Just to be sure: did you do a complete "make clean all" cycle after
adjusting your configuration to enable gnutls, or after adding
--enable-utf8 to pcre?

Remember that Buildroot does not automatically rebuild packages: if you
enable gnutls, it will build gnutls, but it will not rebuild
glib-networking automatically.

If you can provide a simple test case (or maybe even an existing test
application for glib-networking) to reproduce the problem, it would
definitely be helpful. Same for the pcre / GRegex problem.

Best regards,

Thomas
