The llvm-18 Ubuntu Jammy (22.04) LTS binary packages don't include LLVMgold.so #87553

joshuaehill · 2024-04-03T20:33:58Z

The llvm-18 release binary packages for Ubuntu Jammy (22.04) published on the LLVM Debian/Ubuntu nightly packages don't seem to include the LLVMgold.so plugin required for LTO support.

In prior versions, this was included in the linker-tools package, but this file is not presently included in the llvm-18-linker-tools package.

Using the current package set for llvm-18 when using LTO, the linker complains:
/usr/bin/ld: /usr/lib/llvm-18/bin/../lib/LLVMgold.so: error loading plugin: /usr/lib/llvm-18/bin/../lib/LLVMgold.so: cannot open shared object file: No such file or directory

The text was updated successfully, but these errors were encountered:

This seems to have been mentioned before, and may be related to #84271.

MaskRay · 2024-04-03T22:27:13Z

Thanks for the report. I created #87567

MaskRay · 2024-04-03T22:28:58Z

In prior versions, this was included in the linker-tools package, but this file is not presently included in the llvm-18-linker-tools package.

@sylvestre Do you know who maintains the Ubuntu packages? It seems that they started to use cmake -DLLVM_INSTALL_TOOLCHAIN_ONLY=on ?

sylvestre · 2024-04-03T22:40:37Z

this is me and no, we don't use LLVM_INSTALL_TOOLCHAIN_ONLY
grep on https://salsa.debian.org/pkg-llvm-team/llvm-toolchain/-/blob/18/debian/rules return 0

MaskRay · 2024-04-04T17:37:56Z

I confirm that the llvm-17-linker-tools package contains LLVMgold.so while llvm-18-linker-tools doesn't.

Landed #87567 to install LLVMgold.so (like we install libLTO.so) in LLVM_INSTALL_TOOLCHAIN_ONLY=on builds but @sylvestre said it might be unrelated?

I was about to report the similar issue to Debian packages, because this affects my CI build as well (see this build log). Now I cannot use LLVM-18 with LTO anymore.

By the way, the fastest way to verify this is to see this page:
https://packages.debian.org/sid/amd64/llvm-18-linker-tools/filelist
and compare with this:
https://packages.debian.org/sid/amd64/llvm-17-linker-tools/filelist
or this:
https://packages.debian.org/experimental/amd64/llvm-19-linker-tools/filelist

And see the LLVMgold.so file is missing.

MaskRay · 2024-04-27T18:14:49Z

@sylvestre ^^

sylvestre · 2024-04-29T08:49:12Z

yeah, it is now fixed.
I tried to build llvm-toolchain with mold and it caused llvmgold not to be generated?!
@MaskRay do you think it is a LLVM bug ?

Explorer09 · 2024-04-29T12:32:03Z

Can you guys tell us which version of the package will start including LLVMgold.so back? Because I need to estimate when the llvm-18 build in GitHub Actions CI will work again with LTO.

llvm-18-linker-tools_18.1.3~%2B%2B20240322073153%2Bef6d1ec07c69-1~~exp1~~20240322193300.86_amd64 surely doesn't have the LLVMgold.so.

i retriggered this build for 18, it should be available in a few hours

This is going to be another clang-format war around lambdas. Grrr llvm/llvm-project#87553 Remove llvm-linker package when the above is resolved Change-Id: Iea0776aaa7edd483fa395e23de25ebf5a6288f71 Signed-off-by: Ed Tanous <ed@tanous.net>

@sylvestre hi, could you please also fix ubuntu 24.04 support? See #90536

clundquist-stripe · 2024-05-01T20:59:39Z

@yujincheng08
libclang-rt-dev provides these libraries on 24.04
I think it is a meta package for https://packages.ubuntu.com/eu/noble/libdevel/libclang-rt-18-dev specifically as of this writing.

@clundquist-stripe I have tried to install libclang-rt-18-dev in Ubuntu 24.04. It still does not contain LLVMgold.so.

After some comparison, I found that llvm-17-linker-tools contains LLVMgold.so, while llvm-17-linker-tools not.

https://packages.ubuntu.com/eu/noble/amd64/llvm-17-linker-tools/filelist

Maybe the latest fix is not built yet for 24.04?

https://bugs.launchpad.net/ubuntu/+source/llvm-toolchain-18/+bug/2064187 ("llvm-18-linker-tools does not include LLVMgold.so") seems related.

sylvestre · 2024-05-09T07:19:36Z

@MaskRay indeed :/ this is the autosync from Debian to Ubuntu. I am following up with Ubuntu to get a fix as noble is a LTS

illwieckz · 2024-05-10T20:20:05Z

I don't know if it's fixed for Ubuntu Jammy 22.04, but I confirm this is not fixed yet for Mantis 23.10:

[packaging] clang-18 from apt.llvm.org on Ubuntu 23.10 mantic is missing LLVMgold.so and fails to link with LTO #90810

Ubuntuu has broken LLVM 18 packages, LTO is busted. No ETA on a fix, but the problem is well known. Previous experience indicates that a fix may take many months or never come at all, so disabling LTO in CI for Ubuntu builds for now, until they get their act together. https://bugs.launchpad.net/ubuntu/+source/llvm-toolchain-18/+bug/2064187 llvm/llvm-project#87553 Signed-off-by: Jeffrey H.
