PECL install fails / how to compile manually

When attempting to compile using PECL install, you will likely get an error stating:

checking whether the C compiler works… configure: error: cannot run C compiled programs.

This is due to the environment CentOS and Redhat flavors have for the /tmp directory. Rather than remounting /tmp without exec, you can compile the module manually on the user account. In this example, I’m compiling and installing the APC module. NOTE: ensure you are doing this ON the user’s account and not as root unless you want the module installed server wide.

cd ~
mkdir setups
cd setups
wget http://pecl.php.net/get/APC-3.1.2.tgz
tar -xvf APC-3.1.2.tgz
cd APC-3.1.2
phpize && ./configure –with-apxs && make

This will compile the module successfully, without the need to write or execute compiled programs in /tmp. Now simply add the extension to php.ini and ensure it loads in phpinfo().

You’re done.
