PHP Fatal error: Call to undefined function ImageTTFBBox

By , last updated April 20, 2015

This error happens when ImageTTFBBox is not available in the pool of PHP functions. To enable this method with PHP on Gentoo, you must build PHP with both GD and TrueType.

Required use flags in /etc/portage/package.use:

# /etc/portage/package.use
dev-lang/php gd truetype

Rebuild PHP with emerge.

emerge -av php

These are the packages that would be merged, in order:

Would you like to merge these packages? [Yes/No]

Press enter and wait a moment or two while PHP builds. After it’s done, restart your webserver. I use Apache

/etc/init.d/apache2 restart

Now your TrueType GD functions should be usable and present.
