I have a crypto currency I've been working on. Its based off of the cryptonote deference code. When I run a build in Travis Ci it fails. I can't figure out what the error is referencing.
edit:removed personal detail................
It means that your version of G++ does not recognize the options -std=c11 and -Wmaybe-uninitialized- in other words, your compiler is too old. It must be quite ancient to not recognize -std=c11.
