Comment 1 Fedora Program Management 2021-04-29 16:27:05 UTC
This message is a reminder that Fedora 32 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora 32 on 2021-05-25.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained. At that time this bug will be closed as EOL if it remains open with a
Fedora 'version' of '32'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 32 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Comment 2 Jan Pazdziora 2021-05-04 09:02:06 UTC

Comment 6 Jan Pazdziora 2021-11-14 13:48:12 UTC
Issue is still present on Fedora 35:

# rpm -qf /usr/bin/gvpack
graphviz-2.48.0-3.fc35.x86_64
# gvpack
gvpack: error while loading shared libraries: libgvplugin_neato_layout.so.6: cannot open shared object file: No such file or directory

Is there some additional information needed to get this fixed?

Comment 7 Jaroslav Škarvada 2021-11-23 16:27:06 UTC
Upstream ticket:
https://gitlab.com/graphviz/graphviz/-/issues/1838

Comment 8 Jaroslav Škarvada 2021-11-23 17:55:50 UTC
The problem is that it's linking the neato lib dynamically and simultaneously loading it at runtime as a plugin. If it is plugin, it shouldn't be accessible to the linker.

I resolved it the dirty way and statically linked the neato bits to the gvpack. Upstream should restructure the code.
