rust-lld fails with "dyld: Library not loaded: @rpath/libLLVM.dylib" on 1.30.0-nightly (02cb8f2a4 2018-08-29) #53813

Searching the source tree for rpath turns up some humorous comments...

           // Dealing with rpath here is a little special, so let's go into some 
        
           // detail. First off, `-rpath` is a linker option on Unix platforms 
        
           // which adds to the runtime dynamic loader path when looking for 
        
           // dynamic libraries. We use this by default on Unix platforms to ensure

           //

           // option is the compiler's current interface to generating an rpath. 
        
           // Unfortunately it doesn't quite suffice for us. The flag currently 
        
           // takes no value as an argument, so the compiler calculates what it 
        
           // should pass to the linker as `-rpath`. This unfortunately is based on 
        
           // the **compile time** directory structure which when building with 
        
           // Cargo will be very different than the runtime directory structure.

I have this issue too!

GabrielMajeri · 2018-08-30T15:03:06Z

I believe this issue is caused by 3cf6f0d: "Link LLVM tools dynamically...".

It only enables dynamic linking libllvm on Linux and Mac OS, and since no Windows users complained so far I can only assume it's the probable cause.

Speaking of which, it might be a good idea to add testing the built LLVM tools / LLD to Rust's CI, to ensure issues like this are caught earlier on.

japaric · 2018-08-30T15:14:35Z

@alexcrichton @michaelwoerister this may have been caused by #53245.

japaric · 2018-08-30T15:46:14Z

@GabrielMajeri it seems that libLLVM.so is provided by the llvm-tools-preview component which I have installed. Try running rustup component add llvm-tools-preview and see if that fixes LLD.

@alexcrichton @michaelwoerister it sounds like libLLVM.so should always by shipped with the compiler since rust-lld depends on it.

GabrielMajeri · 2018-08-30T16:09:02Z

@japaric I installed them, but it didn't help. The LLVM tools do seem to work, and I now have the libLLVM.so library in the <rust-sysroot>/lib directory.

However, checking rust-lld's RPATH shows $ORIGIN/../lib,
i.e. it points to <rust-sysroot>/lib/rustlib/x86_64-unknown-linux-gnu/lib/.

Doing

ln -s $(rustc --print sysroot)/lib/libLLVM-7.so $(rustc --print sysroot)/lib/rustlib/x86_64-unknown-linux-gnu/lib/

does (temporarily) fix the problem.

alexcrichton · 2018-08-30T16:44:02Z

I'm working on a fix for this!

A recent change (rust-lang#53245) started to build LLVM with ThinLTO enabled and to ensure that compile times are kept down it builds LLVM dynamically by default to ensure that all the various LLVM tools aren't redoing all that optimization work. This means, however, that all LLVM tools depend on LLVM's dynamic library by default. While the LLVM tools and LLDB components were updated to include the shared library we accidentally forgot about LLD, included with the main rustc component. LLD also links dynamically to LLVM and ships a non-working binary right now because of this! This commit updates our distribution to ship the LLVM dynamic library with the compiler libraries. While not technically needed for rustc itself to operate (right now) it may be needed for LLD, and otherwise it serves as a good basis for the other LLVM tools components to work with as well. This should... Closes rust-lang#53813

alexcrichton · 2018-08-30T16:50:53Z

@japaric's diagnosis is spot on and this should be fixed in #53828

To recap, interim fixes include:

rustup component add llvm-tools-preview --toolchain nightly
Downgrading to an older nightly temporarily

@thehappycoder wasm-bindgen only just had all of the features it relies on stabilize, so it is still nightly-only until those newly-stabilized features ride the release trains from nightly -> beta -> stable.

thehappycoder · 2018-08-31T21:16:11Z

@fitzgen thanks for pointing out. I just noticed that it is using nightly version. I am new to rust, so I have no idea how to rollback to previous nightly version to use as a workaround.

For future reference, you can use rustup to install any nightly, for instructions see the rustup github page.

This commit tweaks the layout of a few components that we distribute to hopefully fix across all platforms the recent issues with LLD being unable to find the LLVM shared object. In rust-lang#53245 we switched to building LLVM as a dynamic library, which means that LLVM tools by default link to LLVM dynamically rather than statically. This in turn means that the tools, at runtime, need to find the LLVM shared library. LLVM's shared library is currently distributed as part of the rustc component. This library is located, however, at `$sysroot/lib`. The LLVM tools we ship are in two locations: * LLD is shipped at `$sysroot/lib/rustlib/$host/bin/rust-lld` * Other LLVM tools are shipped at `$sysroot/bin` Each LLVM tool has an embedded rpath directive indicating where it will search for dynamic libraries. This currently points to `../lib` and is presumably inserted by LLVM's build system. Unfortunately, though, this directive is only correct for the LLVM tools at `$sysroot/bin`, not LLD! This commit is targeted at fixing this situation by making two changes: * LLVM tools other than LLD are moved in the distribution to `$sysroot/lib/rustlib/$host/bin`. This moves them next to LLD and should position them for... * The LLVM shared object is moved to `$sysroot/lib/rustlib/$host/lib` Together this means that all tools should natively be able to find the shared object and the shared object should be installed all the time for the various tools. Overall this should... Closes rust-lang#53813

In #53245 we switched to building LLVM as a dynamic library, which means that LLVM tools by default link to LLVM dynamically rather than statically. This in turn means that the tools, at runtime, need to find the LLVM shared library. LLVM's shared library is currently distributed as part of the rustc component. This library is located, however, at `$sysroot/lib`. The LLVM tools we ship are in two locations: * LLD is shipped at `$sysroot/lib/rustlib/$host/bin/rust-lld` * Other LLVM tools are shipped at `$sysroot/bin` Each LLVM tool has an embedded rpath directive indicating where it will search for dynamic libraries. This currently points to `../lib` and is presumably inserted by LLVM's build system. Unfortunately, though, this directive is only correct for the LLVM tools at `$sysroot/bin`, not LLD! This commit is targeted at fixing this situation by making two changes: * LLVM tools other than LLD are moved in the distribution to `$sysroot/lib/rustlib/$host/bin`. This moves them next to LLD and should position them for... * The LLVM shared object is moved to `$sysroot/lib/rustlib/$host/lib` Together this means that all tools should natively be able to find the shared object and the shared object should be installed all the time for the various tools. Overall this should... Closes #53813

Thanks for your super-fast help, @alexcrichton! 🚀

For anyone wondering, the osx fix is not on the current nightly – rustc 1.30.0-nightly (6e0f1cc15 2018-09-05) – yet.

TejasQ · 2018-09-06T08:22:13Z

Why's this issue closed then? 🤔

Why's this issue closed then? 🤔

Is it because the fix will be in tomorrow's nightly build?

alexcrichton · 2018-09-06T16:30:13Z

Yes this fix missed last night's nightly but it should be in tonight's nightly!

kzvi · 2018-09-07T01:09:19Z

I'm still getting this error with rustc 1.30.0-nightly (a8c11d216 2018-09-06).

alexcrichton · 2018-09-07T02:07:41Z

Looks like there's at least one more bug to fix -- #54018

thehappycoder · 2018-09-08T09:39:54Z

Finally, I managed to compile on a mac with the latest nightly build of rust!
