Hmm, did you install a libc-client-*devel* package? A libc-client package is not sufficient to compile the extension. > I copied the link that you referenced and it is identical to the config.m4 file > in the PHP 7.3.0 distribution that I downloaded.

My point is (that I think) that configure does not properly check whether the necessary stuff is installed, and may yield a strange error message otherwise (“error: utf8_mime2text() has new signature, but U8T_CANONICAL is missing.”), instead of clearly stating that required headers or the actual library are missing. If I'm right, this would be a bug (in my opinion), and should be fixed. -- Christoph M. Becker
