examples/Makefile: disable -O2 optimizations There is no much point in optimizing example code, and the -O2 flag is annoying when debugging. 2013-06-26 14:13:58 +00:00			`CFLAGS += -Wall -g`
examples/Makefile: give priority to pkg-config flags In case CFLAGS/LDLIBS are already defined and conflicting with the pkg-config flags, give priority to the latter since they are used to detect compilation flags. This should fix for example the case where there are many different instances of a library, CFLAGS=-I/foo/include and pkg-config cflags say -I/bar/include. 2012-08-24 14:49:04 +00:00			`CFLAGS := $(shell pkg-config --cflags $(FFMPEG_LIBS)) $(CFLAGS)`
