thanks. menuconfig worked all the time, but it hurt my eyes :p
anyway I got it to work by simply copying all the error text and paste in the duckduckgo search. which handed me two results, of which the first link (if I remember correctly) was a website called something-something-bin. And there it was all along. I would like to take this opportunity to pardon that I didn't copy the error text and paste it in the duckduckgo search before opening the post. Also thank you for the guidance.
