[build issue] version GLIBCXX_3.4.26 not found when building from source

[dlee992]

Hi, I tried to follow the installation cmds in the doc, for building triton from source.

But Afterwards, I met this error:

/home/dli/.triton/llvm/llvm-4017f04e-ubuntu-x64/bin/mlir-tblgen: /lib64/libstdc++.so.6: version 'GLIBCXX_3.4.26' not found (required by /home/dli/.triton/llvm/llvm-4017f04e-ubuntu-x64/bin/mlir-tblgen)

Looks like triton downloads a LLVM static library which is built with GLIBCXX_3.4.26, but my local libstdc++.so.6 only supports to maximum GLIBCXX_3.4.25. (And in fact my OS is Rocky, not ubuntu)

A limitation in my side is I don't have permissions to upgrade system libstdc++ in my machine, then what should I do? e.g.,

1. How to choose another alternative LLVM static library with a correct SHA?
2. How to build the LLVM library from source required by triton, instead of downloading a built static one?

Any comments, links, or guidances are welcome! Thanks!

The fix used in pytorch (pytorch/pytorch#121556) was to use conda install sysroot_linux-64=2.17 libstdcxx-ng=12.3.0 which gives particular versions of GLIBC and GLIBCXX.

I tried this way provided by Peter, but didn't work for me in local/native hosts.
I will retry to build it in docker to make env configuration easier.

I think it can be solved by Peter's suggestion.
