In dist tarballs, the version is stored in the I3_VERSION and VERSION files.

Generic flags

Default CFLAGS that users should be able to override

ifeq ($(DEBUG),1)

Extended debugging flags, macros shall be available in gcc

CFLAGS ?= -pipe -gdwarf-2 -g3 else CFLAGS ?= -pipe -O2 -freorder-blocks-and-partition endif

Default LDFLAGS that users should be able to override

LDFLAGS ?= $(as_needed_LDFLAG)

Common CFLAGS for all i3 related binaries

I3_CFLAGS = -std=c99 I3_CFLAGS += -Wall

unused-function, unused-label, unused-variable are turned on by -Wall

We don’t want unused-parameter because of the use of many callbacks

I3_CFLAGS += -Wunused-value I3_CFLAGS += -Iinclude

I3_CPPFLAGS = -DI3_VERSION=\"${I3_VERSION}\" I3_CPPFLAGS += -DMAJOR_VERSION=${MAJOR_VERSION} I3_CPPFLAGS += -DMINOR_VERSION=${MINOR_VERSION} I3_CPPFLAGS += -DPATCH_VERSION=${PATCH_VERSION} I3_CPPFLAGS += -DSYSCONFDIR=\"${SYSCONFDIR}\" I3_CPPFLAGS += -DI3__FILE__=FILE

Libraries flags

ifeq ($(shell which pkg-config 2>/dev/null 1>/dev/null || echo 1),1) $(error "pkg-config was not found") endif

An easier way to get CFLAGS and LDFLAGS falling back in case there's

no pkg-config support for certain libraries.

NOTE that you must not use a blank after comma when calling this:

$(call ldflags_for_lib name, fallback) # bad

$(call ldflags_for_lib name,fallback) # good

Otherwise, the compiler will get -l foo instead of -lfoo

We redirect stderr to /dev/null because pkg-config prints an error if support

for gnome-config was enabled but gnome-config is not actually installed.

cflags_for_lib = $(shell pkg-config --silence-errors --cflags $(1) 2>/dev/null) ldflags_for_lib = $(shell pkg-config --exists 2>/dev/null $(1) && pkg-config --libs $(1) 2>/dev/null || echo -l$(2))
