FAQPage Schema

How do I build CompCert from source code?▼

To build CompCert, you configure the source code and execute the compilation process using opam to manage the OCaml environment. This process produces a formally verified C compiler ready for installation.

What OCaml and Coq versions are compatible for compiling CompCert?▼

CompCert requires specific, compatible versions of Coq and Menhir installed via the opam package manager. Managing these strict proof assistant dependencies correctly prevents version conflicts during the formal verification build.

Why does my CompCert build fail with Coq or OCaml errors?▼

CompCert builds often fail due to Coq and OCaml version conflicts or memory errors during compilation. Troubleshooting involves using opam to install compatible dependency versions and resolving memory constraints during the proof assistant execution.

Do I need opam to install Coq and Menhir for CompCert?▼

Yes, you need opam to set up the OCaml environment and install compatible versions of Coq and Menhir. This dependency management is required to satisfy the formal verification toolchain setup for CompCert.

How do I set up a formal verification toolchain for a C compiler?▼

Setting up a formal verification toolchain for CompCert involves configuring OCaml environments with opam and installing Coq proof assistant dependencies. This ensures the strict requirements for building verified software are met.

What is the best way to configure CompCert before compilation?▼

The best way to configure CompCert is to ensure all OCaml and Coq dependencies are correctly installed via opam first. Proper configuration addresses version compatibility and prevents memory errors during the subsequent compilation phase.
