In Fedora 26, the pkg-config implementation has been switched to pkgconf. This is a newer, actively-maintained implementation of pkg-config that offers more advanced support for
.pc files and provides a library interface for developers to integrate pkg-config processing into their applications.
More information about pkgconf can be found at pkgconf.org.
By default, core dumps from crashing programs are now stored by systemd-coredump, rather than created in the crashing process’s current working directory by ABRT. They may be extracted using the
coredumpctl tool. For example, simply run
coredumpctl gdb to view a backtrace for the most recent crash in gdb. For more information on this change, refer to the manpages
