Hi,
this might be a radical solution, but you should be able to get
virtualbox with Ubuntu 8.04 LTS to build OSG 2.2 without problems and
hopefully do the convertions you need. Once you have it running you can
just archive the virtual machine for future use.

Hi Robert,
unfortunately i have to use older version of osg because currenty i am
fixing bugs of one our simulators which is developed in 2007and 2008.
we implemented this simulator in delta3D 1.4 which uses the older
version of osg.
i want to upgrade this system to the newer versions but i am afraid of
getting many errors.
there are many changes between versions like producer.
that's why i am trying to find some backward compatible solution...

HI Ufuk,
Is there a reason that you are using a version of the OSG so many
years out of date?
In very old versions of the OSG there was a problem under Windows with
osgconv attempting to create a graphics context due a crappy windows
issue of the MS compiler not pulling in symbols that it should have,
the only work around is to explicitly reference these symbols. Modern
versions of the OSG has this hack in them to workaround the Windows
problem.
Robert.
