crossbuild on mac arm host with zigbuild to target aarch64-unknown-linux-musl fail #26

Open gen-xu opened 4 months ago

gen-xu commented 4 months ago

Host: macos arm64 Target: aarch64-unknown-linux-musl

when using zigbuild, cargo zigbuild --target aarch64-unknown-linux-musl for project that dependes on rdkafka, so indirectly uses krb5, the build fails with following error:

that looks like it can't find #include "kcmrpc.h", while this #include is defined __APPLE__ section, which should be off when compiling target is linux-musl

Is this an issue in krb5 build/configure ?

Hey, sorry—afraid we're not able to offer support for cross compiling issues in general, and in particular cargo zigbuild is not something we're familiar with. Happy to take a PR if you're able to debug this issue yourself, though. I'd start sniffing around here:

https://github.com/MaterializeInc/rust-krb5-src/blob/19f84733c09137ec8818046c4627f9874cfe6ec9/build.rs#L36-L37

Perhaps cargo zigbuild doesn't set the TARGET environment variable as cargo build does?

Thanks for reply and the hint, it does set the TARGET correctly though

Metadata { host: "aarch64-apple-darwin", target: "aarch64-unknown-linux-musl", build_dir: "/Users/gen/rust-krb5-src/target/aarch64-unknown-linux-musl/debug/build/krb5-src-66a2027f1b8020ae/out/build", install_dir: "/Users/gen/rust-krb5-src/target/aarch64-unknown-linux-musl/debug/build/krb5-src-66a2027f1b8020ae/out/install" }

I tried comment out following lines in build.rs and it worked afterwards for both cargo build --target aarch64-unknown-linux-musl and cargo zigbuild --target aarch64-unknown-linux-musl

        // If we're cross-compiling, let configure know.
        if metadata.host != metadata.target {
            configure_args.push(format!("--host={}", metadata.target));
        }

Instead of comment out, I also tried just change the configre args push line into

configure_args.push(format!("--host={}", metadata.host));

this also worked for both cargo build --target aarch64-unknown-linux-musl and cargo zigbuild --target aarch64-unknown-linux-musl

before this change neither commmands worked, created a PR for this
