What about doing it with an EVAL statement?
Like this:
---------------------------- Begin to_upper.py
---------------------------------
$ cat to_upper.py
#!/usr/bin/env python
import sys
def main():
sys.stdout.write(sys.argv[1].upper().strip()+"\n")
if __name__ == "__main__":
main()
------------------------------- Begin Makefile
-----------------------------------
$ cat Makefile
INPUT := "test string"
OUTPUT := "UNDEFINED"
test:
@echo OUTPUT is: [$(OUTPUT)]
$(eval OUTPUT := $(shell python to_upper.py $(INPUT)))
@echo OUTPUT is: [$(OUTPUT)]
--------------------------------Results of Execution
-----------------------------
$ make test
OUTPUT is: [UNDEFINED]
OUTPUT is: [TEST STRING]
