PHP 7 installation extension phpize does not generate the configure file

I just installed php7 in ubuntu. I want to add more extensions. After installing the curl extension source code directory {code...} is phpize dependent on anything? The following is my php environment {code...} just installed php7 in ubuntu. I want to add more extensions.
Complete the curl extension
Source code directory

# Cd ext/curl # phpize // The configure file is expected to be generated, but I don't know why the subsequent commands are not executed without being generated #. /configure -- with-php-config =/usr/local/php/bin/php-config -- with-curl = DIR

What does phpize depend on?

Below is my php environment
