PHP5.6.1

When compiling and installing PHP, Alert message: "Configure:WARNING:You would need re2c 0.13.4 or later if you want to regenerate PHP parsers."


Here it prompts for alarms rather than errors, but in order to verify that it is fatal, it is important to understand the role of RE2C

RE2C's introduction: http://re2c.org/

RE2C's Download: http://sourceforge.net/projects/re2c/files/re2c/

After confirming that RE2C can improve performance, start upgrading.

Download the latest re2c version, download the address Http://sourceforge.net/projects/re2c/files/re2c/0.13.7.5/re2c-0.13.7.5.tar.gz/download

# Tar XF re2c-0.13.7.5.tar.gz

# CD re2c-0.13.7.5

#./configure

#make && make Install

Compile the installation again and notice that the alarm information disappears
