What is the error in the configure script and how to fix it?

Question

bash

I'm trying to configure the package, but it keeps saying:

line 480: continue: only relevant for "for", "while", or "until" loops

Swears on this line: The script is complete. What should the line look like?
if [ -z $var ]; then continue; fi

Answer 1

break and continue are only used inside loops to control them. If you want to abort script execution when $var is not empty, then as an option
if ! [ -z $var ]; then return 1; fi
