TYPE to Debug, use RelWithDebInfo.

[nerotriple6]

add it as a parameter with the other parameters.

Code: Select all

cmake -DCMAKE_BUILD_TYPE=Release -DNO_ASM ..

This correct?

Code: Select all

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

Running make in the Release dir. I don't want to mess with my working ZDoom in the debug..

One other thing to try would be instead of setting CMAKE_BUILD_TYPE to Debug, use RelWithDebInfo.

Huh? Sorry.. I'm not so savvy.

[nerotriple6]

.......AND BIG SURPRISE!

It works. I don't think this is a bug. I just think something went wrong (or me messing up) in the compiling process. Perhaps some of the files are write protected and I didn't delete everything between my previous efforts to re-compile it? I just deleted the Trunk folder with Nautilus and I didn't check if everything was gone. Well you guys want to try working on this bug? I don't think it is a bug..

If -DNO_ASM=1 does the trick, this means there's something wrong in the ASM code.

Try to do as Blzut3 suggests:

Huh? Sorry.. I'm not so savvy.

Let me explain you: make a new directory in the trunk, call it as you like. Enter in the directory and do this:

Code: Select all

cmake -DCMAKE_BUILD_TYPE=RelWIthDebInfo ..

create the executable and try to reproduce the crash.

[nerotriple6]

Alright I reproduced the crash. I made a folder in Trunk called testdoom, then did what you instructed, tried to start a new game and it crashed. For the record: the only of my Wads that I copied to the new folder is the Doom2.wad. This crash have been reproduced with the following Wads:
doom.wad
DOOM2.wad
plutonia.wad or tnt.wad (I don't remember which)..

Code: Select all

Yes, finally! That's the report IMHO the devs want!

Before leaving the job to the devs, can I ask you two things? Maybe I'm exaggerating.

1)What happens if you run zdoom (in the new directory) using an new ini? I mean, run zdoom like this:
./zdoom -config newini.ini

It creates a file called "newini.ini" in your directory. Can you make it crash again? If yes, please post the new crash log.

2)This is very long and may take a lot of time, I'd like to help you if I could reproduce the crash... I'll write it in spoiler for your sake. If you don't have the time, I'm not obliging you to do so.

---

I don't know how this can be an help, but can you check if you have the same crash changing the svn revision to some old one? (the command to use in trunk directory is: svn update -r numberofrevision )

Be careful! This method can be unstable since it may happen that no revision is the culprit, then you can only hope in the devs' wise suggestion.

If you want to proceed, use this rule:
Choose an old revision, like for example r3171, compile it and check out if you can make it crash with this build.
a)If yes, then change revision number to an older one and redo the check;
b)if not, then it means that between r3171 and the latest one there exists a revision such that the change broke your game.

If you're in case b), then do this:
consider the "medium value" between the two revisions number, compile it and check out if this crashes for you. If your build crashes, then it means you should check between r3171 and the "medium value", else you check between the "medium value" and the latest. Do this until you find the culprit revision.

If you're in case a), if you check for example r3100 and you don't have a crash, then it means that the culprit revision is between r3100 and r3170. In this case you proceed as a). Else, redo b) checking out an old revision.

I'm foolish right now...

Yes, finally! That's the report IMHO the devs want!

I leave this to the devs, but I don't know how it helps the "<value optimized out>" -iness.

For now, if you want to play, use the debug build, since that works fine on you.

Thanks to you, both the release and the debug builds are working. I will leave them as such.

Thanks. Doom is such a great game..

[Edward-san]

I've changed the post above you by adding some new procedures to search out the bug. If there's someone with the same problem as yours that could help me doing as I suggest above...

[Edward-san]

Scrap the second task, nerotriple6. Can you do me a favor and check out if you can make it crash if you use svn revision 2508 (version 2.5.0 of zdoom) ?

[edit] I hope it isn't too late and so I hope he comes back asap...

[nerotriple6]

Sorry Edward. I've been really busy ..and I had to install Windows... thus I had to reinstall Ubuntu..

I am enroute to reinstall Zdoom after the format, before I do that, would you mind explaining to me what you wanted me to do? From scratch.

[Edward-san]

The idea is to find the revision which made you begin crashing. Let's start with revision 2508, the 2.5.0 revision. Can you reproduce the crash with that revision? (Using the same instructions as here)

[nerotriple6]

Cool. Okay, just to make sure...

I run these commands in terminal?

Code: Select all

sudo apt-get install build-essential zlib1g-dev libsdl1.2-dev libjpeg62-dev nasm tar bzip2 libgtk2.0-dev cmake
sudo apt-get install subversiony
svn checkout http://mancubus.net/svn/hosted/zdoom/zdoom/trunk

Then I get

Code: Select all

Checked out revision 3219

So I download the Fmod packs
Then enter trunk directory and create one called release, then enter that before I..

Code: Select all

cmake -DCMAKE_BUILD_TYPE=RelWIthDebInfo ..

All this correct? Currently downloading the Fmod packs..

EDIT: to make sure I made a test dir.. now I just move some Wad in there and try.. ...forgot to run make.. am now..

[nerotriple6]

Result of everything above

Code: Select all

+MAP01 - entryway
