Coq
Coq libraries should be installed in
$(out)/lib/coq/${coq.coq-version}/user-contrib/. Such
directories are automatically added to the $COQPATH
environment variable by the hook defined in the Coq derivation.
Some extensions (plugins) might require OCaml and sometimes other OCaml
packages. The coq.ocamlPackages attribute can be used to
depend on the same package set Coq was built against.
Coq libraries may be compatible with some specific versions of Coq only. The
compatibleCoqVersions attribute is used to precisely
select those versions of Coq that are compatible with this derivation.
Here is a simple package example. It is a pure Coq library, thus it depends
on Coq. It builds on the Mathematical Components library, thus it also takes
mathcomp as buildInputs. Its
Makefile has been generated using
coq_makefile so we only have to set the
$COQLIB variable at install time.
{ stdenv, fetchFromGitHub, coq, mathcomp }:
stdenv.mkDerivation rec {
name = "coq${coq.coq-version}-multinomials-${version}";
version = "1.0";
src = fetchFromGitHub {
owner = "math-comp";
repo = "multinomials";
