Same error with OpenSuse 11.1

To install it manually on red-hat alike system you can do (as root):

wget 'http://pecl.php.net/get/crack'
cd crack-version
phpize
./configure
make
make install - this step will provide location of /path/to/crack.so
echo 'extension=/path/to/crack.so' > /etc/php.d/crack.ini
/etc/init.d/httpd restart

Please note that on 64bit linuxes it will give an warning that is described at bug #9710.

On my prev comment this:

wget 'http://pecl.php.net/get/crack'
cd crack-version

Is missing one command, it should look like this:

wget 'http://pecl.php.net/get/crack'
tar xzf crack-version
cd crack-version

It seems that crack is not compiling anymore under PHP 5.4 or higher because safe_mode has been removed.

http://es.php.net/manual/en/features.safe-mode.php


You get errors:

php-crack-0.4/crack-0.4/crack.c:99:7: error: 'struct _php_core_globals' has no member named 'safe_mode'

This bug has been fixed in SVN.

Snapshots of the sources are packaged every three hours; this change
will be in the next snapshot. You can grab the snapshot at

Thank you for the report, and for helping us make PHP better.

I've fixed the build with part of your patch. Thanks.

I'm also getting the issue on CentOS 6.5

Any idea on how to solve it on CentOS 6.5 64-bit?

I'm pasting the entire install, so maybe you can help figuring out and solving the issue:
