Re: [Bug-tar] Unable to build tar with PGI compilers

[+cc gnulib, the selinux-at code comes from there]

Thanks for the report!

Yes, for some reason ./configure thinks that tar should be built with
selinux support (so SELinux is working on your box?) and the build fails later.
The --without-selinux really could work-around this issue.

Copying the original report:

I'm not familiar with this compiler, thus the errors below are not
readable to me (maybe undefined symbol because of broken system header?).
Perhaps others might decode better ..  but I think that the best guess
would be to provide a patch which fixes gnulib's SELinux module for your
system/compiler.
