Hi,
I've had some problems on Debian Lenny with gcc 4.3 and optimisations. I
faintly remember an unexplained osgdem segfault as well. I'm not sure
what version of gcc you have installed, but try with another version or
other optim settings.

Hi Ben,
I'm afraid there is waaaay too little info about your setup to provide
any real guidance. VPB should just compile against an installed OSG
without need for configuration.
You don't mention which VPB or OSG version your are using, you also
make no mention of the platform or compilers. All this is important
to understanding what might go wrong and how to fix it.
Sorry for the lack of information. The OSG version is 2.2 and the VPB
version is 0.9.1. I am running a Ubuntu Linux 8.04 64bit on an Intel
platform, if this is also relevant.
The osg installation is straight from the Ubuntu package repository
(binary install, as opposed to local rebuild).
For building the VPB I added an extra line to the CMakeLists.txt
SET(GDAL_INCLUDE_DIR /usr/include/gdal)
so osgdem can be compiled.
I followed the standard
./configure
make
sudo make install
Everything seemed to be ok. For some reason my OS does not put 64bit
libraries in /usr/local/lib64, where the VPB libraries are, so I
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib64
This stops the "cannot find shared object" error from the loader.
And on executing
osgdem
with no arguments, it simply quits with a segmentation fault error.
I also followed the VPB tutorial at
http://www.openscenegraph.org/projects/VirtualPlanetBuilder
and despite the extra argument inputs I have the same error. So I reckon
I must have configured VPB wrong somehow.
Is there anything I overlooked?
Regards
Ben
