I have the following code:
define build_proj_template
$(1): $(foreach bb,$(BB_$(patsubst build+%,%,$(1))),$(addsuffix
+$(bb),$(addprefix build+,$(patsubst build+%,%,$(1)))))
@echo "build_proj_template target : '$1' , dependencies : '$+'"
endef
## build+<proj> : build+<proj>+<bb>
$(foreach proj,$(PROJECTS),$(eval $(call build_proj_template,$(addprefix
build+,$(proj)))))
In a normal hard coded rule
build+ldb : build+ldb+dogs
@echo "build_proj_template target : '$1' , dependencies : '$+'"
Would print
build_proj_template target : 'build+ldb' , dependencies :
'build+ldb+dogs'
But what I get is:
build_proj_template target : 'build+ldb' , dependencies : ''
The $+ is getting lost in the define statement
