Tools don't work on rpi
The three tools have a line of code like,
while ((c = (char)getopt_long(argc, argv, "i:o:b:s:e:t:p:S:v:h:u", long_options, &option_index)) != -1)
-
getopt_long
returns (signed)int
-
char
is not guaranteed to be signed -
char
specifically isn't signed when compiling for rpi, for example (and in that case, the compiler complains that the!= -1
comparison can never fail. - the resulting executable will always print the help text and not actually do anything useful (super confusing
😀 )
I think that c
needs to be int
, not char
