php – Can't phpize or configure an extension in OS X 10.9 Mavericks

Posted by: admin April 23, 2020 Leave a comment


I am trying to build the memcached extension on OS X 10.9 Mavericks for use with the built in PHP 5.4, initially I tried pecl install memcached but that threw the following.

checking for zlib location... configure: error: memcached support requires ZLIB. Use --with-zlib-dir=<DIR> to specify the prefix where ZLIB headers and library are located
ERROR: `/private/tmp/pear/install/memcached/configure' failed

So I created a tmp directory and executed pecl download memcached, unzipped the code and cd’d to the appropriate directory.

Trying to phpize it returned the following:

grep: /usr/include/php/main/php.h: No such file or directory
grep: /usr/include/php/Zend/zend_modules.h: No such file or directory
grep: /usr/include/php/Zend/zend_extensions.h: No such file or directory
Configuring for:
PHP Api Version:        
Zend Module Api No:     
Zend Extension Api No:  

I had brew installed zlib a while ago and pointed ./configure at my installation.
./configure --with-zlib-dir=/usr/local/Cellar/zlib/1.2.8 I was greeted with the following error message:

checking for session includes... configure: error: Cannot find php_session.h

So now I’m wondering the best course of action here… /usr/include/ doesn’t exist at all… is this a Mavericks thing? I don’t remember having this problem in 10.8 at all.

I could try brew installing php-devel but I presume that isn’t going to be the right version of what I need? Any help would be greatly appreciated here


locate php_session.h reveals


should I just ln -s this to the expected location or is there some way to do this via XCode? I have the command line tools installed…

How to&Answers:

run xcode-select --install to install the XCode5 Command Line Tools, then sudo pecl install memcache. You should be good to go.


After install XCode5 Command Line Tools as afessler sugest (xcode-select –install) I couldn’t do the “sudo pecl install memcache” because pecl was missing.
I had to install PEAR and PECL following this guide: http://techtastico.com/post/como-instalar-pear-y-pecl-en-os-x-mavericks/.
Then all worked good. Thanks!


I had this problem and it was due to MAMP not having all the PHP sources.

I found this really helpful solution that explains how to download and configure them:

Note that the MAMP components doesn’t include the extras for any versions of PHP higher than php 5.4.10 but you can download the extras from http://php.net/releases.


As said above but not using xcode install
Try installing pecl manually:

  curl -O http://pear.php.net/go-pear.phar 
  sudo php -d detect_unicode=0 go-pear.phar 

and then:

 sudo pecl install memcache
