Hi J.

Why do you disable debuginfo package:

%global debug_package %{nil}

?

It do not build without disabling the debuginfo
I have no idea why

The problem is something with empty *debuginfo*.list 8-(

Do a scratch-build without any obstacles for debuginfo files and post a link to the build log, please.

 - Use the source from the official website, not from "wdune", you can't just copy source tike that. Ask upstream to publish the source for 4.0.0 on their Sourceforge. Alternatively generate the source from the GIT repo but don't put on your server, instead just put the tar.gz as source: but add comment explaining how you generated the tar.gz

I would recommend:

# git clone https://git.code.sf.net/p/freewrl/git freewrl
# cd freewrl/freex3d/
# git archive --format tar.gz --prefix freewrl-4.0.0/ 36b721ca374d695c10af8137c943f27f12503014 > freewrl-4.0.0.tar.gz
Source: freewrl-4.0.0.tar.gz

 - Missing dist tag:

Release: 1%{?dist}

 - Why? This is surely not needed as build time:

BuildRequires: bitstream-vera-sans-fonts

 - This should be a Requires, not a BuildRequires:

Requires: desktop-file-utils

 - Why does it Requires Firefoy??

Requires: firefox

 - No:

%global debug_package %{nil}

You need to find why it's not working as expected. Mostly because you installed the library as 0644 instead of 0755: it needs to be executable to be stripped:

install -m 0755 -p ../freewrl-git/freex3d/src/lib/.libs/libFreeWRL.so.4.1.0 $RPM_BUILD_ROOT/%{_libexecdir}/libFreeWRL.so.4.1.0

Same, remove that junk:

echo > debugsourcefiles.list
echo >> debugsourcefiles.list

/usr/lib/rpm/find-debuginfo.sh

 - Are you sure there isn't a make install script? Yes there is.

 - No:

install -m 644 -p ../freewrl-git/freex3d/COPYING $RPM_BUILD_ROOT/%{_datadir}/freewrl
install -m 644 -p ../freewrl-git/freex3d/COPYING.LESSER $RPM_BUILD_ROOT/%{_datadir}/freewrl

 Don't install these licenses in datadir. Instead include them with %license in %files.

%license COPYING COPYING.LESSER

 - Glob the extension for man pages as the compression may change in the future:

%{_mandir}/man1/freewrl.1.*

 - Fix your changelog entry:

* Fri Jan 10 2020 J Scheurich <mufti11> - 4.0-1
- Initial packaging

 - the library should not go to libexecdir but libdir

 - Add docs:

%doc AUTHORS ChangeLog NEWS README TODO xAI-DESIGN.README


Reworked SPEC to work with more stuff (OpenCL, OpenGL), there are two bugs related to OpenCL that should be fixed upstream but I'm not touching Sourceforge with a ten foot pole.
