php7 installation extension phpize does not generate configure file

I just installed php7 on Ubuntu and I am wondering what extensions are needed.
After that, you need to install the curl extension
Source code directory

<code># cd ext/curl
# phpize
//预计生成configure文件 但是不知道为什么没有生成 自然后面的命令就没有执行
#./configure --with-php-config=/usr/local/php/bin/php-config --with-curl=DIR</code>

Does phpize depend on anything?

The following is my php environment

<code># php -v
