A "$" by itself is assumed to be the beginning of a make variable. If you want a literal "$" to appear in your shell script you escape it by using "$$". Make will reduce the "$$" to "$" when it invokes the shell (GNU make will print out the command that it invokes just before invoking it). sh> I was therefore wondering if make might use it's own shell sh> interpreter. Definitely not. What a waste that would be, to reimplement the entire shell inside make! sh> You seem to be saying that make forwards to the shell Certainly. sh> (which one, the default shell of the user? Definitely not. If it did that, makefiles would break for every user who didn't have the same shell as that makefile author. It uses the contents of the make variable SHELL, which is set to /bin/sh unless overridden in the makefile (or command line). sh> Does it preprocess first to convert $$ to $?) Well, it handles escape characters, so yes certainly. Check the GNU make manual. sh> Ok, this is about as simple an example as I can create - should sh> only take a few seconds for anyone to compile and make: Hm. Your catch/throw example works fine on my system: from both the shell and make it exits with 0. I tried it with GNU make 3.79.1 on a Debian GNU/Linux system with GCC 3.3.1, glibc 2.3.2, and bash 2.05(b).0. -- ------------------------------------------------------------------------------- Paul D.
