In gcc 9.4.0, the
fread()function marked with the__wurmacro generates anunused-resultwarning when the result is not used, and due to the-Werrorflag in Makefile, it became a compilation error in facebooc (at least on my computer). I added an error handling mechanism that would help when there are errors reading the file.
