[issue32521] NIS module fails to build due to the removal of interfaces related to Sun RPC from glibc.

Charalampos Stratakis  added the comment:

Closing the issue as python2 is not receiving any more fixes and our downstream 
workaround is enough for it. Python3 is fine as well.

libnsl-devel requires libtirpc-devel here, so that isn't the issue.

I am not familiar with suse's build system webui to find the logs, but are 
those packages provided by the distribution?

[issue32521] NIS module fails to build due to the removal of interfaces related to Sun RPC from glibc.

[Matej Cepl]

Matej Cepl  added the comment:

> Matej is this about Python 2?

I am currently ONLY on building python 3.7.0, nothing else bothers me at the 
moment.

Let me summarize my findings, or what I think is the situation (of course, I 
could be completely wrong):

 * See 
https://build.opensuse.org/package/show/devel:languages:python:Factory/python3 
... Tumbleweed and Leap 15  (which all have libnsl) fail to be build with 
libnsl-devel installed. It seems to me that it somehow tries to build 
nismodule.c, but fails in configure (see above), so it doesn't end up well.

I think the problem is that the Python build system expects libnsl to be the 
one which is found in Solaris and so it looks for its API. Except, the Linux 
one is different and doesn't provide the same API. And from there, it goes all 
down to hell.

With Leap 42.3 (which has glibc-2.27-4.1, but no libnsl, so I guess NIS API is 
still inside of glibc; is it possible?), nis builds correctly and so it is 
included.

* Concerning Python 2. I don't see any problems with it. 
https://build.opensuse.org/package/show/devel:languages:python:Factory/python 
shows https://is.gd/sbwIf6 that glibc is the same glibc-2.27-4.1, 
libnsl-devel-1.2.0-2.1, ./configure still fails, but 
http://download.opensuse.org/repositories/devel:/languages:/python:/Factory/openSUSE_Tumbleweed/x86_64/python-base-2.7.15-112.1.x86_64.rpm
 still contains /usr/lib64/python2.7/lib-dynload/nis.so module.

OK, so I have no clue and it is all complete mess.

Charalampos Stratakis  added the comment:

Matej is this about Python 2? Because the solution didn't actually work for 
Python 2 and on Fedora we had to implement a workaround [0]. Unfortunately 
there weren't enough free cycles so far to investigate further.

Matej Cepl  added the comment:

It seems to be even more weird. Even with installed libnsl-devel 
(libnsl-devel-1.2.0-2.5.x86_64 on openSUSE/Tumbleweed) I get this in config.log:

checking for t_open in -lnsl... no

and truly, when grepping for t_open in /usr/include/rpc* I get nothing. When 
searching for t_open, it seems to be something from Solaris world.

It's not just the headers. The shared library is now /usr/lib64/nsl/libnsl.so.2

Unfortunately the yp_prot.h and ypclnt.h [0] headers have also moved to a 
different package.

Currently they reside at /usr/include/nsl/rpcsvc/*.h

> 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.
