The prerequisite does not seem to work correctly here. I can see that the symlinks are regenerated each time I run make. Even worse, during the second run, there is a ln -sf /home/thuth/devel/kvm-unit-tests/scripts scripts which generates a symlink in the source directory, since the "scripts" symlink already exists! I think you can not use automatic variables like $@ in the prerequisite list, can you? Maybe it would be better to create these symlinks in the configure script already? > -include */.*.d */*/.*.d > > + > +# We only need to link common scripts for out-of-src-tree builds > +ifneq ($(CURDIR), $(SRCDIR)) > +all: $(scripts-common) > +endif > + > all: $(shell git -C $(SRCDIR) rev-parse --verify --short=8 HEAD >build-head > 2>/dev/null) > > standalone: all > diff --git a/x86/Makefile.common b/x86/Makefile.common > index fbab82c..ef6e543 100644 > --- a/x86/Makefile.common > +++ b/x86/Makefile.common > @@ -54,8 +54,12 @@ tests-common += api/dirty-log > tests-common += api/dirty-log-perf > endif > > +scripts-common += $(TEST_DIR)/run > +scripts-common += $(TEST_DIR)/unittests.cfg > + > test_cases: $(tests-common) $(tests) > > + Cosmetic nit: Superfluous white space change. > $(TEST_DIR)/%.o: CFLAGS += -std=gnu99 -ffreestanding -I lib -I lib/x86 > > $(TEST_DIR)/realmode.elf: $(TEST_DIR)/realmode.o > Thomas _______________________________________________ kvmarm mailing list kvmarm@lists.cs.columbia.edu https://lists.cs.columbia.edu/mailman/listinfo/kvmarm
