You have to pass one or more files for it to open on the command line, e.g.
$PREFIX/../src/gtk+-3.24.10/examples/application3/exampleapp ~/foo.txt ~/bar.txt

Where did Makefile.example come from and why did you find it necessary to build it by hand? It should have 
been built along with everything else.
