Can you share the output of

  pkg-config fuse --cflags --libs

i.e. the command embedded in your call to GCC?

For the link error I suspect that

  (1) You do not have package libfuse-dev installed (do you?) and

  (2) `pkg-config fuse --cflags --libs` evaluates to an empty
      string just like

        `pkg-config INVALID_WHATEVER --cflags --libs`

      does.

Does that help?

Best,
