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?
Rich.
