Error when running mold on Manjaro: /usr/lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.33' not found

Hello!

I'm trying to use mold on Manjaro and receiving these errors:

$ cd ~/projects
$ git clone --recursive https://github.com/rui314/mold.git
$ cd mold
$ make submodules
$ make

$ build-webkit --gtk --debug --cmakeargs="-DUSE_LD_LLD=OFF -DUSE_LD_GOLD=OFF"

/home/twilco/projects/mold/mold: /usr/lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.33' not found (required by /home/twilco/projects/mold/mold)
/home/twilco/projects/mold/mold: /usr/lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.32' not found (required by /home/twilco/projects/mold/oneTBB/build/linux_intel64_gcc_cc10.2.0_libc2.33_kernel5.4.105_release/libtbb.so.2)

It looks like mold expects these .sos to be in the directories Ubuntu / apt-get puts them in (e.g. see the file listing for libc6-dev, depended on by Ubuntu's build-essential package). Neither /usr/lib/x86_64-linux-gnu nor /lib/x86_64-linux-gnu exists on my system, so I'm guessing Arch-based repos don't follow this pattern.

I do have glibc installed, just not in the place mold expects:

$ /lib/libc.so.6

I tried a symlink:

$ sudo mkdir /usr/lib/x86_64-linux-gnu
$ sudo ln -s /lib/libc.so.6 /usr/lib/x86_64-linux-gnu/libc.so.6

But get the exact same errors, so there must be more to it.

Have you tested mold on Arch-based distros yet?

Thanks for making this project -- excited to continue experimenting with it!

Though testing with your Rust example, mold seems to work fine:

cargo new mold-test
cd mold-teset
...edit .cargo/config.toml to what is in the linked comment...
cargo run
readelf -p .comment target/debug/mold-test

A simple CMake project also worked fine.

My original example is trying to build the GTK port of WebKit, which uses a Flatpak SDK for setting up build tools and running the build.

The problem is probably there, so I'm going to close this since it doesn't seem like a mold problem.
