Linking error on WSL Ubuntu
EtoDemerzel0427 opened this issue · 10 comments
Thought it might be more appropriate to raise this in a separate issue. As you indicated previously, performance on Apple Silicon might not reflect the real performance considering the lack of AVX etc., so I am building mutable on my PC now. It is an Ubuntu 20.04 (in WSL), with LLVM-19.
I am building with libc++ and lld, other configurations are the same as the build/debug_shared settings in the setup document.

Sorry for so many environment setup problems on different platforms :(
No worries, we'll get you there ;)
We don't have the resources to test on many different platforms. So sorry for you being our Ubuntu test infra for now.
Can you please share the output of
$ echo | clang -v -x c++ -std=c++20 -o -
$ ld.lld --version
$ whereis gn # or `which gn` or `where gn` or whatever your shell supports
$ whereis fetch
This will help us diagnose the problem. Thanks
Hi, the outputs are as below:
$ echo | clang -v -x c++ -std=c++20 -o -

/home/wrhuang/codespace/depot_tools/fetchYes, I saw that doc, but is there a specific reason that I should build clang from source? I installed LLVM via apt.
What's LLVM/Clang at version "Ubuntu clang version 19.0.0"? 👀
The most recent release according to llvm.org is 17.0.6: https://releases.llvm.org/
Ubuntu is usually super far behind on releases. Like... years behind. That's why I can only suggest you build a recent compiler release. We rely on proper C++20 support, with an emphasis on proper ;)
Same goes for ld.lld.
gn and depot_tools are looking good. Sadly, that doesn't mean anything. Google tooling can be extremely flaky, failing for the weirdest reasons (rising tide, leap year, who knows...)
EDIT: Oh, so there's this: https://apt.llvm.org/ . So you have Clang nightly?
Yes, I actually wasn't aware that was nightly. I simply did:
wget -O - https://apt.llvm.org/llvm-snapshot.gpg.key | sudo apt-key add -
sudo add-apt-repository "deb http://apt.llvm.org/focal/ llvm-toolchain-focal main"and then installed llvm without specifying its version and it installed 19 automatically 😂. I didn't know it was nightly.
I would try stable version first to see if anything changed.
Hey @EtoDemerzel0427, any progress?
Hi @ImmanuelHaffner thanks for checking! I was distracted by other issues this week, so haven't yet. I may come back to this early next week.
Any progress?
I am not actively trying to fix this issue at this moment: we decided to prototype on Mac first and then move to other platforms. I do think it shouldn't be hard to fix. So I am closing this issue for now.
All right. Thanks for letting us know. Please don't refrain from reopening this issue or filing a new one when you want to revisit this. We are here to help :)
