In Linux how to add a build step in Qt Creator that uses su privileges without getting the wrong password attempts on builds?

Question

My goal is to successfully link a folder to /opt/ directory- which needs to be run with sudo.

I have tried this:

 system(sudo ln -s $$OUT_PWD/xampp /         


        

Answer 1

After a lot of research:

ssh-askpass Sudo Password | sudo -S bash ./script

Worked like a charm, it asks for the password in a separate window/prompt box. I added it under custom build steps. The important thing is to let sudo know that it will expect a password input via -S option.

echo "password" | sudo -S bash ./script

Also works with bash scripts, however as you might think it is insecure storing the sudo password inside the script. It is said that read permissions should fix that issue.
