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 libraries require OCaml and sometimes also Camlp5 or findlib. The exact
versions that were used to build Coq are saved in the
coq.ocaml and coq.camlp5 and
coq.findlib attributes.
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}";
