在编译安装PHP时,提示告警信息:“configure: WARNING: You will need re2c 0.13.4 or later if you want to regenerate PHP parsers.”


这里它提示的是告警而非错误,但是为了验证它是否是致命的,所以必须了解re2c的作用

re2c的介绍:http://re2c.org/

re2c的下载:http://sourceforge.net/projects/re2c/files/re2c/

经确认,re2c可以提高性能,那就开始升级吧

下载最新的re2c版本,下载地址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

再次编译安装,发现告警信息消失
