It works only in implicit rules (or with GNU Make, but not with Solaris Make). Reported by Bruno Haible. http://lists.gnu.org/archive/html/bug-bison/2019-05/msg00009.html Diagnosed thanks to Kiyoshi Kanazawa. * examples/c/reccalc/local.mk, examples/d/local.mk, * examples/java/local.mk: Don't use $< in non implicit rules.
This directory contains examples of Bison grammar files, sorted per language.
Several of them come from the documentation, which should be installed together with Bison. The URLs are provided for convenience.
These examples come with a README and a Makefile. Not only can they be used to toy with Bison, they can also be starting points for your own grammars.
Please, be sure to read the C examples before looking at the other languages, as these examples are simpler.
