Hello, %{_docdir} is a very strange macro , why rpm -E doesn't know what is %{_docdir} but %{_defaultdocdir} knows ?

rpm -E "%{_docdir}"
%{_docdir}
rpm -E "%{_defaultdocdir}"
/usr/share/doc 

So should I use %{_defaultdocdir} instead %{_docdir} ?

Please use %{_docdir} . Also, to make your .spec file support older platforms check whether./configure or `make install` support a similar parameter and pass %{_docdir} to them.

and how %{_docdir} is set ?

grep for it in textual files of rpm and rpm-build packages. If not found, download source files of rpm and look in C files.

Another matter is this wiki page : https://fedoraproject.org/wiki/Packaging_tricks#Installing_documentation:_2_... is not in line with https://fedoraproject.org/wiki/Changes/UnversionedDocdirs , should I update wiki page and change %{name}-%{version} with just %{name} ?

For example, in RHEL 6.8 the dirs are versioned. Please find in which version of rpmbuild that was changed and mention that in wiki.

Also https://fedoraproject.org/wiki/How_to_create_an_RPM_package "rm -rf $RPM_BUILD_ROOT" should be cleaned ?
