Compile CompCert

Overview

CompCert is a formally verified C compiler built with Coq proof assistant. Building it from source requires careful attention to dependency versions, particularly Coq compatibility, and resource constraints in containerized environments.

Pre-Build Investigation (Critical First Step)

Before installing any dependencies, download and examine CompCert's requirements:

1. Download CompCert source first

   • Obtain the source tarball or clone the repository
   • Check the configure script for version requirements: grep -i "coq" configure
   • Review README or INSTALL files for dependency specifications

2. Identify exact Coq version requirements

   • CompCert has strict Coq version bounds (e.g., CompCert 3.13.1 requires Coq ≤ 8.16.1)
   • Installing an incompatible Coq version wastes significant time and resources
   • Check both minimum and maximum supported versions
