Currently on the development branch of Fedora (28), an upstream change of glibc is being pushed where the Sun RPC support is removed from our downstream glibc package in favor of the libtirpc library. More details [0].

As a result, when python is trying to build the nis extension, it will complain with:
fatal error: rpc/rpc.h: No such file or directory
#include <rpc/rpc.h>
          ^~~~~~~~~~~
compilation terminated.

[vstinner]

Do you know if installing libtirpc-devel does install required rpc/rpc.h / fixes the issue?

[stratakis]

Already tried. Unfortunately it doesn't.

[stratakis]

The header is located at /usr/include/tirpc/rpc/rpc.h

[vstinner]

The header is located at /usr/include/tirpc/rpc/rpc.h

configure.ac should be modified to detect tirpc is installed. If yes, setup.py should add /usr/include/tirpc/ to includes to build the "nis" module.

[tiran]

I modified setup.py to look for libtirpc. In case the library is detected, it's added as dependency and /usr/include/tirpc is included in search path.

[benjaminp]

I think this is a duplicate of bpo-32007.
