Ah. It's even simpler to reproduce: define TEST_MACRO endef $(call TEST_MACRO) (note that's two blank lines in the define) It's not whitespace per se, it's the newline. Just using spaces alone won't cause a problem. This probably SHOULD be considered a bug in make; it should be able to ignore blank lines in this context just like whitespace. > You can resolve this problem by wrapping the foreach in a $(strip): > > > > > $(strip $(foreach ...)) Yes, and also you can just write: TEST_MACRO = $(eval a=a) $(eval b=b) (you don't need define/endef for this) which also ensures there are no newlines in the content of TEST_MACRO. _______________________________________________ Help-make mailing list Help-make@gnu.org https://lists.gnu.org/mailman/listinfo/help-make
