Fix rpath for libdir is specified ## What does this PR try to resolve? When building the Rust toolchain with `--libdir=lib64`, the executable tools such as `rustc` cannot find shared libraries. ```bash ./configure --prefix=/ --libdir=lib64 DESTDIR=/tmp/rust ./x.py install ``` ``` $ /tmp/rust/bin/rustc rustc: error while loading shared libraries: librustc_driver-13f1fd1bc7f7000d.so: cannot open shared object file: No such file or directory ``` This issue is caused by the link args `-Wl,rpath` being different from `--libdir`. ``` $ readelf -d /tmp/rust/bin/rustc | grep RUNPATH 0x000000000000001d (RUNPATH) Library runpath: [$ORIGIN/../lib] ``` ## How to resolve? When setting the rpath, get it from sysroot libdir relative path. After this patch: ``` $ readelf -d /tmp/rust/bin/rustc | grep RUNPATH 0x000000000000001d (RUNPATH) Library runpath: [$ORIGIN/../lib64] ```
This directory contains some source code for the Rust project, including:
- The bootstrapping build system
- Various submodules for tools, like cargo, tidy, etc.
For more information on how various parts of the compiler work, see the rustc dev guide.
