Can anyone explain how to assign the value of $(a) in the following makefile?
This is a simplified version of what I am trying to do: I need to perform
filtering on the input $(1) so I cannot simply substitue $(1) for $(a) in
the following example.
# makefile
define macro
a:=$(1)
a-copy:=$(a)
a-reference=$(a)
$(eval a-copy-eval:=$(a))
$(eval a-reference-eval=$(a))
foo:
@echo 'a=$$(a)'
@echo 'a-copy=$$(a-copy)'
@echo 'a-reference=$$(a-reference)'
@echo 'a-copy-eval=$$(a-copy-eval)'
@echo 'a-reference-eval=$$(a-reference-eval)'
endef # XMake_outfileRule
$(eval $(call macro,hello))
# eof
