Description

I am classifying the following as a master source regression and not a dports issue because multimedia/ffmpegthumbnailer was building until yesterday without issue in a hacked version of pkgsrc I have been using. Some change from October 25 breaks building both on pkgsrc and dports.

To demonstrate the problem using dports, update to master source through:

commit 62a4e7957a736b4de38938b02fa7eb9b45bc5d0d
Date: Tue Oct 25 23:04:45 2016 +0200

if_iwm - Switch arguments from iwm_node* to iwm_vap* in if_iwm_power.c.

Now build dports git, xorg, xfce4 from scratch using:

make clean && make NO_DIALOG=yes install clean

Now try building for multimedia/ffmpegthumbnailer. I would guess one would obtain an error similar to:

The /etc/make.conf I used is a simple:

CFLAGS+=-g
STRIP=

WITH_PKGNG=yes
DISABLE_VULNERABILITIES=yes
