From: Diego Biurrun <di...@biurrun.de>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. Also skip the dependency check when doing clean, distclean and fate-rsync. --- tests/Makefile | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/tests/Makefile b/tests/Makefile index 1b3f319..1aed4f6 100644 --- a/tests/Makefile +++ b/tests/Makefile @@ -20,7 +20,11 @@ tests/data/vsynth2.yuv: tests/rotozoom$(HOSTEXESUF) | tests/data tests/data/asynth% tests/data/vsynth%.yuv tests/vsynth%/00.pgm: TAG = GEN +# Do not check existence of config variables when reconfiguring to allow new +# config variables getting registered in the build system. +ifneq ($(filter clean config distclean fate-rsync, $(MAKECMDGOALS)), $(MAKECMDGOALS)) CHKCFG = $(if $($(1))$(!$(1)),$($(1)), $(error No such config: $(1))) +endif
Another less backwards way of writing this probably would be ifneq ($(filter-out clean config distclean fate-rsync, $(MAKECMDGOALS)), ) I can amend it to that if you prefer that version. // Martin
