Can't compile image after upgrading to OS X Yosemite

Actually, X11 is not erased but moved to /opt/X11.

So, the simplest solution would probably be to manually add the symbolic link from /usr/X11 to /opt/X11:

sudo ln -s /opt/X11 /usr/X11

Fixed after installing the latest XQuartz: http://xquartz.macosforge.org/landing/

The problem seems to be related to the fact that X11 was erased during the upgrade.

Same problem after installing OSX Catalina ...

But now, you need to make a link like this:

sudo ln -s /opt/X11 /private/var/select/X11

(The link /usr/X11 points to /private/var/select/X11 and can't be modified.)
