raspberry pi compile error
On RaspberryPi 2 B (32 bits)
I downloaded:
clang libegl-dev libudev-dev libsdl2-dev mesa-common-dev
do I need any other library?
I got the following message:
/OpenLara/src/platform/rpi $ ./build.sh

Second on this same error. My build environment is a Raspberry Pi 4B (4GB RAM) running the latest Raspberry Pi OS 64-bit beta.
I can build the nix platform build without issue, but I would like to be able to build the rpi build as well.
Got the same error message as well with a raspberry pi 3b+
32-bit or 64-bit Raspberry Pi OS?
@ All: Don't use the RPi platform. The old rpi platform uses the DISPMANX API, which is a closed, propietary API from BROADCOM which is now gone for good, in favor of KMS/DRM+MESA.
So that's why it doesn't work on any modern GNU/Linux distro on the Pi. DISPMANX is dead and unsupported for good, in favor or standard APIs.
An specific Pi platform makes no sense nowadays. Instead, use the SDL2 platform: it builds and works on the Pi with no problems at all.
After all, the Pi is simply a *NIX platform running SDL2, and that's what it should be treated like.
EDIT: just build the sdl2 platform as of today's GIT code and works great on the Pi3 and 4, using standard APIs under the hood.
Then if that's the case, then the RPi platform should probably be marked as deprecated and removed from the codebase.

I have already suggested that to master @XProger At this point, the Rpi platform is only causing confusion because no modern Pi OS will work with that.

I installed libedil-dev libudev libsdl2-dev mesa-common-dev, switched to sdl2 folder and executed build.sh, but still failed to compile. Platform: RPi4
