This is the Makefile used in step 5 that will actually generate the font C file.
So, given your </code>NXFONTS_FONTID=2</code>, it needs to determine a prefix to use for auto-generated variable and function names and (again) the name of the autogenerated file to create (this must be the same name that was used in <code>nuttx/graphics/nxfonts/Make.defs</code>):
