Describe your issue
I have a project that uses rdkafka with ssl. When updating to the latest cross from main, I could no longer get it to build.
I have made a demo project that can reproduce the issue: https://github.com/pizaCat/cross-musl-demo
Here is a copy of the README:
Demo project for a compilation failure with the latest cross (7b79041).
Cross must be installed with
cargo install cross --git https://github.com/cross-rs/cross.git --rev 7b79041`The following fails:
cargo clean
cross build --target x86_64-unknown-linux-muslWith the following error:
error: failed to run custom build command for `rdkafka-sys v4.7.0+2.3.0`
Caused by:
process didn't exit successfully: `/target/debug/build/rdkafka-sys-f2824ebbed8581bd/build-script-build` (exit status: 101)
