Openscenegraph-dev hard links with Qt4. Binding for Qt5 desired.

Thank you for taking the time to report this bug and helping to make Ubuntu better. It seems that your bug report is not filed about a specific source package though, rather it is just filed against Ubuntu in general.

Hi,

Any news for this ?

The log¹ says "Dependency on Qt upgraded from version 4 to 5 (Closes: #875075).", but on 20.04 I can't find any dependency on Qt, 4 or 5:

- /usr/lib/x86_64-linux-gnu/pkgconfig/openscenegraph-osgQt.pc was removed between 18.04 & 20.04,
- `apt depends openscenegraph` shows "libqtcore4 (>= 4:4.5.3)" on 18.04 but nothing in 20.04.

¹: http://changelogs.ubuntu.com/changelogs/pool/universe/o/openscenegraph/openscenegraph_3.6.4+dfsg1-3build2/changelog

I guess the log only comes from this in Debian: https://salsa.debian.org/openscenegraph-team/openscenegraph-3.2/-/commit/3dbd461f69b744874d6868f4fae2247ecba217e9 ; but it might not have actually been applied here, right ?

Hi,

This report is of ages ago! I is not longer relevant to me, suggest to
close it and ignore it.

Regards, Rob

It's still relevant to me and my team. This package is the only thing preventing us to switch everything to Qt5, and honestly compiling anything for Qt4 is a pain…

I understood. 20.04 has OSG 3.6, and in 3.6, OSG moved osgQt in a separate source tree: http://www.openscenegraph.org/index.php/community/press-releases/223-openscenegraph-3-6-0-release

Then I think we can close this.
