POSIX Make supports conditionals, thanks to recursive macro expansion. And while POSIX doesn't yet support a macro construct to invoke and capture shell utilities, you can use both the GNU $(shell COMMAND) and Sun $(COMMAND:sh) syntax. All the BSDs and Solaris support the latter, and GNU Make the former. Both constructs are ignored with an empty string expansion where they're not supported, and no implementation supports both. To see what I'm talking about, see my proof of concept library that I've put together. https://github.com/wahern/autoguess/blob/config-guess/config... |
