Hi Dai
Thanks for your advice. Following the instruction, I still encountered some problems.
For the first step, I typed in "sudo apt-get install bison libglu1-mesa-dev libglew-dev libgl1-mesa-dev"
Then do "make libglutils.a libfb_glx.a"
After finishing these two steps, start compilation
and do "make". But some problems showed up
I don't know what's going on here. And hope it's not too much to ask you for help again.
