Although Paul has already answered for you, I'll show you how to find out
in the general case whether a version of make has a function in it or not:
use the --warn-undefined-variables flag, because if make doesn't recognise a
$(function) name, it'll assume you just mean an ordinary variable:
[EMAIL PROTECTED] make]$ cat makefile
# This function does exist
$(info Hello, Make)
# This function does not exist
$(unfo Goodbye, Make)
all:
[EMAIL PROTECTED] make]$ make
Hello, Make
make: `all' is up to date.
[EMAIL PROTECTED] make]$ make --warn-undefined-variables
Hello, Make
makefile:6: warning: undefined variable `unfo Goodbye, Make'
make: `all' is up to date.
[EMAIL PROTECTED] make]$
cheers,
DaveK
