Functions do accept % as argument, but strange things happen. Consider this
makefile (run with files Barticle and article in the directory)
art = article
scan = $(wildcard *$(1)) $(1)
article.xsl metadata.xsl: %.xsl: $(call scan,$(art))
@echo result $^
The result is
'result Barticle article'
It shows the scan function works as expected. However, if the call to scan is
replaced by $(call scan,%), (note % has the same value as $(art)) the result
becomes
'result article'.
It shows the wildcard function does not do its job properly. This becomes even
more clear when the definition of scan is replaced by 'scan = $(wildcard *$(1)
$(1))'. The result becomes
'result'
Replacing the scan-call back to its original $(call scan,$(art)), the result
becomes the (again) expected:
'result Barticle article'
This smells like a bug. Is there a workaround available, like copying the
contents of the variable?
