From: Jakub Jirutka Date: Sat, 08 Aug 2016 19:56:00 +0200 Subject: [PATCH] Change rpath for rustc/rustdoc to rustlib/$TARGET/lib Rust installs two identical sets of *.so libraries into /usr/lib and /usr/lib/rustlib/$TARGET/lib. The former comes with the rustc component, /usr/bin/rustc and /usr/bin/rustdoc are linked against them. The latter comes with rust-std and are used for binaries dynamically linked against Rust libraries (usually compiler plugins, like clippy). These *.so libraries don't keep stable ABI, so it's better to treat them as private. Such libraries should not be exposed at standard paths like /usr/lib, but use rpath. This patch changes rpath for binaries of the rustc component to `$ORIGIN/../lib/rustlib/$TARGET/lib`. Duplicate libraries will be still installed into /usr/lib, but we can simply remove them when packaging.
