Rocq Build Troubleshoot

Use this skill when a .v file fails to compile and the goal is a minimal targeted fix.

Scope

• Repository: RocqOfRust
• Commands use project flags: -R . RocqOfRust -impredicative-set
• Prefer single-file checks first, then dependency checks.

Workflow

1. Reproduce exactly:

coqc -R . RocqOfRust -impredicative-set path/to/file.v

1. If error references missing module/loadpath:

• Add explicit Require Import ... in the failing file.
• Do not rely on removed aggregator modules.
• Prefer per-function imports in revm/revm_interpreter/instructions/{links,simulate}/....

1. If error is argument-order/type mismatch in run_* call:

• Compare the local run_* instance signature in .../links/....
• Align call order exactly; remove placeholder _ arguments unless required by implicit params.

1. If Range literals fail type inference:

• Use record notation with typed zeros:

{|
  Range.start := (0 : usize);
  Range.end_ := (0 : usize)
|}

1. Recompile touched file(s):

coqc -R . RocqOfRust -impredicative-set path/to/file.v

1. Optional dependency sanity check:

make path/to/file.vo

Guardrails

• Keep fixes minimal and local.
• Do not reintroduce removed aggregators.
• Preserve Admitted where the project intentionally keeps placeholders.
• If proving _eq fails, check semantic alignment before attempting Qed.
