From e4bd5cd94a1623312d2ec4eef79cc4dbe7ce3377 Mon Sep 17 00:00:00 2001 From: Tiago Lam Date: Fri, 28 Aug 2020 18:23:20 +0100 Subject: [PATCH] Build dist-x86_64-musl with --enable-profiler. MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Trying to build a Rust project with `-Zprofile` for target x86_64-unknown-linux-musl using rustc 1.46.0-nightly (346aec9b0 2020-07-11), installed with rustup, results in the following error. ``` export RUSTFLAGS="-Zprofile -Ccodegen-units=1 -Copt-level=0 -Clink-dead-code -Coverflow-checks=off -Zpanic_abort_tests -Cpanic=abort"export CARGO_INCREMENTAL=0$ cargo build --target=x86_64-unknown-linux-muslCompiling hello_world v0.1.0 (…)error[E0463]: can't find crate for `profiler_builtins` | = note: the compiler may have been built without the profiler runtime error: aborting due to previous error For more information about this error, try `rustc --explain E0463`.error: could not compile `hello_world`. To learn more, run the command again with --verbose. ``` `-Zprofile` is required here to enable grcov profiling. This is similar in nature to issue https://github.com/rust-lang/rust/issues/57257, which has been fixed in asimilar way at https://github.com/rust-lang/rust/pull/60476 . A fix for Android has also landed not long ago: https://github.com/rust-lang/rust/pull/70054 .
