Errors upon installation attempt

[bws428]

While running install_hplp.sh I'm getting 3 errors like the following. Any ideas?

test_hpcalcs.c:104:13: error: format string is not a string literal [-Werror,-Wformat-nonliteral]
    vprintf(format, args);

I got the error of 'unexpected token' for the token $HIDAPI in line 15436 in ./configure, although I have the latest version of libhidapi installed. What should I do to help the script run and install successfully?
