Sorry for the delay in answering your questions; I was abroad without
the ability to update the git repository.

As a rule of thumb: The error is most certainly not in `ftview' but in
your code. It is *very* unlikely that `ftview' works for all formats
but GF...
Attached you can find small fixes to make output of the first `make'
call prettier, and to allow `make devel; make' actually work. I've
also attached the log output of `make devel'; as you can see there are
zillions of warnings that you still have to take care of – if I
remember correctly, I advised you to use `make devel; make' for
development, and it is not clear to me why you didn't follow this
advice... At least you should have analyzed what it does and transfer
the used compiler flags to your build environment.
After fixing those buglets I compiled the demo programs, and the call
ftview 20 cmr10.2602gf
crashed immediately. Running with valgrind gives

So you have to find out why this happens. Note that the problem
happens with *any* file not recognized by other drivers as a font.
For example, you can say
ftview 20 make.log
to trigger the bug...
If I remember correctly I also advised you to add calls to the various
`FT_TRACEX' macros, which both helps you and the user in debugging
issues. Now is the time to do that!
BTW, what simple program are you using to check whether the GF module
works? For example, have you adapted
https://www.freetype.org/freetype2/docs/tutorial/example1.c
to your needs? Please post it.
You should work hard to resolve those issues. Second evaluation is
coming soon...
