Since even libc++.dylib is now built with an @rpath install name by cmake by default, I propose to extend ldwrapper in binutils-config to use -rpath on macOS similar to other systems. This way prefix system dirs are unconditionally added to all binaries' rpath. # otool -L usr/lib/libc++.dylib usr/lib/libc++.dylib: @rpath/libc++.1.dylib (compatibility version 1.0.0, current version 1.0.0) /usr/lib/libc++abi.dylib (compatibility version 1.0.0, current version 400.7.0) @rpath/libc++abi.1.dylib (compatibility version 1.0.0, current version 1.0.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1252.0.0) # otool -l usr/bin/cmake | grep LC_LOAD_DYLIB\\\|\ name\\\|LC_RPATH\\\|path name /usr/lib/dyld (offset 12) cmd LC_LOAD_DYLIB name /Users/michael/nobak/gentoo/usr/lib/libexpat.1.dylib (offset 24) cmd LC_LOAD_DYLIB name /Users/michael/nobak/gentoo/usr/lib/libz.1.dylib (offset 24) cmd LC_LOAD_DYLIB name /Users/michael/nobak/gentoo/usr/lib/libarchive.13.dylib (offset 24) cmd LC_LOAD_DYLIB name /Users/michael/nobak/gentoo/usr/lib/libcurl.4.dylib (offset 24) cmd LC_LOAD_DYLIB name /Users/michael/nobak/gentoo/usr/lib/libuv.1.dylib (offset 24) cmd LC_LOAD_DYLIB name /Users/michael/nobak/gentoo/usr/lib/librhash.0.dylib (offset 24) cmd LC_LOAD_DYLIB name /System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation (offset 24) cmd LC_LOAD_DYLIB name @rpath/libc++.1.dylib (offset 24) cmd LC_LOAD_DYLIB name /usr/lib/libSystem.B.dylib (offset 24) cmd LC_RPATH path /Users/michael/nobak/gentoo/usr/lib (offset 12) cmd LC_RPATH path /Users/michael/nobak/gentoo/lib (offset 12) Reproducible: Always
Created attachment 511956 [details] Add -rpath support to ldwrapper Extend ldwrapper to inject -rpath options into the linker command line on darwin as well. Only do so if ld64 would not refuse to accept them. This can happen if the output type doesn't support it (static, kext, ...) or the deployment target is unspecified or did not support -rpath yet (< 10.5). The latter is not usually a problem since portage (MACOSX_DEPLOYMENT_TARGET) and clang (-macosx_version_min) always set the deployment target explicitly.
