Xash3D Engine on Raspberry Pi

[GAMELASTER]

I mean normal console in Raspberry Pi (no SSH, of course)
Oh, i dont mean FBA but FBO (crap)
https://github.com/ptitSeb/glshim#libgl_fb
Look this. But it is setted correctly (1), so I dont know why it dont work for me.

For you it is work good? You used a X server or no?

[CockPitt]

Yes I'm using an X server. Are you using wheezy or jessie? I have had similar problems with wheezy. Also what command are you using to launch the game?

[GAMELASTER]

Im using RetroPie Jessie Image. It's not contains a X server, all games running as fullscreen FBO. Maybe for this I don't saw anything, but... Parameter is setted to draw in fullscreen mode at glshin

[ptitSeb]

HI there, I don't a RPI , so cannot be of much help, but about the lack of X server, I think it will be an issue.
glshim use X for a few function (but you can try to activate the Android build, as this one doesn't use X). I'm not sure if Xash3D itself use X (for input mainly), maybe just SDL2.

[GAMELASTER]

I know the PPSSPP running under SDL and it have this solved. I run the game at i see only console, no game :/

[GAMELASTER]

LIBGL_FB=1 LIBGL_BATCH=1 LD_LIBRARY_PATH=/opt/vc/lib:/home/pi/hl/SDL2_image-2.0.0/build/.libs:/home/pi/hl/SDL2-2.0.3/build/build/.libs:/home/pi/hl/glshim/lib/:. ./xash3d -console -debug

My launching options

[GAMELASTER]

Im sorry for spamming with posts, actually I know why its not working, in SDL2 is deleted a FrameBuffer support, only DirectFB, so I recompiled SDL2 with DirectFB, but still its not working good. Any ideas to make FrameBuffer Output working?

[GAMELASTER]

Maybe I know how to run it, I will try that today, its needed to only run XVFB (X Virtual Framebuffer) before game and then it will be maybe works!

[CockPitt]

@GAMELASTER I'm curious if it worked?

Today I successfully launched Half-Life with the new OpenGL driver on my old screen (1920x1080). I skipped the glshim part and launched by typing:

Code: Select all

LIBGL_FB=1 LIBGL_BATCH=1 LD_LIBRARY_PATH=/opt/vc/lib:. ./xash3d -console -debug -nosound

I disabled sound because it caused even more issues than I had with this driver. Even though the fps are low (15-18 I guess, please note that the driver is still in progress) the framerate doesn't drop in intensive areas as far as I noticed, but I was only able to play half of the intro. I also noticed a decent performance boost on lower resolutions. But the game doesn't scale right and it crashes more often. Most crashes are kind of odd because it throws me back into the main menu but I'm not able to resume the game. It's now possilbe to alt+tab. The console in game still doesn't work but the terminal seems to be very chatty now. I also wanted to mention that the CPU load is at around 10-12% (25% with glshim). I think the driver relieves the CPU and puts the load on the GPU instead.
About the "crashes": I'm not able to play through the full intro every time it throws me back into the main menu at this part of the game: http://imgur.com/F8kbvul

Console says:

I think the performance could be improved with ccmake but I still wasn't able to use ccmake with hl.so and XashXT

But it seems like "ccmake Makefile.rpi" doesn't work. I'm pretty sure it worked before. Now it says the source is a file not a directory. http://imgur.com/8OyxHvI

[ptitSeb]

@CockPitt: ccmake cannot be used on XashXT or hl.so because those are simple Makefile project, not CMakeList based ones. but just edit the Makefile.rpi to tune the CFLAGS like with ccmake.

The crashs you have are probably inside the driver (you can still try to get a backtrace with gdb), so not much I can do.

[CockPitt]

@ptitSeb
I formatted my sd-card again and rebuilt everything. Now I can clearly say it's not because of the driver, Half-Life keeps throwing me back into the main menu. The driver has never been enabled on this OS. The only thing I could imagine causing it is this command: "sudo ldconfig". I added it because often after compiling everything Half-Life wasn't able to start.
I'll post a backtrace of the error later.

