sudo pecl install apc error on os x lion

Question

I tried installing APC with pecl on OS X Lion (sudo pecl install apc) and it complained about a missing pcre.h file:

In file included from /private/tmp/pear/temp/APC/apc.c:44:
/usr/include/php/ext/pcre/php_pcre.h:29:10: fatal error: 'pcre.h' file not found
#include "pcre.h"

So I used MacPorts to install the pcre package (sudo port install pcre) but it still complains. How can I fix this?

Answer 1

"brew install pcre" worked for me.

Answer 2

I think this is because MacPorts installs the header files in a different location from where pecl expects them.

To fix this error, I symlinked pcre.h to /usr/include:

sudo ln -s /opt/local/include/pcre.h /usr/include/

When running sudo pecl install apc it compiled just fine.
