You should be able to use gexps, e.g. #$output (see <https://guix.gnu.org/manual/devel/en/html_node/G_002dExpressions.html> for more details). That is actually the preferred way now, though there are still instances of assoc-ref. I believe the commit in question is <https://git.savannah.gnu.org/cgit/guix.git/commit?id=7d873f194ca69d6096d28d7a224ab78e83e34fe1>. > I think the issue is in qt using different system than build systems such > as cmake or gnu.

Perhaps qt-build purposefully left the older procedure behind as it should have much fewer dependents (which may rely on the old assoc-ref)? Hope that helps! The short of it is to use gexps :) John
