When I try to compile the off-the-shelf fastHOG code, the compiler complains that it can&#8217;t find fltk\/run.h. According to Rahul Ashok&#8217;s tutorial about fastHOG, I need to install Fast Light Toolkit (FLTK) 2.0. The tutorial says that FLTK versions other than 2.0 do not work.

When I do make in the fltk-2.0 folder, I get errors like undefined reference to &#8216;FcInit&#8217;.
