Hi! See https://reviews.freebsd.org/D22210 for details. The patch attempts to silence spurious warnings about needing USES=xorg in certain conditions. Patch for exp-run is in the review. Thanks!
A commit references this bug: Author: zeising Date: Wed Nov 6 19:02:43 UTC 2019 New revision: 516921 URL: https://svnweb.freebsd.org/changeset/ports/516921 Log: Mk/Uses: Add USES+=xorg when including xorg.mk Add USES+=xorg to the places where MK/Uses/xorg.mk is included from other files in the Uses infrastructure. This is done to silence an erroneous warning about USES=xorg not being set when using USES=gl, motif or xorg-cat, even when it's included from the framework. This is a different proposal than what was originally suggested in pr 241627 and https://reviews.freebsd.org/D22210 . PR: 238988, 241627 Discussed with: mat MFH: 2019Q4 Differential Revision: https://reviews.freebsd.org/D22210 Changes: head/Mk/Uses/gl.mk head/Mk/Uses/motif.mk head/Mk/Uses/xorg-cat.mk
Closing this, since a different solution has been committed.
