Thanks. I came up with something similar, but I think your recipe is a bit
more elegant ...

Somewhat OT - A Makefile Question
Not strictly FBSD, but ... Within a makefile, I need to assign the name of a program as in: FOO = bar. The problem is that 'bar' may also be know as, say, bar.sh. Worse still both bar and bar.sh can exist with one linked to the other. Is there a simple way to determine which form bar or bar.sh on on a given system *at the time the make is run*? If both exist, I will pick one arbitrarily, I just don't want the detection mechanism to fail when this is the case. For example I don't think this works when both are there: FOO = $(shell `which bar bar.sh) Thanks, -- Tim Daneliuk tun...@tundraware.com PGP Key: http://www.tundraware.com/PGP/ ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
