GLIBC_2.32' not found: Troubleshooting the Canonical Error in Lean

As a Lean user, you may have encountered the error GLIBC_2.32' not found when trying to import the Canonical package. This error can be frustrating, especially when you've made no changes to your code or package versions. In this article, we'll delve into the possible causes of this error and provide step-by-step solutions to get you back up and running with Canonical.

The error message error loading library, /lib/x86_64-linux-gnu/libc.so.6: version GLIBC_2.32' not found (required by ././.lake/packages/Canonical/.lake/build/lib/libcanonical.so)indicates that the librarylibcanonical.sois trying to link against a version of the C standard library (libc) that is not available on your system. Specifically, it's looking for a version of libc that includes theGLIBC_2.32` symbol, which is not present in your system's libc.

Let's take a closer look at your lakefile.lean:

import Lake
open Lake DSL

package «lean-class» where
  -- Settings applied to both builds and interactive editing
  leanOptions := #[
    ⟨`pp.unicode.fun, true⟩ -- pretty-prints `fun a ↦ b`
  ]
  -- add any additional package configuration options here
  moreLinkArgs := #[
    "-L./.lake/packages/LeanCopilot/.lake/build/lib",
    "-lctranslate2"
  ]

require mathlib from git
  "https://github.com/leanprover-community/mathlib4.git" @ "v4.18.0"

@[default_target]
lean_lib «LeanClass» where
  -- add any library configuration options here

require Canonical from git
  "https://github.com/chasenorman/CanonicalLean.git"

require LeanCopilot from git "https://github.com/lean-dojo/LeanCopilot.git" @ "v4.18.0"

Your lakefile is importing the Canonical package from a git repository, which suggests that the issue may be related to the version of Canonical you're using.

The output of ldd --version on your system is:

(base) vilin@doppio:~/lean-class$ ldd --version
ldd (Ubuntu GLIBC 2.31-0ubuntu9.17) 2.31

This indicates that your system is using an older version of the C standard library (libc), which is version 2.31. This may be the root cause of the error, as the Canonical package is trying to link against a version of libc that is not available on your system.

Based on the analysis above, here are some troubleshooting steps you can take:

  1. Update your system's libc: If your system is using an older version of libc, you may need to update it to a version that includes the GLIBC_2.32 symbol. You can check the Ubuntu package repository for updates to the libc package.
  2. Reinstall Canonical: Try reinstalling the Canonical package from the git repository to see if that resolves the issue.
  3. Check the LeanCopilot version: As you mentioned, you think the issue may be related to the LeanCopilot version. Try updating LeanCopilot to the latest version to see if that resolves the issue.
  4. Check the Canonical version: Try updating the Canonical package to the latest version to see if that resolves the issue.

The GLIBC_2.32' not found error can be frustrating, but by analyzing the lakefile and the ldd version, we can identify the possible causes of the error. By following the troubleshooting steps outlined above, you should be able to resolve the issue and get back up and running with Canonical.

GLIBC_2.32' not found: Troubleshooting the Canonical Error in Lean - Q&A

In our previous article, we explored the possible causes of the GLIBC_2.32' not found error when trying to import the Canonical package in Lean. We also provided step-by-step solutions to help you troubleshoot and resolve the issue. In this article, we'll answer some frequently asked questions (FAQs) related to the GLIBC_2.32' not found error and provide additional guidance to help you overcome this challenge.

A: The GLIBC_2.32 symbol is a part of the C standard library (libc) that is required by the Canonical package. Specifically, it's a version of the libc that includes the GLIBC_2.32 symbol, which is not present in your system's libc.

A: Your system's libc version is not compatible with the Canonical package because it's an older version that doesn't include the GLIBC_2.32 symbol. To resolve this issue, you need to update your system's libc to a version that includes this symbol.

A: To update your system's libc, you can follow these steps:

  1. Check the Ubuntu package repository for updates to the libc package.
  2. Run the command sudo apt update to update the package list.
  3. Run the command sudo apt install libc6 to install the latest version of libc.
  4. Run the command ldd --version to verify that the libc version has been updated.

A: If you're using a different Linux distribution, you may need to update the libc package using the package manager specific to your distribution. For example, if you're using Fedora, you can use the dnf package manager to update the libc package.

A: Yes, you can try using a different version of the Canonical package. However, be aware that this may introduce other issues or dependencies that you need to resolve.

A: To check the version of the Canonical package, you can use the following command:

git log -1 --format=%H

This will display the commit hash of the latest version of the Canonical package.

A: Yes, you can try using a different version of the LeanCopilot package. However, be aware that this may introduce other issues or dependencies that you need to resolve.
