This repository demonstrates an issue with cross-rs and/or cross-toolchains.
For reference, to set this repository up:
git clone https://github.com/cross-rs/cross
cd cross
git submodule set-branch --branch powerpc-musl docker/cross-toolchains
git submodule update --init --remote
cd ..Then, once it's up:
cd cross
cargo build-docker-image powerpc-unknown-linux-musl-cross --tag local
cd ..Issue #1, at the end of the above, I get the warning, which may or may not be relevant:
1 warning found (use docker --debug to expand):
- UndefinedVar: Usage of undefined variable '$PKG_CONFIG_PATH' (line 25)
At this point, build the container represented by the Dockerfile in this repository:
docker build . -t cross-issue
Then, try running cross in it:
docker run -v /var/run/docker.sock:/var/run/docker.sock -v $(pwd):/project -w /project --rm cross-issue \
cross +nightly build --target powerpc-unknown-linux-musl
Compiling hello v0.1.0 (/project)
error[E0463]: can't find crate for `std`
|
= note: the `powerpc-unknown-linux-musl` target may not be installed
= help: consider downloading the target with `rustup target add powerpc-unknown-linux-musl`
= help: consider building the standard library from source with `cargo build -Zbuild-std`
For more information about this error, try `rustc --explain E0463`.
error: could not compile `hello` (bin "hello") due to 1 previous error
At this point, given the Cross.toml present, I'd expect these errors not to make sense.
So I try passing -Z build-std:
docker run -v /var/run/docker.sock:/var/run/docker.sock -v $(pwd):/project -w /project --rm cross-issue \
cross +nightly build --target powerpc-unknown-linux-musl -Z build-std
