In GNU Make, how do I convert a variable to lower case?

Question

This is a silly question, but.... with GNU Make:

VAR = MixedCaseText
LOWER_VAR = $(VAR,lc)

default:
        @echo $(VAR)
        @echo $(LOWER_VAR)
<         


        

Answer 1

I find this slightly cleaner...

$(shell tr '[:upper:]' '[:lower:]' <<< $(VAR))
