Hi Ewe,
If you run cmake using the provided ./configure it'll automatically
set the release build.
W.r.t the optimization bug, I really don't want to start populating
the code with #ifdef compile_with_bug_version as we end with
unmangable code pretty quickly.
Testing -O2 would be interesting.
BTW, do you see the bug on any of the standard examples?
Robert.

Hello,
Back to front sorting in the transparent bin did not work in our
application on linux since quite a while.
Once we used CMake to build OpenSceneGraph, it worked correctly but our
application was three times slower than before.
It turned out, that I forgot to add -DCMAKE_BUILD_TYPE=RELEASE to the
cmake options and thus got a non optimized osg build.
With the optimized build I got decent framerates again but geometry
sorting did not work anymore.
It turned out to be CullVisitor.cpp in osgUtil which causes the bug to
appear if compiled with -O3 and disappear if compiled with -g.
The solution to the problem is not to inline the distance function.
inline CullVisitor::value_type distance(const osg::Vec3& coord,const
osg::Matrix& matrix)
we had this issue with
gcc-4.0.2
gcc-4.1.2
gcc-4.1.3
and other versions.
Robert, could you add a #ifndef __GNUC__ to the inline declaration or
convert it to a macro?
Uwe
