This commit disables rustc's emission of rpath attributes into dynamic libraries and executables by default. The functionality is still preserved, but it must now be manually enabled via a `-C rpath` flag. This involved a few changes to the local build system: * --disable-rpath is now the default configure option * Makefiles now prefer our own LD_LIBRARY_PATH over the user's LD_LIBRARY_PATH in order to support building rust with rust already installed. * The compiletest program was taught to correctly pass through the aux dir as a component of LD_LIBRARY_PATH in more situations. The major impact of this change is that neither rustdoc nor rustc will work out-of-the-box in all situations because they are dynamically linked. It must be arranged to ensure that the libraries of a rust installation are part of the LD_LIBRARY_PATH. The default installation paths for all platforms ensure this, but if an installation is in a nonstandard location, then configuration may be necessary. Additionally, for all developers of rustc, it will no longer be possible to run $target/stageN/bin/rustc out-of-the-box. The old behavior can be regained through the `--enable-rpath` option to the configure script. This change brings linux/mac installations in line with windows installations where rpath is not possible. Closes #11747 [breaking-change] |
