[osg-users] osgversion command fails with symbol lookup error on new clone of OpenSceneGraph 3.5.5 on Linux

[Robert Osfield]

Hi Curtis,

Curious, what Linux variant are you using?

FYI, I develop under Kubuntu 16.04 at present, so all the new Affinity
work written in Linux and I've run osgversion a number of times and
not seen any issues with missing linkage.  For dev work I don't
usually install the OSG though, instead setting my LD_LIBRARY_PATH to
pick up the OSG libs where they were built.  This means I don't have
to do a make install each time I modify the OSG codebase, I wouldn't
expect it to change behaviour w.r.t linkgage, but perhaps there is
some relationship.

I just checked the applications/osgversion/CMakeLists.txt and it
includes OpenThreads on the link line so it should work.

Is there any chance you've only install the updated OSG but not the
updated OpenThreads?

Robert.
