Description:
While updating my system I recieved this warning..
Warning: Could not load "/usr/lib/graphviz/libgvplugin_gs.so.6" - It was found, so perhaps one of its dependents was not. Try ldd.


Additional info:
* package version(s)
graphviz (5.0.1-1 -> 5.0.1-2)
ghostscript (9.56.1-1 -> 10.0.0-1)


* config and/or log files etc.
* link to upstream bug report, if any
https://gitlab.com/graphviz/graphviz/-/issues/2280

looks similar to  FS#50751

Not entirely. In this case, the file is found and the dependencies are not broken, unlike  FS#50751 .

LD_DEBUG shows the actual issue:

/usr/lib/graphviz/libgvplugin_gs.so.6: error: symbol lookup error: undefined symbol: gs_error_names (fatal)

GS now hides non-public API symbols by default:

Cfr. comment from arojas, this is due to the `ghostscript` PKGBUILD. After adding `--disable-hidden-visibility` to the configure step there and rebuilding GS the warning goes away.

We shouldn't revert new upstream behavior just for cosmetics.

Replacing the single use of `gs_error_names ()` in `src/graphviz-5.0.1/plugin/gs/gvloadimage_gs.c` solves this.

This is not just a cosmetic issue, the plugin doesn't load at all

Maybe keep this in testing till it is fixed in graphviz.

What's the recommendation for Arch users to temporarily fix this? E.g. what packages should be downgraded or instructions otherwise?
Comment by Doug Newgard (Scimmia) - Sunday, 25 September 2022, 15:56 GMT
cherio, if you actually need that plugin, rebuilding ghostscript as glitsj16 said would be a temporary workaround. If you don't need that plugin, ignore it.

cherio, here's a patch offering a temporary workaround if you need the affected plugin.

Please give 5.0.1-3 a try.
Comment by John Barks (Zod) - Monday, 26 September 2022, 12:11 GMT
Near as I can tell, this is fixed.
Comment by helle vaanzinn (glitsj16) - Monday, 26 September 2022, 12:27 GMT
For me 5.0.1-3 from testing fixed this. The warning is gone and the plugin is there. Thanks!
