During each make run, the build system checks that any specified dependencies do actually exist, to prevent typos and other errors from fouling up correct dependency settings. However, it also causes make to trip up when new components have been added to the code, but not yet registered in the build system by configure. A manual configure call is required in this case.
The "config" target is designed precisely to reinitialize the build without having to manually call configure. Skip the dependency check when running the "config" target to allow automatic reconfiguration in such cases. --- So this has way too wordy a log message and the comment could also be improved. Plus, it's not exactly an epitome of beauty in the first place. But it works automatically without the need for setting environment variables. tests/Makefile | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/tests/Makefile b/tests/Makefile index 939490b..157d20c 100644 --- a/tests/Makefile +++ b/tests/Makefile @@ -20,7 +20,11 @@ tests/data/vsynth2.yuv: tests/rotozoom$(HOSTEXESUF) | tests/data tests/data/asynth% tests/data/vsynth%.yuv tests/vsynth%/00.pgm: TAG = GEN +# Do not check existence of config variables when reconfiguring to allow new +# config variables getting registered in the build system. +ifneq ($(MAKECMDGOALS),config) CHKCFG = $(if $($(1))$(!$(1)),$($(1)), $(error No such config: $(1))) +endif ALLYES = $(strip $(call XYES, $(1))) XYES = $(if $(strip $(1)), \ -- 1.7.9.5 _______________________________________________ libav-devel mailing list [email protected] https://lists.libav.org/mailman/listinfo/libav-devel
