How to write multiple conditions in Makefile.am with “else if”
ptomato’s code can also be written in a cleaner manner like: ifeq ($(TARGET_CPU),x86) TARGET_CPU_IS_X86 := 1 else ifeq ($(TARGET_CPU),x86_64) TARGET_CPU_IS_X86 := 1 else TARGET_CPU_IS_X86 := 0 endif This doesn’t answer OP’s question but as it’s the top result on google, I’m adding it here in case it’s useful to anyone else.
