So one can have: DYLD_LIBRARY_PATH = /opt/Rust/0/lib/:/opt/Rust/1/lib/:/opt/Rust/2/lib/ My layout is like this: cd /opt; ls Rust/versions/*/*/lib/libnative-* Rust/versions/0f2ae7b932a9045f0d03ca35ff8cfc3fd939414e/rust-nightly-x86_64-apple-darwin/lib/libnative-1fb5e2c0-0.11.0-pre.dylib Rust/versions/21fd11fef66e9973bd424915b9ee958c0990af2b/rust-nightly-x86_64-apple-darwin/lib/libnative-4e7c5e5c.dylib Rust/versions/65395dc2bb240534c288bd60a5983538410af47d/rust-nightly-x86_64-apple-darwin/lib/libnative-35e04b6f-0.11.0.dylib Rust/versions/8d6cd8c1b95b2bb6d14008258e5e571552159f38/rust-nightly-x86_64-apple-darwin/lib/libnative-4e7c5e5c.dylib Rust/versions/a7b8824b2f8388705e4683b938fea442a663ebcb/rust-nightly-x86_64-apple-darwin/lib/libnative-4e7c5e5c.dylib > -- need different fixed per-project environments They will only need to care about executable path, which is something they would need to care about even if this change hadn't been made. > -- don't have permission to write into /usr/local (typically on shared > servers) Is is not a valid reason, they can unpack the tarball into any prefix. > -- don't want to have a mess in /usr/local Sure, so I personally put it under /opt/Rust/ >> As detailed in the meeting where this decision was made, Linux distros >> really dislike it when you mess with rpath; it's a deal-breaker in many >> cases. > > I don't know about all Linux distros, but apparently Ubuntu is OK about > rpath: > > $ objdump -x /usr/lib/jvm/java-7-openjdk-amd64/bin/java | grep RPATH > RPATH > $ORIGIN/../lib/amd64/jli:$ORIGIN/../lib/amd64:$ORIGIN/../jre/lib/amd64 Ubuntu is not the best example of how an OS should be built. It's probably a longstanding OpenJDK issue too, did you check? _______________________________________________ Rust-dev mailing list Rust-dev@mozilla.org https://mail.mozilla.org/listinfo/rust-dev
