The escaping is absurd, but we need to escape for shell, sed, make, define

GIT_VERSION:="4.2 (2012-04-25, branch \\"release-4.2\\")" VERSION:=4.2

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))

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

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

Please test if -Wl,--as-needed works on your platform and send me a patch.

it is known not to work on Darwin (Mac OS X)

We need -idirafter instead of -I to prefer the system’s iconv over GNU libiconv

Fallback for libyajl 1 which did not include yajl_version.h. We need

YAJL_MAJOR from that file to decide which code path should be used.

Fedora changes - removed DEBUG and COVERAGE
