In PHP dynamic compilation, cannot find Autoconf is used to dynamically compile the memcache extension library of PHP.

In PHP dynamic compilation, cannot find Autoconf appears.

After installing PHP, you want to dynamically compile the memcache extension library of PHP.

CD memcache-2.2.5/
/Usr/local/webserver/PHP/bin/phpize
./Configure -- With-PHP-Config =/usr/local/webserver/PHP/bin/PHP-config

However, an error occurs when/usr/local/webserver/PHP/bin/phpize is executed:

Processing ing: Php api version: 20041225 Zend module api no: 20060613 Zend extension api no: 220060519 Cannot findAutoconf. Please check your Autoconf installation and $ Php_autoconfEnvironment variable is set correctly and then rerun this script.

I searched the internet and found that there were a lot of people asking this question. I picked it up for a while:

# Wget http://ftp.gnu.org/gnu/m4/m4-1.4.9.tar.gz
# Tar-zvxf m4-1.4.9.tar.gz
# Cd m4-1.4.9/
#./Configure & make install
# CD ../
# Wget http://ftp.gnu.org/gnu/autoconf/autoconf-2.62.tar.gz
