While building the rust toolchain, the build system ends up using cargo (from [...]/output/build/host-rust-bin-1.74.1/cargo/bin/cargo) to build some tools like rustdoc-tool. But the host-rust package doesn't use the cargo infractructure (since it provides cargo binary) and our cargo environment variables [1] are not set to crosscompile cargo packages in the rust toolchain. For exemple, we usually set RUSTFLAGS="-C link-arg=-Wl,-rpath,$(HOST_DIR)/lib" to force cargo using libraries provided by Buildroot in $(HOST_DIR)/lib. RUSTFLAGS is actually needed to find zlib library (host-zlib) to link rustdoc-tool when zlib is not installed on the host. Add $(HOST_PKG_CARGO_ENV) in HOST_RUST_BUILD_CMDS since it already includes RUSTFLAGS but also CARGO_HOME. Fixes: error: could not compile `rustdoc-tool` (bin "rustdoc_tool_binary") due to previous error [1] https://gitlab.com/buildroot.org/buildroot/-/blob/2024.02-rc1/package/pkg-cargo.mk#L165 Signed-off-by: Romain Naour <romain.naour@smile.fr> Signed-off-by: Yann E.
