How can I see if my Emacs was built with xft support?

I've installed emacs using pacman on Arch linux. How can I see if 开发者_如何学编程it has xft support or not ?

This does it for me:

ldd `which emacs` | grep libXft

If it's built with libXft, you should get:

libXft.so.2 => /usr/lib/libXft.so.2 (0xb6df9000)

There are probably more elegant ways to get this information, but the buffer created by M-x report-emacs-bug contains information about the build options. Too lazy to go and check where it fetches this information. Just kill the *mail* buffer once you have gleaned the information you need.
