First of all there's no need to send screenshots of your GUI, logs will suffice. Secondly submit a PR, if you can't you're gonna have to learn git one day or another. Lastly, I'm not too sure I understand the issue, the strlcpy.c file is used to determine at compile time whether strlcpy is found in the c library. It is normal that it returns and error if the strlcpy is missing, as long at it does not affect the compilation of the actual libzeromq build.
