[SOLVED] Segfault after creating ground shading

[sevcsik]

Hi!

I'm trying to run spring 0.80.5.2 on my arch linux netbook (intel gma945GM, 1024x600), and it segfaults after creating ground shading. I tried to set Shadows=-1 in springrc, but it didn't help.

My spring install is built from source via AUR. thanks for the help.

what is AUR?
please compile again with debug symbols, and run in gdb, and then execute bt if the crash occurs, and post the stack trace.

[sevcsik]

AUR is the build system of arch linux, like portage for gentoo. ok, i'll try to compile with debug symbols.

[hoijui]

with cmake, you had to use -DCMAKE_BUILD_TYPE=DEBUG2

[sevcsik]

thanks, i was just trying to append -g to cflags :)

disabling ground decals might fix your problem (GroundDecals=0 in ~/.springrc).
jk may have to comment on this, but to me it looks like the graphic card (driver) advertises something it does not really support. which is somethign the intel is known for on linux (according to jk).

[sevcsik]

I tried, but it still segfaults with the same backtrace. btw, i didn't have a GroundDecals line in my .springrc, so i added it.

[hoijui]

UsePBO=0

[sevcsik]

thanks, now the game starts, but it's slow as hell (about 1-2 FPS) and some objects don't have textures.

and i can't go fullscreen (FullScreen=1 in .springrc)

[hoijui]

of course its slow!!
intel gma945GM with linux drivers!

it runs quite some better under windows on this card (15-20 FPS at the start) but if you built some units (100 or so may already be enough), it will get much worse and be unplayable already. there is pretty much no game that will be fun to play and run fine on this card.

about the textures:

[sevcsik]

yes, on windows, it's just about playable :) thanks for the help!

[hoijui]

as i have never really tried myself...
how big of a load can you take? eg.. can you watch/play an online game fine?

[sevcsik]

i haven't played online yet on windows, but if i zoom out about 4-5 steps, the fps drops to ~5. so i don't think it's capable for online games :)

[hoijui]

mm yeah :D sounds so.
thanks for the reply!
