GCC toolchain targeting older glibc versions, designed for building Linux binaries that run across a wide range of distributions. Intended for use inside a Docker container running Ubuntu 24.04 or later. This toolchain is built using Crosstool-NG.
The usual method for producing portable Linux binaries is to compile them on an outdated distribution (e.g., CentOS 7).
This repository provides a modern alternative: a GCC toolchain configured to target an older glibc, ensuring compatibility and preventing errors like:
/lib64/libc.so.6: version `GLIBC_2.XX' not found

If you prefer not to build the toolchain yourself, a precompiled GCC toolchain for each supported architecture can be downloaded from the releases page.
