Reported by Andre da Costa Barros. https://savannah.gnu.org/patch/?9716 * examples/calc++/local.mk: We no longer generate position.hh and stack.hh. Leaving them here triggers their concurrent generation, which fails. (%C%_calc___CPPFLAGS): Fix the extracted headers in the source tree. * examples/mfcalc/local.mk (%C%_mfcalc_CPPFLAGS): Ditto.
This directory contains examples of Bison grammar files. Most of them come from the documentation, which should be installed together with Bison. The URLs are provided for convenience. * Examples in C ** rpcalc - Reverse Polish Notation Calculator The first example is that of a simple double-precision Reverse Polish Notation calculator (a calculator using postfix operators). This example provides a good starting point, since operator precedence is not an issue. Extracted from the documentation: "Reverse Polish Notation Calculator" https://www.gnu.org/software/bison/manual/html_node/RPN-Calc.html ** mfcalc - Multi-Function Calculator A more complete C example: a multi-function calculator. Extracted from the documentation: "Multi-Function Calculator: mfcalc". https://www.gnu.org/software/bison/manual/html_node/Multi_002dfunction-Calc.html * Examples in C++ ** c++ - A directory of simple C++ examples ** calc++ - A Complete C++ Example A fully featured C++ version of the canonical example for parsers: a calculator. Also uses Flex for the scanner. Extracted from the documentation: "A Complete C++ Example". https://www.gnu.org/software/bison/manual/html_node/A-Complete-C_002b_002b-Example.html ----- Local Variables: mode: outline fill-column: 76 ispell-dictionary: "american" End: Copyright (C) 2018 Free Software Foundation, Inc.
