With the recent cairo bugfix, we can now switch to using cairo for
rendering i3bar per default by raising the minimum version of cairo
to 1.14.4, if this cairo version is available.
resolves#2048
* common.mk: use -lsocket -liconv -lgen on Illumos/Solaris
* mkdirp: return int and accept a mode argument
* use i3's mkdirp on everything except Illumos
The Makefiles should put binaries in $(EXEC_PREFIX) and
architecture-independent files in $(PREFIX). Also a user may have a
prefixed- pkg-config, as in the case of cross compiling on Exherbo
Linux, so respect the well-accepted $(PKG_CONFIG) variable for this
purpose.
This removes our last dependency on Xlib! :)
(Okay, an Xlib dependency still comes in through other libraries that we
link against, but it’s not us. Our code is simpler by this change and
uses one less connection to X11.)
See also commit 0e752070ac2bed02d0858bbc450ddcee36e3b9b5, which broke
source code listings in gdb unless you cd into i3/src. This should give
us best of both :-).
This is useful for third-party scripts which require certain features
and want to error out cleanly when they are run with an old i3 version.
Additionally, i3 --version might be different from what’s actually
running (an old version of the binary), so i3-msg -t get_version will be
the best way to figure out the i3 version you are actually running from
this commit on.
CPPFLGES, CFLAGS and LDFLAGS should be user variables
We now provide default flags but use I3_*FLAGS flags for our own needed
flags
Also reoder lib flags a bit
The former two provide fallbacks in case $PAGER or $EDITOR is not set (which
might be more common than you think, because they have to be set in
~/.xsession, not in the shell configuration!) while the latter tries to launch
a terminal emulator. The scripts are most prominently used in i3-nagbar, which
alerts the user when the configuration is broken for some reason. Also,
i3-sensible-terminal is used in the default configuration.
This commit does not rely on the shell supporting ${PAGER:-less} anymore, which
is not the case for 'fish'.
