Subject: | [Caml-list] pa_macro to substitute a constant? |
How can I use pa_macro to substitute in a constant into a program? A real example: Makefile ------------------------------------------------------------ PACKAGE = foo VERSION = 1.0.0 version.cmo: version.ml Makefile ocamlc -I +camlp4 -pp 'camlp4o pa_macro.cmo -DPACKAGE="$(PACKAGE)" -DVERSION="$(VERSION)"' $< -o $@ version.ml ---------------------------------------------------------- let package = PACKAGE let version = VERSION --------------------------------------------------------------------- Needless to say this example doesn't work, and looking at the thin documentation for pa_macro, I'm not even sure it's possible. Is it?
