Thanks for the investigation and the patch, Lucas.
Ugh, this one is kind of messy :-/. I'm not a fan of using d/not-
installed; I think it tends to hide problems that can prove to be
important.
I spent some time trying to figure out why this change works on Debian
but not on Ubuntu. When I compared Debian's build logs against
Ubuntu's, I noticed this difference:
Debian:
checking Directory to install systemd user unit files... Package systemd
was not found in the pkg-config search path.
Ubuntu:
checking Directory to install systemd user unit files...
/usr/lib/systemd/user
Upon investigating a bit more, I noticed that Debian's systemd doesn't seem to
ship with a pkg-config, whereas it does in Ubuntu. So, I looked into
redshift's configure.ac and found this:
# Check for systemd
PKG_PROG_PKG_CONFIG
AC_MSG_CHECKING([Directory to install systemd user unit files])
AC_ARG_WITH([systemduserunitdir],
[AS_HELP_STRING([--with-systemduserunitdir=<dir>],
[Directory for systemd user unit files])],
[], [with_systemduserunitdir=$($PKG_CONFIG
--variable=systemduserunitdir systemd)])
AS_IF([test -n "$with_systemduserunitdir" -a "x$with_systemduserunitdir" !=
xno], [
AC_SUBST([systemduserunitdir], [$with_systemduserunitdir])
AC_MSG_RESULT([$systemduserunitdir])
enable_systemd=yes
], [
AC_MSG_RESULT([not enabled])
enable_systemd=no
])
AM_CONDITIONAL([ENABLE_SYSTEMD], [test "x$enable_systemd" != xno])
You can see that there is an "else" branch (on AC_ARG_WITH) which accounts for
disabling systemd support. That's good. I was also able to verify that
Makefile.am takes ENABLE_SYSTEMD into account.
Having said all that, I think a better approach to this bug would be:
