If you have multiple PHP versions installed, you may be able to specify for which installation you'd like to build by using the --with-php-config option during configuration.
--with-php-config=[Insert path to proper php-config here]
For example (my case):
./configure --with-php-config=/usr/local/php5/bin/php-config5
PHP - Manual: 用 phpize 编译共享 PECL 扩展库
2024-12-20
用 phpize 编译共享 PECL 扩展库
有时候不能用 pecl
安装命令。这可能是因为在防火墙后面，或者是因为想要安装的扩展库还没有
PECL 兼容的包，例如 Git 中尚未发布的扩展库。如果要编译这种扩展库，可以用更底层的编译工具来手工进行编译。
phpize 命令是用来准备 PHP
扩展库的编译环境的。下面例子中，扩展库的源程序位于
extname 目录中：
$ cd extname $ phpize $ ./configure $ make # make install
成功的安装将创建 extname.so 并放置于
PHP 的扩展库目录中。需要调整
php.ini，加入 extension=extname.so
这一行之后才能使用此扩展库。
如果系统中没有 phpize 命令并且使用了预编译的包（例如
RPM），那要安装 PHP 包相应的开发版本，此版本通常包含了
phpize 命令以及相应的用于编译 PHP 及其扩展库的头文件。
使用 phpize --help 命令可以显示此命令用法。

When compiling an extension for a stack which is 64 bits (for example) and your compiler is configured to compile in 32 bits, you can manually compile your extensions using C flags before your configure.
Example: my system compiler is 32 bits and my stack is 64 bits. To compile my xdebug:
# phpize
# CFLAGS=-m64 CPPFLAGS=-m64 CCASFLAGS=-m64 ./configure --enable-xdebug
# gmake
# file modules/xdebug.so
modules/xdebug.so: ELF 64-bit LSB dynamic lib AMD64 Version 1, dynamically linked, not stripped, no debugging information available

When you have multiple installations of PHP, running phpize from a specific installation will not force the module to be compiled with that installation's include files.
In my case, I had a standard PHP distribution installed, and am evaluating Zend Core / Zend Platform, which installed it's own Apache & PHP in a /usr/local/Zend/.. install path. It was missing the json.so module, so I had to compile my own.
Running Zend Core's phpize, the output indicates that configuration for that module will occur. But when running ./configure, the standard installation's include files are used. The result json.so being compiled against the wrong PHP would not load when Zend Core's php initializes.
The only way I could see to correct the situation was to temporarily change the standard PHP include path to point to the Zend Core's include files. In my case, I made a backup copy of /usr/include/php5 and did a "ln -s /usr/local/Zend/Core/include/php/ /usr/include/php5".

If you failed to run phpize command, then you should install php-devel package. Command line to install the php-devel package using yum is: yum install php-devel.
If you failed to compile the PECL extension, then you should install gcc package. Command line to install the gcc package using yum is: yum install gcc.

In some situations (e.g. on a cPanel server), the built extension will not be placed into the correct extensions directory by the make install process. Use your phpinfo() output to determine what the correct extension_dir path is and move the generated .so file into that directory. The extension=extname.so line in php.ini will then find the extension file correctly.
