Linux release binary requires glibc 2.38+, fails on Amazon Linux 2023 and older distros

[devrel-ditto]

Problem

The Linux release binary (platform-cli_1.0.1_linux_amd64.tar.gz) dynamically links against glibc and requires version 2.38+:

platform-cli: /lib64/libc.so.6: version `GLIBC_2.38' not found (required by platform-cli)

This is because ubuntu-latest on GitHub Actions is Ubuntu 24.04 (glibc 2.39). The binary won't run on:

• Amazon Linux 2023 (glibc 2.34)
• Ubuntu 22.04 (glibc 2.35)
• Debian 12 (glibc 2.36)
• RHEL 9 / Rocky 9 (glibc 2.34)

Root Cause

The release workflow uses CGO_ENABLED=1 (required for blst and libevm) with the default dynamic linker on ubuntu-latest. The resulting binary is dynamically linked against the CI runner's glibc.

Suggested Fix

Statically link the Linux binaries using musl. In .github/workflows/release.yml, for the Linux amd64 build:

1. Install musl-tools: sudo apt-get install -y musl-tools
2. Set CC=musl-gcc
3. Add -extldflags '-static' to ldflags

This produces a fully static binary that runs on any Linux distro regardless of glibc version.

Environment

• platform-cli v1.0.1, linux/amd64 release binary
• Amazon Linux 2023 (glibc 2.34, kernel 6.1)
• Workaround: building from source works fine
