Segmentation Fault in today's SVN build on Ubuntu

Post by Master Ar2ro » 22 Aug 2006, 16:38

Today's SVN seems to be a bit buggy... the last one I compiled (0.0.20.1) hadn't crashed even once, while this one (0.0.21) had done so 3 times already, however I still have problems reproducing each of those crashes. The last one I had was under gdb, so here's the info:

Code: Select all

Program received signal SIGSEGV, Segmentation fault.

    at graphics.cpp:123
123         return drawImage(image, 0, 0, x, y, image->mBounds.w, image->mBounds.h);

I was doing nothing else but moving this time. The last time it crashed I was trying to set up the FPS limit. I was trying to reproduce that bug when this crash happened. I'll test those things a bit more later today.
Just for the info, I'm running the LATEST SVN (checkedout today, 22 August 2006 at around 15:30 CET), compiled on gcc 4.0.3 and Ubuntu 6.06. I'm running a self-compiled version of guichan as well.

Here's a screenshot (after gdb caught the crash):

//EDIT: Just checked it again. This bug is repeating every time I walk a while under that palm. Doing nothing else right after login, I go under that palm and walk around it a few times in misc directions, and it crashes.

Code: Select all

Seems that `make install` doesn't copy those images to the tmw data folder. I copied them manually, but it seems there's something still missing, the log now has a lot of messages like:

Code: Select all

[16:34:07] Item Manager: Missing slot parameter for item: 501. Cactus drink
and no items have their names or descriptions in the inventory. From the log it seems that all the items are missing.

Crashed again. I was fighting a maggot. This time all the graphics are in place, and the log doesn't say anything about missing images. Just the missing slot parameters as above. The log ends like:

Code: Select all

And here's the gdb output (the same as above)

Updated makefiles to account for new ambient images and changed the version
from 0.0.20.1 to 0.0.21.
May it works now ;)

I have bad news for you Matt. That changelog message was already present when I checked out the SVN, and the ambient images were copied correctly. It's the item images that were missing. My /usr/share/tmw/data/graphics didn't contain items folder at all. Though I still don't know why the missing slot parameter thingy appears in the log.

the slot parameter is unnecessary.

Then what might be the reason for not showing any item names or descriptions in-game? The only item I found that actually had the name and description shown is Santa's hat, the rest doesn't have anything written, just the image.

Thats something i would like to know, too. i thought i caused it when i changed the way item images are loaded, but obviously i haven't. i reloaded the revision before my changes and the bug was already present. someone seems to have caused it in the last weeks without noticing. i already wanted to do a big search for the last revision where it worked but unfortunately i didn't found time to do it immediately and then forgot about it.
