解决configure: WARNING: You will need re2c 0.13.4 or later

我在安装rabbitmq php扩展的时候发现

configure: WARNING: You will need re2c 0.13.4 or later if you want to regenerate PHP parsers.

于是百度找解决方法

wget https://sourceforge.net/projects/re2c/files/0.16/re2c-0.16.tar.gz
tar zxf re2c-0.16.tar.gz && cd re2c-0.16
./configure
make && make install
