[theAkito]

Description

Building RetroArch on Raspberry Pi 0 W with DietPi results in a fatal error.

[Description of the bug]

Expected behavior

Running ./retroarch-build.sh should successfully build the application.

[What you expected to happen]

Actual behavior

Running ./retroarch-build.sh doesn't finish building and results in the following error:

gfx/drivers_context/vc_egl_ctx.c:25:23: fatal error: VG/openvg.h: No such file or directory
 #include <VG/openvg.h>
                       ^
compilation terminated.

make: *** [obj-unix/release/gfx/drivers_context/vc_egl_ctx.o] Error 1
Failed to build RetroArch

[What is actually happening]

Steps to reproduce the bug

1. Follow this exactly step by step on a Raspberry Pi 0W.
2. You get to the point ./retroarch-build.sh, command it and wait 1 hour.
3. Be disappointed about the error after a long time of compilation.

There is better documentation nowadays, specific to RPi:
https://docs.libretro.com/guides/rpi/

If you are still around, can you check if compilation works using the method currently described?

Can be probably closed.

Hey, sorry, will test this week.

Spent a lot of hours on trying to make the Raspberry Pi work for this compilation. Am working on a fully compatible script, which completely compiles the product from A to Z.
Currently, it takes immense amount of time for the Raspberry Pi Zero W to accomplish these tasks. Even cloning this repository may take hours, not to mention the compilation itself.

When this will be done, I'll provide the full A to Z script for future reference, in case anyone would like to use it.

Here is the script.

Compilation produced the retroarch artifact successfully, so I deem this issue as resolved.

./retroarch --help worked also fine. Couldn't get past beyond that, as I ran all this headlessly.
