@dankcushions said in Running out of MEM and SWAP when compiling lr-mame:

@johnodon yes, i pointed you towards the script earlier. however the script provides an informed guess rather than a cast-iron guarantee. normally it's enough.

lr-mame is in the experimental packages for a reason...

Gotcha. Thanks for all your help.

@mitu Compile ffmpeg in due course because attractmode. I have recompiled / updated it adding the parameter --extra-ldflags = "- latomic" .
And now if I have been able to compile retroarch, I have even installed version 1.9.0.

Everything works great now :)

Thanks again for doing this!

@kactius i think that,s happening cuz the pi3 does not support opengl
i have the old halflife port on my pi3 so i cant test it on that since i have it working fine.

and right now im working with my pi4

Doesn't sound very positive.

Don't listen to naysayers. If your script works, then it's fine.

Hopefully your advice won't make it worse then.

You should be able to use a single emulator entry instead of passing the video res. via CLI or hardcoding it in the .ini file.

Just to confirm I had email confirmation that the change was merged into master, so post-update I tested again anyway and all works fine.

Thanks for sorting this so quickly.

Cheers

It has nothing to do with the modules, there's something related to the kernel files copied by rpi-update which breaks the compilation - see https://github.com/raspberrypi/firmware/issues/1364.

MrEngman created this issue in raspberrypi/firmware open Kernel 5.4 Module7.symvers, Module7l.symvers faulty #1364

personally, if i was doing this i would make a fork in github with my changes, and then edit the retropie build script to point at it, then compile it through retropie - update via source.

eg https://github.com/RetroPie/RetroPie-Setup/blob/master/scriptmodules/emulators/mupen64plus.sh#L32

if i made a change to the master branch of my fork of mupen64plus-core, i would this line to
'dankcushions core'

note that when you edit retropie scripts the script updater will complain when you come to update it.

@mth75 The patches added by the RetroPie install script work only with the branch/version specified in the script. If you'd like to get the latest dev version, you should also remove the .diff being applied.

Thanks for the report, we'll see how it can be fixed.

@dixeflatline
I think you could compile it for armv8a. How much memory does the switch have? You might be able to compile it on the switch.

@littlehui said in emulationstation can not lauche:

lima driver only support opengl es. Is this the problem?

No, actually is the other way around - Emulationstation needs OpenGL ES for your system to work, but it relies on SDL2 to offer that. If your SDL2 library is not compiled with OpenGL ES support, then it won't work. The RetroPie-Setup script takes care of compiling or installing such SDL2 version (for Raspberry PI at least), I'm not sure your system provided SDL2 library has GL ES support and - also important - accelerated GLES support from the Lima driver.

@mitu

Thank you very much for the reply!!

The bad thing is that I do not know how to write code ... and I'm not sure where I should write the commit (eaac037a9e331e8b26a77239d8dd96b76f86515e) and with what syntax ...

Please, if it is not too much trouble, if I could write the line that I should include in the ir-picodrive.sh and in what position, I compile and see if it works !!!

many thanks!!!

Sorry, I thought I did. But that was in another post.

That said, compiling on a threadripper 2990WX with -J80 is almost hilarious. :-)

@mitu That just gives me a segmentation fault. If it's too much trouble then I'll just try asking the person that compiled lr-mess successfully and hope that he can share it. The reason I wanted to try is because the person said he could succesfully run neogeo cd chd games. If latest mame can also do this now, I wonder how much work would it be to backport it for the mame2003-plus guys.

Nevermind i figured it out. The guide dosen't it make it noob clear that after you have built your own version you still have to actually move the binary to the appropriate folder but as i said in the end i figured it out :)

@mitu Oh I'm aware it's just a front end, I've tried doing RetroPie for my brother in law as a Christmas gift (which I got working easily enough).

And I didn't think to try Github's instructions, I guess I just assumed the main page would work. Tired and ready for bed. Thanks, I'll give it a shot later.
