If you tried to install the APC extension on the MAC and got the following error:

pecl mac error: ‘apc_regex’ has no member named ‘nreg’

The problem is that APC depends on the PCRE library and we need to install it before compiling APC. Here is how to fix it!

• Open a TERMINAL session,  type :  mkdir  temp
• Head up to this page and download a PCRE library (try to use the latest one). I took pcre-8.12.zip, put the file inside the temp directory
• uncompress the PCRE archive via Finder (or any other way)


cd  pcre-x.xx replace x with the version number (example: cd  pcre-8.12)
./configure
make
sudo make install


• now download the latest APC release (link here)
• uncompress the APC archive via finder  (or terminal by typing    tar zxf  APC-X-XX  replace X with archive name and version number )
• type

cd ~/temp/APC-3.1.9    (change the version number if you're using something different)
phpize
./configure
make
sudo make install

you should see something similar to this when it’s done compiling

Installing shared extensions:     /usr/lib/php/extensions/no-debug-non-zts-20090626/
Installing header files:          /usr/include/php/

Modify your php.ini file to have the extension loaded at php startup

• Open /private/etc/php.ini   (in Finder, select GO menu, select GO TO FOLDER and type /private/etc)
• add this line in the Dynamic extensions area

extension=/usr/lib/php/extensions/no-debug-non-zts-20090626/apc.so


Restart the web server (reboot your machine if your lazy, or go into the System preferences, click on Sharing, un-select Web sharing , wait a few seconds and select it again )

You’re done, congrats!

Note:

There is a bug in version APC 3.1.9 

if you get error

Fatal error: Unknown: apc_fcntl_unlock failed: in Unknown on line 0

Relax! just modify the file apc_lock.h inside the APC folder you created. Edit the following line around lines 155-160

Find the following:

# define apc_lck_rdunlock(a) apc_fcntl_unlock(&a TSRMLS_CC)

Replace by the following

# define apc_lck_rdunlock(a) apc_fcntl_unlock(a TSRMLS_CC)

Recompile APC by doing:

cd ~/temp/APC-x-xx (replace X with version number) make clean phpize ./configure make sudo make install

And restart your web server! Too easy !  enjoy!

You may have noticed problems when trying to save/write/create/delete stuff on a SMB share after updating your Mac to update 10.6.3. The quick turn around is to edit the smb.conf file (usually find in /etc/samba/smb.conf) and add this line in the [GLOBAL] section:

unix extensions = no

restart samba and it will work again!

to restart SAMBA: /etc/init.d/samba restart
