cargo build fails with 'rustc --explain E0554' about raylib-rs

[Dacode45]

It's probably this line in raylib-sys/build.rs

raylib-rs/raylib-sys/build.rs

Line 59 in 731b0c4

Platform::RPI => conf.define("PLATFORM", "Raspberry Pi"),

To run the examples, you can go to the samples folder with cd samples, and execute the example you want using cargo run --bin EXAMPLE. For example, if you want to execute the raymarch example, run cargo run --bin raymarch

Great. Now I could compile.
Maybe that should be on the README?

On raspberry pi, raylib can also run using the Broadcom Drivers.
How to make the binaries not depend on X?

I guess I figured it out?

There were these lines missing on raylib-sys/build.rs:252:
} else if target.contains("armv6l-unknown-linux") {
Platform::RPI

... also there should be one for armv8... rPi3

Now I'm rebuilding everything to test.

I didn't figured it out yet how override the default build options... for instance, even o rPi 1, 2 & 3 one might want to use raylib inside X. Is this done via some sort of build flag?

Thanks for your attention.

Hey, haven't tested the library with rpi yet. I would try to follow the official raylib wiki to see how it's done.

[zertyz]

Yes. I have successfully built & run the C/C++ version in standalone mode before for rPis 1, 2 & 3. Its a meter of passing the define flag PLATFORM=RPI at build time. I don't known rust enough yet to see where this should be done.

BTW my mentioned attempt on the messages above didn't work.

[zertyz]

It ended up not working. The samples must also be compiled with this flag. I'll learn rust a little more so I can eventually contribute with a P.R. Thanks for you attention.
