Description Greg V 2020-12-01 18:46:05 UTC
graphics/libdrm has this:

MANPAGES_USE=		GNOME=libxslt:build

Obviously the intention is to use libxslt only during the build.

Now, gnome.mk has:

libxslt_USE_GNOME_IMPL=	libxml2

and the way these implications are handled is (minus the unknown check):

. for component in ${USE_GNOME:C/^([^:]+).*/\1/}
_USE_GNOME+=	${${component}_USE_GNOME_IMPL} ${component}
. endfor

Oops, the :build flag is lost (literally deleted by the :C/../../ and never handled), not propagated, so we basically have USE_GNOME=libxml2 — so this ends up in the pkg +MANIFEST:

  "deps": {
    "libpciaccess": {
      "origin": "devel/libpciaccess",
      "version": "0.16"
    "libxml2": {
      "origin": "textproc/libxml2",
      "version": "2.9.10_1"
But libdrm does not actually depend on libxml2 at runtime!!


How I noticed this is that poudriere fails to install anything that depends on libdrm:

===>   mesa-devel-20.3.b.786 depends on package: libva>0 - not found
===>   Installing existing package /packages/All/libva-2.9.1.tzst

pkg-static: Missing dependency 'libxml2'

…granted, it *shouldn't* fail, it should find the libxml2 dependency, which of course *was* added to RUN_DEPENDS at the port level, so something went wrong in poudriere for me here. but I'm glad it did, because idk if anyone would've found that issue otherwise.

To be honest, this looks like a bug in gnome.mk rather than libdrm.
Comment 2 Greg V 2020-12-02 01:05:14 UTC
(In reply to Niclas Zeising from comment #1)

Yes – that's why the title begins with gnome.mk :)

I wonder how bugzilla decided to assign to x11. First word of the text also counts, not just the title?

pkg info -d libdrm
Seems fixed.
