Explaining makefile
- by Michael
xpi_built := $(build_dir)/$(install_rdf) \
$(build_dir)/$(chrome_manifest) \
$(chrome_jar_file) \
$(default_prefs)
xpi_built_no_dir := $(subst $(build_dir)/,,$(xpi_built))
$(xpi_file): $(build_dir) $(xpi_built)
@echo "Creating XPI file."
cd $(build_dir); $(ZIP) ../$(xpi_file) $(xpi_built_no_dir)
@echo "Creating XPI file. Done!"
$(build_dir)/%: %
cp -f $< $@
$(build_dir):
@if [ ! -x $(build_dir) ]; \
then \
mkdir $(build_dir); \
fi
can anyone explain me this makefile part? particularly interested in
$(build_dir)/%: % as well as $< and $@ directives
two labels $(build_dir) exists, I guess both are executed, but in which order?
