[Qemu-devel] one question on the makefile

[Wei Yang]

All,

I saw a makefile rule which confused.

This is in the tests/Makefile

.PHONY: $(patsubst %, check-qtest-%, $(QTEST_TARGETS))
$(patsubst %, check-qtest-%, $(QTEST_TARGETS)): check-qtest-%: $(check-qtest-y)
        $(call quiet-command,QTEST_QEMU_BINARY=$*-softmmu/qemu-system-$* \
                gtester $(GTESTER_OPTIONS) -m=$(SPEED) 
$(check-qtest-$*-y),"GTESTER $@")

I know the general idea is to create a rule for target such as
check-qtest-x86_64.

There are two colons, usually there is one colon in dependency.

And the result dependency is
check-qtest-x86_64: tests/fdc-test tests/rtc-test tests/cwd-test

It is expanded to the content of check-qtest-x86_64-y.

I searched the googl and makefile manual. Do not find a result.
Could someone give me a hint?


Thanks a lot.
