Etch/Feisty Segmentation fault

[thelusiv]

Alright, thanks again for the testing. Here's yet another package to test.

This time the combination is g++3.3 and g++-4.1. Same link: http://clemsonlinux.org/~thelusiv/VDrift...-2.package

[Nigo]

same :oops:

if we don't have the same libc version, it would be better to compile it on Etch directly. I will see if I have time to try it this week

[rookie1]

segfault in Feisty too.

[thelusiv]

Well I'm not sure what to do at this point. I think the autopackage devs may even be stumped, though I'll keep asking questions. I guess the best solution would be to make a .deb that will work on Feisty and Etch, and direct users of those operating systems to that.

[Nigo]

I just compiled VDrift (it's sooooo easier and faster on Linux :roll: ) and replaced the binary and it now works

also, in the SConstruct file, when using old_openal=1, "-lalut" is missing

[thelusiv]

Yes, everything should work from a compile. -lalut is missing on purpose, that option is meant to do that, because older versions of OpenAL had ALUT built in to libopenal.

[Nigo]

ok. Also, is it just me or there is something wrong with the AI ? the race begin at 40fps and the framerate drops over time, after 30s I got less than 1fps ??!!
everything is fine on Practice Game

[thelusiv]

It's not the AI that's the problem, but the collision detection routines running on many cars does not perform well. This is mentioned in the known issues section of the release notes.

[thelusiv]

Alright some more help from the ever wonderful autopackage devs (thanks Taj!) I learned that the package was not being double-compiled as I thought it was, and for a subtle reason...because the two different compiled binaries were not going into the right place. I have put up yet another package, this time it is also compiled with debug symbols so you can use gdb to obtain a bactrace of the crash. The new link: http://clemsonlinux.org/~thelusiv/VDrift...-2.package

seems like there's some funkiness with libstdc++

[thelusiv]

Alright last package for tonight: http://clemsonlinux.org/~thelusiv/VDrift...-2.package

If you test this please do the following

Code:

gdb vdrift

wait for vdrift to crash, if it does, then in the gdb console type

Code:

backtrace

and paste the output here.

Also, if you could paste the output of the command

Code:

ldd vdrift

Also the Visual Dependency Walker could provide some useful info. Get it here: http://ftp.sunsite.dk/projects/autopacka....2.package

The problem is getting narrower, and it seems like it might be a problem with apbuild. It is including libstdc++.so.5 when it shouldn't. I'll update on the status of this problem...

[rookie1]

The latest package works in Feisty.

[thelusiv]

That's good to hear.

Here's one more package, this time the difference is that I built the static libraries myself using apbuild, so it can do its magic on the entire thing. http://clemsonlinux.org/~thelusiv/VDrift...ld.package

[joevenzon]

With the package in your 6:26 PM post:

as soon as I click on practice game.

[thelusiv]

Alright here's yet another package. This one was built with a patch to apbuild that should prevent it from statically linking X...
