I’m trying to build a package for ARM, and I’m getting a curious error that prevents it from compiling. The complete error is the following:
Compiling winapi-build v0.1.1
Compiling libc v0.1.12
Compiling wiringpi v0.1.2
Compiling libc v0.2.4

Could not compile `libc`.
To learn more, run the command again with --verbose.
I cannot really understand how it does not find std

The std library is a separate component now. Observe rustc installation progress.
install: installing component 'rustc'
install: installing component 'rust-std-x86_64-unknown-linux-gnu'
install: installing component 'rust-docs'
install: installing component 'cargo'
Note the absence of rust-std-arm-unknown-linux-gnueabi. I don’t know how to make multirust install that http://static.rust-lang.org/dist/

Where should I download it? I have put arm-unknown-linux-gnueabihf in ~/.multirust/toolchains/stable/lib/rustlib but it seems it does not find it pi-rust is as per the tutorial here: https://github.com/Ogeon/rust-on-raspberry-pi .

Did you use one of the cross scripts from the guide, to compile your project?

Sure, btw, don’t see the difference between 64 bit tools and 32 bit tools
I updated wiringpi to the latest git version and now it gives this big error:

The 32 bit version uses a 32 bit version of gcc and it’s there for those who has a 32 bit host machine. That’s all. Those scripts should include the cross compiled libstd in your linking path. Are you 100% sure they are in the ~/pi-rust directory?

I have manually done what it’s written in those files so that pi-rust/bin is in PATH and pi-rust/lib is in LD_LIBRARY_PATH. Now I only get the ld issue, but I still get it even if I’m compiling it in --release mode
In any case, it’s a bit troublesome if I have to manually export the paths.

That’s really strange, and I haven’t been able to trigger those errors, myself. Try to only cross compile the WiringPi crate, to begin with. I know that it should work, so that should tell if it’s independent of what you are compiling.

The wiringpi crate builds correctly, I’ve published my changes here: https://github.com/OpenStratos/OpenStratos-rs

Your cross64 script uses $HOME/workspace/pi-rust. I changed it to $HOME/pi-rust and it built without errors.

I had the pi-rust and pi-tools in $HOME/workspace. In any case, I did all the tutorial again, compiling Rust and everything, and put it in $HOME just as the tutorial showed, step by step, and changed the cross64 and cross32 executables for the ones in the repo but I still get the LD issue, even in --release mode
The error is this one:

Then I get a bunch of these:
/usr/bin/ld: /home/razican/workspace/openstratos/openstratos-rs/target/arm-unknown-linux-gnueabihf/release/openstratos.0.o: Relocations in generic ELF (EM: 40)
And finally this:
/home/razican/workspace/openstratos/openstratos-rs/target/arm-unknown-linux-gnueabihf/release/openstratos.0.o: error adding symbols: File in wrong format
collect2: error: ld returned 1 exit status
error: aborting due to previous error
Could not compile `openstratos`.
To learn more, run the command again with --verbose.
So it seems that I have some problem with the linker.

So it seems. The fact that it uses /usr/bin/ld makes me wonder if you are really setting it up correctly, though.

I set up the build in travis just to be sure, and here it is:https://travis-ci.org/OpenStratos/OpenStratos-rs/jobs/104077026
It gives the same error.

That’s a quite different setup, and I don’t think it should be linking with /usr/bin/ld.

I got that setup from the libc compiler script, and in my computer I use the one provided by the tutorial, so it seems it doesn’t have anything to do with the setup.

Are you sure this part of Cargo.toml is in effect?
[target.arm-unknown-linux-gnueabihf]
ar = "arm-linux-gnueabihf-gcc-ar"
linker = "arm-linux-gnueabihf-gcc"
I mean, since it links with cc instead.

You could remove it and see if anything changes. The way I understand it is that it belongs in a .cargo file.

i solve this by installing rust nightly release
but you can download it manually from
