Odroid XU4 SDL Problem Emulationstation

aaronouthier

I'm not sure if I should create a new topic here, or respond to this one, but I'm sure someone will tell me if I'm doing this wrong...

My issue seems to be the same as above Troubles compiling EmulationStation until I compiled and installed sdl2. Then EmulationStation doesn't start with the same message.

I believe I made it one step further, when I discovered the video driver for Exynos wasn't installed, specifically: xserver-xserver-video-armsoc-exynos . Once I installed that, I get a step further, but still an error.

Feb 09 20:04:05 lvl0:   Error creating SDL window!
        eglQueryDevicesEXT is missing (EXT_device_enumeration not supported by the drivers?)
Feb 09 20:04:05 lvl0:   Renderer failed to initialize!
Feb 09 20:04:05 lvl0:   Window failed to initialize!

Platform: Odroid XU4, 16 GB uSD card, Ubuntu 24.04 LTS from odroid.in site (official). Official RetroPie install script.

Possible culprit or catalyst: Early on, setup complained about some missing Python3 packages. I rectified 2 of the 3, however, package Python3-uinput doesn't seem to exist in the usual repos. I'm not sure where to find it.

Although much of work was done via SSH, tasks requiring xorg were performed, such as running emulationstation, were done from an actual keyboard from the terminal.

Additionally, I didn't realize that I was supposed to type the "sudo systemctl stop lightdm" in the instructions, as the text isn't formatted in the same way as other text to be typed.

I tried it last night, but was basically told that the lightdm service didn't exist. I tried "sudo apt install lightdm", and it installed a bunch of related xorg package dependencies. Still get the same message when running emulationstation. I dd stop lightdm first.

I'm sure someone will want some more info before they can help, but I don't know exactly what, so I'll await further instructions.

aaronouthier

So, I started over from scratch. Followed the directions a bit more carefully. Only difference is I started with Ubuntu 24.04 LTS again, rather than 18.04 as listed in the instructions.

While compiling Emulationstation, I noticed the following:

Is this anything about which I should be worried?

The messages are from the GL version detection part, which is going to error out if you're running the installation outside of a desktop environment. I'm not familiar with a XU4, but I don't see the platform declared with the x11 flag in RetroPie, so I don't see why it tries the detection. What system is detected by RetroPie-Setup for your system - it should be displayed on the 1st dialog ?

aaronouthier

@mitu I don't know which dialog of which you speak?
I can tell you that there doesn't seem to be an xorg server running, so no desktop environment to detect. I'm guessing some missing packages? Nothing else is really complaining however.

How can I tell for sure if pieces are missing? If something is missing, how can I know what?

When you start the RetroPie-Setup script, it's the first page that shows up, with the RetroPie version, platform, etc. All that interface (and the ones started through the options present) is done using the dialog utility.

@aaronouthier It doesn't seem that your system/board is detected correctly. It should detect odroid-xu4 as a platform. Perhaps a more recent kernel has removed the hardware info from /proc/cpuinfo. Can you post the output of the following commands:

cat /proc/cpuinfo
cat /proc/device-tree/compatible

@aaronouthier Thanks for the information. The RetroPie detection clearly fails to recognize your device as a odroid-xu, we'll need to amend the detection routine to include the info exposed in /proc/device-tree/compatible also.

You can bypass the detection by running

cd $HOME/RetroPie-Setup
sudo __platform=odroid-xu ./retropie_setup.sh

and perform the re-installation of core packages/depenent packages (including SDL2) and the emulators/core you wish installed. This is a workaround until the detection is fixed in RetroPie-Setup.

aaronouthier

@mitu I will try in the morning. It's now 30 minutes until Midnight. Turning in for the night.

aaronouthier

While attempting to (re)install core packages, I get:
Could not install package(s): Python3-urwid, Python3-uinput, Python3-sdl2. I have run into this before, and was able to install via apt install the listed urwid and sdl2 packages, but have never been able to find the uinput package in the default repos.

mitu

@aaronouthier That's strange, since this is a standard package in both Debian and Ubuntu. What repositories do you have enabled ?

aaronouthier

@mitu Same as was enabled by default when installed fresh, unless something in Retroarch setup modified it. I haven't changed anything in sources.list . I can't check right this second, as it is still compiling Main packages. I suppose I could use another ssh session though.

I'll be back shortly.

There's no rush. When you get to the system, just look up and check what repositories are enabled/used by your system.

@aaronouthier I see - this is 32bit system ? I think the default Ubuntu repos - and the ports system - don't have these packages, although they're available for 64bit (arm64). Isn't the XU4 a 64bit CPU - shouldn't you be using a 64bit system ?

aaronouthier

@mitu No, the xu3 and xu4 are 32 bit CPUs, to the best of my knowledge.

aaronouthier

@mitu Even if, for some reason, the CPU is 64-bit capable, there is no 64-bit OS available for it.

mitu

@aaronouthier That explains the lack of Ubuntu packages in recent versions. Maybe use the armhf packages from the previous LTS (22.04) - https://packages.ubuntu.com/jammy/python3-uinput ?
