mac下安裝php zookeeper擴展

安裝步驟

php-zookeeper依賴libzookeeper，因此須要先安裝libzookeeper

安裝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

安裝php zookeeper擴展

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，而後重啓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

遇到的問題

不管是安裝libzookeeper仍是安裝php zookeeper擴展，在執行make && make install命令時會出現相似下面錯誤。網上查找了很大資料，都沒這方面的解決方案，貌似只有在mac下才會有這樣的問題。

解決方法

分析上面問題，基本是變量和一些string函數沒有被顯示聲明。解決方法就是將沒有定義的變量註釋掉，將沒有顯示聲明的函數補上。

重寫/usr/local/include/string.h 文件以下，能夠直接拷貝使用。而後從新執行make && make install，就能夠了。
