# This script generates PHP lexer and parser files required to build PHP. The
|
|
# generated files are ignored in the Git repository and packaged during the PHP
|
|
# release process into the release installation archive download. This way the
|
|
# bison and re2c dependencies are not required to build PHP when downloading
|
|
# release archive.
|
|
#
|
|
# Usage: genfiles
|
|
#
|
|
# Environment:
|
|
# The following environment variables can override default generators paths.
|
|
#
|
|
# YACC Parser generator program, default bison
|
|
# RE2C Lexer generator program, default re2c
|
|
# SED Path to sed program, default sed
|
|
# MAKE Path to make program, default make
|
|
#
|
|
# For example:
|
|
# YACC=/path/to/bison ./genfiles