[CockPitt]

When I tried to reproduce the error I experienced no throw backs at all. I played a bit around and noticed that it's the "-console" launch instruction is responsible for the issue. It has never been a problem before so I don't know why this happens. I'm not sure if a backtrace for this error even works because the game doesn't crash, I can load a save game or play new game etc.

[super213]

Any updates on this working succesfuly. maybe you should look at the android version it runs at 60 fps on my note 5 and never goes below 60 (my phones framerate is hardlocked at 60fps). take a look there.

[iNC0GNi70]

Yo dudes
I was wondering if anyone actually succeeded into making it run in a stable manner on a Raspberry.

[CockPitt]

@super123
I remember it running pretty well on the Raspberry Pi, for it's graphical capabilities. I finished the campaign multiple times and most scenes ran at quite decent framerates (I can't provide fps numbers because the Frame counter doesn't work). Only the audio output was poor and full of stutters.

The bossfight is not very funny because of the low fps which vary between 5 and 10 I guess but pretty much every other scene is absolutely playable on my Pi.

However, I would really like to play around with Half-Life again, testing the performance with the advanced open GL-driver, but my installation guide doesn't seem work anymore, so I can't get it to launch.

@iNC0GNi70

I played through Half-Life a few times now. It runs pretty stable (about 1 or 2 crashes a run). The bossfight is not very funny because of the low fps which vary between 5 and 10 I guess but pretty much every other scene is absolutely playable on my Pi.

[CockPitt]

Whenever I try to follow my guide, I get the same output at launch:

That's what the console says, but no window shows up. Any ideas?

I think you didn't built xash3d with the correct flags, as it look for i386 libs.

[CockPitt]

These are the instructions I'm following to build xash3d:

Mmm, ok, try to add "-std=c99" the the -DCMAKE_C_FLAGS="...". I'll fix my github sources later.

[ptitSeb]

Anyway, I have (I guess) fixed my github sources, you can "git pull" and "make -j4" again @CockPitt

[CockPitt]

Building xash3d works now, but the console output at launch of the game hasn't changed.

I'll attach some pictures of ccmake, so you can check if the flags are set correctly:

[ptitSeb]

It's still looking for the wrong libs?
I have to double-check the code...

[ptitSeb]

@CockPitt : I think that hl_386.so reference comes from in your data files. You should try 'grep "hl_386.so" valve/* -rn' to locate the file. That text file is created bu xash3d, and you probably tried it on an x86 version? Try to remove that text file, xash3d will recreate a new one.

[CockPitt]

Code: Select all

pi@raspberrypi:~/Half-Life $ grep "hl_i386.so" valve/* -rn

valve/gameinfo.txt:13:gamedll_linux		"dlls/hl_i386.so"
valve/liblist.gam:9:gamedll_linux "dlls/hl_i386.so"

As far as I understand "liblist.gam" creates "gameinfo.txt".
Removing "gameinfo.txt" didn't change much. At launch the file is being recreated. But it still contains "dlls/hl_i386.so" so the output is still the same.
I had a look at "liblist.gam". It looks like this:

Code: Select all

// Valve Game Info file
//  These are key/value pairs.  Certain mods will use different settings.
//
game "Half-Life"
startmap "c0a0"
trainmap "t0a0"
mpentity "info_player_deathmatch"
gamedll "dlls\hl.dll"
gamedll_linux "dlls\hl_i386.so"
secure "1"
type "singleplayer_only"

I changed "dlls\hl_i386.so" to "hl.so" and the output looks different:

Code: Select all

pi@raspberrypi:~/Half-Life $ LIBGL_FB=1 LIBGL_BATCH=1 LD_LIBRARY_PATH=/opt/vc/lib:/home/pi/glshim/lib:. ./xash3d -console -debug

Did this fix anything? The game still doesn't launch.
