Build fails due to missing header files

[SvenMichaelKlose]

Latest Raspi OS Lite 32-bit on RPI-3A:

gcc -Wall -Wextra -pedantic -I. -I./raylib -I/opt/vc/include/ -march=armv8-a -mfloat-abi=hard -mfpu=neon-fp-armv8 -O3 -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -lstdc++ -c -o platforms/amiga/rtg/rtg-output-raylib.o platforms/amiga/rtg/rtg-output-raylib.c

There is a comment in the README.md file which addresses this issue. I would also make sure (if you are using the RPi imager) to select Raspberry Pi OS (Legacy, 32 bit) Lite as the ISO to use.

Important note: If you are using Raspberry Pi OS "Bullseye", the main graphics backend for the OS has changed from dispmanx to DRM, and you need to follow these steps instead of just running make:

• First run sudo apt-get install libdrm-dev libegl1-mesa-dev libgles2-mesa-dev libgbm-dev to install the DRM OpenGL/ES libraries, which are for some reason not included with the distro by default. These are necessary to link the graphics output library (raylib).
• Then finally, run make PLATFORM=PI3_BULLSEYE for the emulator to compile successfully.

Thanks! I used that image. It's a friend's dream to have that thing installed, so I'll have to check it out later.

The latest Raspberry PI OS image - as of writing this - is 12 (bookworm). It won't have the /usr/include/interface/vmcs_host/vc_tvservice.h header and none of the packages mentioned in the README will add it. Hence any user will run into this same issue. I had to reinstall the OS image using the legacy bullseye version to successfully compile the emulator.

For anyone using Raspberry Pi OS 12 (bookworm), the failure finding header file vc_tvservice.h can be resolved by adding libraspberrypi-dev to the apt-get command line used for Raspberry Pi OS 11 (bullseye). So the apt-get command line would become sudo apt-get install libdrm-dev libegl1-mesa-dev libgles2-mesa-dev libgbm-dev libraspberrypi-dev. Then run the make command as already indicated for "bullseye".

Doing this I was able to get the build working with "bookworm" and running the emulator binary seems to work properly. If needed I could submit a PR to update the readme.

This build error is still present when using the latest 32-bit Raspberry Pi OS image. The change proposed in the previous comment works for me.

Could someone please send a PR to update README.md accordingly? Or better, update the Makefile to work with Bookworm by default.

Just testing those instructions now and I'll raise a PR after i confirm that it's working.
