linux下编译php追加enable的方法
如果我们运行php时发现缺少某个库，在windows环境下很简单，找到.dll 对应的库文件，然后拷贝到 extension 目录下，然后在php.ini 里 去掉 前面的分号或者 追加一行 extension = XXXX.dll 即可。
linux环境下，可不是像windows环境下那么的简单。
下面我们已 sysvmsg 这个库文件的安装为例 来详细说明php的编译方法
收件进入php的原始文件
比如我是下载在这个路径下：
[root@localhost php-5.2.17]# cd /root/lnmp0.9-full/php-5.2.17
然后进入 ext 目录
/root/lnmp0.9-full/php-5.2.17/ext
接下来要进入我们需要增加的扩展的包 比如 这里是 sysvmsg
[root@localhost ext]# cd sysvmsg/
接下来我们需要在 sysvmsg 这个目录下创建 configure文件
[root@localhost sysvmsg]# /usr/local/php/bin/phpize （这里是我们php默认的已经安装的地址）
执行之后会提示以下信息：
[root@localhost sysvmsg]# /usr/local/php/bin/phpize
Configuring for:
PHP Api Version: 20041225
Zend Module Api No: 20060613
Zend Extension Api No: 220060519
此时我们可以看到 目录下会多出来很多文件

----------------------------------------------------------------------
Libraries have been installed in:
/root/lnmp0.9-full/php-5.2.17/ext/sysvmsg/modules
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR‘
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH‘ environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH‘ environment variable
during linking
- use the `-Wl,--rpath -Wl,LIBDIR‘ linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf‘
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
----------------------------------------------------------------------
Build complete.
Don‘t forget to run ‘make test‘.
[root@localhost sysvmsg]# make install

到这里我们就是安装完成了，会在extentsion目录下创建需要用到得.so 库文件
[root@localhost no-debug-non-zts-20060613]# ll

-rw-r--r-- 1 root root 45469 Feb 25 17:26 php.ini
然后我们需要修改php.ini 新增 .so 库文件
extension = "sysvmsg.so"
用wq 保存php.ini.
最后别忘了重新启动php
[root@localhost etc]# ps -ef | grep php
