Hi,
I must be missing something obvious... I'm using the shell function in
my Makefile with a recursive variable, however, it seems the command
in my shell function is only being evaluated once. I've tried this on
two different Linux distributions and get the same result; from
everything I read (even in the O'Reilly GNU Make book), this should
not be working this way. See below for an example:
--snip--
[marc.smith@catskill testing]$ cat Makefile
blah = $(shell date)
all:
@ echo $(blah)
@ sleep 10
@ echo $(blah)
--snip--
--snip--
[marc.smith@catskill testing]$ make

Mon Nov 14 09:51:14 EST 2011
--snip--
--snip--
[marc.smith@catskill testing]$ make -v

I gotta be missing something obvious -- right?
