GSDX page fault at 0x00000020
#1
I have a problem with PCSX2 r5773 and GSDX. When I try to open GSDX config window the emulator crashes, and the stdout shows just a very unhelpful message "killed".

If I select GSDX and *don't* try opening the config window, but just start the game, then PCSX2 crashes with the following:

Code:
/var/cache/pacman/pkg/pcsx2-svn7851/pcsx2-svn/src/pcsx2/common/src/Utilities/Linux/LnxHostSys.cpp(64) : assertion failed:

On pcsx2 1.0.0 I get the following:

zzOgl works on r5773, but on 1.0.0 it crashes with a segfault:

I'm on Arch x86_64 with latest repository packages, gnome shell 3.10, kernel 3.12.5-1 and nvidia 331.20. pcsx2-svn is r5773 was compiled with default pgkbuild from AUR.

for gsdx edit the ini file and disable separate shader ext (set it to 0). Maybe it would avoid the crash but I m afraid of a driver bug.

Which setting is that? The ones I have are:

Also, when I removed -DGLSL_API='TRUE' (so now it uses CG toolkit?) I got slightly further, the config window now doesn't crash but freezes 9 out of 10 times (1/10 it actually works) and when running the game it displays this:

Nope, it still segfaults. I've seen posts from other people and it seems that 331.20 works with pcsx2, so I don't think it's a driver bug.

you have exactly the same trace? I m surprised!

It seems that when the kernel got updated the nvidia driver module did not, so when I've rebuilt the kernel module then GSDX started working Smile The funny thing is that everything worked other than pcsx2 (gnome-shell, dolphin-emu, etc.)

The config window still freezes though, maybe it's a widget library/theme issue.

I'll try compiling it now with -DGLSL_API='TRUE' added back (is it at all important, performance and/or quality wise?)

Btw. do you know why can't I build pcsx2 with debugging symbols? I've changed -DCMAKE_BUILD_TYPE='Release' to -DCMAKE_BUILD_TYPE='Debug', even tried adding '-g' to GCC options, but still when I run via GDB it says 'no debugging symbols'... ?

not a driver bug Tongue2
glsl replace zzogl backend (glsl instead of cg). Normally it could be faster but never have time to test it properly.
There is a cmake strip option (try to search on the wiki, sorry only got a phone). Normally stripping is disabled in debug mode.
