+ (( CROSS_RUSTC_MINOR_VERSION >= 48 ))
/usr/bin/aarch64-linux-musl-gcc.sh: line 11: CROSS_RUSTC_MINOR_VERSION: unbound variable
The underlying problem seems to be that cross uses by default main tag that may be incompatible with the current version. Using the tag that matches the version (0.2.4 in this case) seems to work around the problem.
What target(s) are you cross-compiling for?
aarch64-unknown-linux-musl
Which operating system is the host (e.g computer cross is on) running?
- macOS
- Windows
- Linux / BSD
- other OS (specify in description)
What architecture is the host?
- x86_64 / AMD64
- arm32
- arm64 (including Mac M1)
What container engine is cross using?
- docker
- podman
- other container engine (specify in description)
cross version
cross 0.2.4 (4645d93 2022-07-10)
Example
git clone https://github.com/taiki-e/cargo-llvm-cov
cd cargo-llvm-cov
cross build --target aarch64-unknown-linux-musl
Probably this can also be reproduced with a crate created with cargo new --bin instead of cargo-llvm-cov.
