Follows in my cheat sheet that I just put together for installing all the necessary bits on a clean install like this on - just install an Debian based OS then open up a win-term and copy and paste and go.
I am in awe of just how seamless packaging under Linux has become, it's simple, robust, reliable, quick and totally painless - exactly how computers should be. My heartfelt thanks to the ten of thousands of developers that have gone into making this dream system a reality ;-) Robert. -- # compile, build and version control sudo apt-get install cmake subversion g++ # OpenGL/X11 sudo apt-get install libx11-dev sudo apt-get install nvidia-glx-177-dev libglu-dev # image libs sudo apt-get install libpng-dev libjpeg-dev libtiff-dev # get true type font support sudo apt-get install libfreetype6-dev # geospatial imaging sudo libgdal-dev # check out OSG svn co http://www.openscenegraph.org/svn/osg/OpenSceneGraph/trunk OpenSceneGraph # compile the OSG cd OpenSceneGraph ./configure make -j 8 On 12/2/08, Robert Osfield <[EMAIL PROTECTED]> wrote: > Hi Ferdi, > > On 12/2/08, Ferdi Smit <[EMAIL PROTECTED]> wrote: >> I thought a hyper-threaded CPU was simply exposed as two distinct CPUs, >> i.e. an intel i7 would show up as 8 CPUs?
