Emulator

What GPU driver are you using on Linux?

Does the issue happen in the GLSL-master branch, too?

On linux I use fglrx-driver 1:12-6+point-1 (Wheezy Version of ATI Proprietary)

I got the branch with
git clone -b GLSL-master https://code.google.com/p/dolphin-emu/ dolphin-emu
is that right ?

You can checkout a new local branch from an existing clone using "git checkout -b GLSL-master origin/GLSL-master".

The build fails

Try temporarily uninstalling glew, Dolphin will use it's own glew copy then which has it defined.

Ok it's done, now it's just crashing (dolphin windows disappeares) without any message on any game start. "Clearing code cache" game window stays black and all dolphin disappeares ^^

Alright that really is bad...
Can you create a backtrace or something?
Try setting CMAKE_BUILD_TYPE variable in the CMakeCache.txt in your build dir to "Debug", then rebuild, then call "gdb " and type "run". It should print a backtrace of the crash then.

Just comment out all lines that error out with SaveData, i.e. put // in front of each line containing SaveData.

Just did it but now

Same there. Just useless debug stuff, anyway.

CC'ing degasus to fix the compile failures in his branch when DEBUG is defined.

As in, just comment that stuff out as well :p

Here's the log !

Uhm, does it output any more useful information when you type "bt" after the segfault happens?

New log

btw, this game, unlike other metroids, loves VBeam speedhack

Maybe the performance differences is because of your old linux driver vs your updated one on windows.

GLSL compilation issues should be fixed.

zype: your backtrace is from our fastmem implementation (it raises segfaults often), can you please disable it first and make a new one: http://markus.members.selfnet.de/dolphin/disable-fastmem.patch
just type in dolphin project folder: "patch -p1 < disable-fastmem.patch"

Ok I'll do it this week-end, haven't got my PC with me.
Yeah I thought about the driver problem, but it's strange cause internal resolution doesn't affect the issue at all, and it happens only with this game. Anyway, I will test it this WE !

I applied the patch and rebuilded dolphin in debug mode but the window is still black and dolphin crashes.

zype: this patch and the debug build wouldn't help for the crash, but they will make the gdb traceback much better. Can you please make such a traceback again with this patch and debug build and upload it? Best would be a full traceback: "bt full"

Wow now I really don't understand anything :/

When I start dolphin (GLSL 740-dirty Debug) through gdb it doesn't crashes (nothing appears in the game window except from AR codes, material, etc.)

When I start it without gdb with the icon on my desktop (and it points to the same executable) dolphin is still crashing Oo'

wtf? So let's try to disable some random parts :-)
The most experimental feature used on your gpu is pinned memory. Try to disable it here:
http://code.google.com/p/dolphin-emu/source/browse/Source/Plugins/Plugin_VideoOGL/Src/Render.cpp?name=GLSL-master#257
by replacing this line
g_Config.backend_info.bSupportsGLPinnedMemory = GLEW_AMD_pinned_memory;
with
g_Config.backend_info.bSupportsGLPinnedMemory = false;

Ok games are starting on GLSL branch if GLEW_AMD_pinned_memory is disabled.
But it's still the same the speed stays at 50% while it's normal on windows.
Btw I upgraded the fglrx driver on experimental http://packages.debian.org/fr/experimental/fglrx-driver
The version is 13.1-2 ;)

No need to disable pinned memory in latest now. It should work just fine.

I retried with lastest master branch, without configuring anything, the low speed is still there. I will try with ubuntu with lastest version of dolphin and fglrx maybe tomorrow or sunday.

I have a similar problem (or the same), dolphin is slower than previous versions in linux and have bad sound. For example "The last story" in 3.5-1093 goes slow but the sound is correct and playable (amd 955 kubuntu), but the same time the 3.5-1496 and newer (from git) are 5 or more fps slower and the sound cuts.
I not know the windows version, but the performance should not decrease.
The two have the same configuration.

JordiComa22: which backend have you tested on windows? Linux doesn't support DirectX, so only OpenGL is supported and compareable. You also haven't told your tested gpu+driver
