Lock SDL2, MESA and DRM update

FranceMSR

Hi, what is the best way to lock the update of the library in the subject?

I installed official Raspberry Pi OS, Mesa driver, drm and SDL2 from source, then I installed EmulationStation (from source) and it works perfectly with full KMS (not fake one).

I would like to verify the other emulators installing RetroPie in order to share the results, I read that EmulationStation doesn't work with full KMS but it is not correct

For Pi OS packages apt mark hold ... is your friend (see section 3. in [1])
For Retropie-Packages it should be sufficient not to update the scriptmodules and not to install them again. (As retropie-setup is a git repo you can create and use also a local git branch to avoid accidentially updates and re-installs).
For tarball-source installs outside of 1 and 2 you are on your own.

@Lolonois Hi, maybe I didn't explain well the problem. RetroPie script always checks for SDL and Mesa, where is the lines of the script responsible for this behaviour? I don't want that RetroPie mess up with my already installed libraries

@FranceMSR if you add own_sdl2=0to /opt/retropie/configs/all/retropie.cfg RetroPie-Setup will not force installation of the RetroPie version of sdl2.

If the file doesn't exist already you can create it with this line.

(To note: On desktop/x11 targets like RetroPie on x86/x86_64 it defaults to own_sdl2=0 without the entry needing to be present)

@FranceMSR I forgot to add, we don't force any Mesa version to be installed. If you have upgraded Mesa it should be fine.

EmulationStation also should work fine with kms.

@BuZz I did what you wrote but for example when I try to install EmulationStation within RetroPie script I see these lines of log:

I don't want libsdl2-dev(custom) or libgl1-mesa-dev libegl1-mesa-dev libgles2-mesa-dev libgl1-mesa-dev to be installed by RetroPie

Additionally EmulationStation didn't build, I receive this error:

Could not successfully build sdl2 - SDL (Simple DirectMedia Layer) v2.x (/home/<user>/RetroPie-Setup/tmp/build/sdl2/libsdl2-dev_2.0.10+5rpi_armhf.deb not found).

@FranceMSR You won't be able to stop it installing the mesa packages without reworking the getDepends code. I've used a newer mesa but I built debian packages.

BuZz

@FranceMSR sorry I meant you need to set own_sdl2=0 I got it the wrong way round.

@BuZz said in Lock SDL2, MESA and DRM update:

@FranceMSR sorry I meant you need to set own_sdl2=0 I got it the wrong way round.

Ok, make sense.

I built Mesa 22.0.4 and DRM from sources, so if I don't want Mesa and DRM to be messed up need I to remove the dependencies from the other scripts modifying all getDepends variables?

Lolonois

@FranceMSR hmm, I'd rather extend this line with clauses to ignore libs (libdrm, -mesa-dev aso. identified in the emulator scriptmodules), thus not entering the following if branch.

Thanks for mentioning the own_sdl2 switch, I didn't know about it until y'day, @buzz.

FranceMSR

@Lolonois I'll try to modify that line, thanks

Install your Mesa and sdl2 library in /usr/local and config LD for use this before the one installed by RetroPie.
In this way you can use original RetroPie script without lose your build library
