6.1. 运行Hello World

  1. 提取(extract) hello_world示例： 
    $ cd $OPAE_PLATFORM_ROOT/opencl

$ mkdir exm_opencl_hello_world_x64_linux

$ cd exm_opencl_hello_world_x64_linux

$ tar xf ../exm_opencl_hello_world_x64_linux.tgz
  2. 构建示例(build example)： 
    $ export ALTERAOCLSDKROOT=$INTELFPGAOCLSDKROOT

$ cd hello_world

$ make
  3. 将aocx复制到示例bin文件夹： 
    $ cp $OPAE_PLATFORM_ROOT/opencl/hello_world.aocx ./bin/
  4. 运行示例： 
    $ ./bin/host
    样例输出：
