mac下安装php zookeeper扩展

安装步骤

php-zookeeper依赖libzookeeper，所以需要先安装libzookeeper

安装libzookeeper

cd /usr/local/src/

wget http://mirror.bit.edu.cn/apache/zookeeper/stable/zookeeper-3.4.12.tar.gz

tar -xf zookeeper-3.4.12.tar.gz

cd zookeeper-3.4.12/src/c

./configure -prefix=/usr/local/zookeeper/zookeeper-3.4.12/

make && make install

安装php zookeeper扩展

cd /usr/local/src/

wget https://pecl.php.net/get/zookeeper-0.5.0.tgz

tar zxvf zookeeper-0.5.0.tgz

cd zookeeper-0.5.0

phpize

./configure –with-php-config=/usr/local/php/bin/php-config  –with-libzookeeper-dir=/usr/local/zookeeper/zookeeper-3.4.12/

make && make install

修改php.ini，新增extension=zookeeper.so，然后重启php

vim /usr/local/etc/php/7.0/php.ini

; Directory in which the loadable extensions (modules) reside.
; http://php.net/extension-dir
extension_dir = "/usr/local/lib/php/pecl/20151012"
; On windows:
; extension_dir = "ext"

extension=zookeeper.so

遇到的问题

无论是安装libzookeeper还是安装php zookeeper扩展，在执行make && make install命令时会出现类似下面错误。网上查找了很大资料，都没这方面的解决方案，貌似只有在mac下才会有这样的问题。

解决方法

分析上面问题，基本是变量和一些string函数没有被显示声明。解决方法就是将没有定义的变量注释掉，将没有显示声明的函数补上。

重写/usr/local/include/string.h 文件如下，可以直接拷贝使用。然后重新执行make && make install，就可以了。
