Error during configure for v4.5 on Fedora

I encountered this error during my running ./configure on Fedora:
./configure: line 19741: syntax error near unexpected token <<<' ./configure: line 19741: <<<<<<< Local Changes’
What can I do now?
Thank you very much.

It looks like you modified your self either ./configure or ./configure.ac. Are you using the GitHub repo or a specific release version? In either case, I’d recommend you start the compilation from scratch, cf. the README.md.
