Summary: Partial fix for https://github.com/uutils/coreutils/issues/6591 The current code declare libstdbuf as a build-dependency of stdbuf as a workaround to enforce that libstdbuf is compiled before stdbuf. This breaks cross-compilation, because build-dependencies were compiled for the host architecture, and not for the target architecture. The reason this workaround is necessary is that bindeps is available only in nightly at the moment: https://rust-lang.github.io/rfcs/3028-cargo-binary-dependencies.html This commit replaces the "build-dependency" workaround with another workaround: calling cargo manually to build libstdbuf in the build.rs of stdbuf, in order to ensure that libstdbuf is built before stdbuf. Changes: - Removed cpp/cpp_build dependencies: The cpp, cpp_build, and related dependencies were removed because they made cross-compilation in a build.rs file very complex, since you need to pass proper CXX env variables for cross-compilation, whereas cross-compiling rust code using cargo is quite simple. Provided Rust implementations for getting stdin, stdout, and stderr pointers. Switched from C++/cpp macro-based initialization to using the Rust ctor crate for library initialization. - Remove "feat_require_crate_cpp" which is not needed any more, since stdbuf was the only utility using the cpp crate. Tests: This commit fixes e.g. this test: cross test --target aarch64-unknown-linux-gnu --features stdbuf test_stdbuf::test_libstdbuf_preload -- --nocapture - The "i686" build of stdbuf was also broken (stdbuf 32 bits, but libstdbuf 64 bits) and test_stdbuf::test_libstdbuf_preload of the i686 builds in github CI serves as regression test for this issue, no need to add a cross-rs test for aarch64. - The x86_64 musl build of stdbuf was also broken and was passing tests in CI only because it was compiled with the wrong libc (glibc instead of musl) Signed-off-by: Etienne Cordonnier <ecordonnier@snap.com> |
