我正在尝试在 Ubuntu 16.04 LTS 环境中运行 CUDA 7.5 工具包，并且已经非常接近拥有全部功能。我可以运行 deviceQuerry （如下所示），但我无法运行某些示例（如下所示）（nbody）。
我在使用 libGLU.so 库和相关文件时遇到了问题，但我能够解决这些错误...但现在我无法解决下面列出的错误...
您知道可能存在什么问题以及我可以尝试如何修复它吗？

-fp64 (use double precision floating point values for simulation)
-hostmem (stores simulation data in host memory)
-benchmark (run benchmark to measure performance)
-numbodies=<N> (number of bodies (>= 1) to run in simulation)
-device=<d> (where d=0,1,2.... for the CUDA device to use)
-numdevices=<i> (where i=(number of CUDA devices > 0) to use for simulation)
-compare (compares simulation results running once on the default GPU and once on the CPU)
