The php version does not correspond to the phpize and php-config used during compilation, and absolute paths need to be used for compilation. Use absolute paths to execute PHP.

/usr/local/php-5.4.17/bin/phpize
./configure --with-php-config=/usr/local/php-5.4.17/bin/php-config
/usr/local/php-5.4.17/bin/php server.php

Missing mysql header file

php_mysqli_structs.h:64:23: fatal error: my_global.h: No such file or directory

The header file of mysqlclient is not found, you need to install mysqlclient-dev

It is recommended to compile php yourself. Do not use the PHP version that comes with the Linux package management system

Missing pcre.h header file

fatal error: pcre.h: No such file or directory

The reason is that pcre is missing and libpcre needs to be installed

Cannot find autoconf

The phpize command requires the autoconf tool, please install it first.

make install failed

make install requires root permissions. If you are not logged in as the root user, please use sudo or su and then install.
