Hi Jan,
The only way you could have problems is if you rely on the OSG
libraries shipped by the distro, where you don't have control over how
it was compiled.
That is precisely what's going to happen. My

Actually the default version Qt 5.4 dynamically selects what it thinks is the

You can force it to use desktop OpenGL by calling
QCoreApplication::setAttribute(Qt::AA_UseDesktopOpenGL) on your app instance
before you call exec on it.

The biggest problem is the AMD Intel's OpenGL driver is still have many
bugs,i prey let ATI dis appear ever day,one day ATI doesn't exist in the

Hi,
You just have to build OSG twice using each version of Qt in turn. OSG
respects the DESIRED_QT_VERSION already.
cmake -DDESIRED_QT_VERSION=5 - use Qt 5.x
cmake -DDESIRED_QT_VERSION=4 - use the Qt 4.x series
Yes, but then you won't be able to install those two OSG versions at the

I have just tagged the OpenSceneGraph-3.3.8 developer release. Focus for

Hi Robert,
that's certainly an option, and it seems like the option that would place the
least burden on developers. I like the idea.
Counting the lines of code in osgQt we have just under 2000 lines in
implementation files, having that much code in headers shouldn't be too much of
a problem.

Compiles and runs fine on Windows 7 + Qt 5.4.1 + MingW 4.9.1

hi robert,
For example,i know a opengl engine,named C4 engine current URL is:
http://www.terathon.com/
This engine from it's birthday,many years before,i always test their
demos,and from the first days,found it's shadow use opengl shaders,so judged
this engine will encounter many many

Hi,
as a first step to rectify the problem I have introduced a version check within
osgQt (include/osgQt/Version) to store the Qt version that osgQt has been
compiled against. If there is a version mismatch, the build process will abort
with an #error rather than crashing at runtime later on.
