ODROID XU4 - gui environment installed but Failed to open X11 display error

[Calvin]

I am running the setup on my pi and got the same error.

Code: [Select]

sudo apt install libgles-devfixed it for me

Apparently I don't have it:

Code: [Select]

arcade@odroid:~$ sudo apt install libgles-dev

E: Unable to locate package libgles-dev
arcade@odroid:~$

oof. Maybe to

Code: [Select]

sudo apt search libgles to find a suitable package.

BTW. I went through with the compile on a Pi4 but I get some errors when building attract that I can't find a solution for.

I'm currently installing a Mate desktop version... I was reading elsewhere that some of these libraries are included with the odroid full mate desktop - I'm testing that theory.  Right now running all the udpates.  going to try to compile the SFML-Pi here soon.

I have a prebuilt image for the Pi 3b+ but I have not tried to get anything running on the Pi4.  My 3b+ image runs without X11 and uses Attract so I'm pretty sure it can be done.

Ok SFML-Pi built correctly with GLES but Attract is failing with this:

Code: [Select]

collect2: error: ld returned 1 exit status
Makefile:493: recipe for target 'attract' failed
make: *** [attract] Error 1
arcade@odroid:~/attract$

We're close now though!  If I can get attract to build I think it might just work!

I think these are the important bits:

I do have the libgbm-dev installed...

Is yours failing on the same undefined references mine is?

Ok my problem was that I forgot the USE_DRM=1 ... once I did that it compiled but it is giving an error on running:

Code: [Select]

Couldn't find required EGL extension: EGL_MESA_platform_gbm or EGL_KHR_platform_gbm
Aborted
Any ideas?

[Calvin]

Not really, sorry. I think I saw a dependency somewhere for Mesa. Not sure if this was attract tho. You could try installing mesa (maybe libmesa-dev. idk) At this point I am taking shots in the dark. 

EDIT: Did you run

Code: [Select]

sudo make install USE_GLES=1 ?
