我已经编译好了我已经为 natty 编译了 libfreenect 并且现在我正尝试安装 kinect 鼠标：https://github.com/Ooblik/Kinect-Mouse/
但是当我输入时make我收到一个错误......
这是终端：
eric@eric-desktop:~$ cd /home/eric/kinect_mouse
eric@eric-desktop:~/kinect_mouse$ mkdir build
eric@eric-desktop:~/kinect_mouse$ cd build
eric@eric-desktop:~/kinect_mouse/build$ cmake ..

答案1
该错误表示缺少库。grep -rn freenect_set_video_format .在包含以下内容的目录中执行操作时libfreenect，发现fakenect/fakenect.c包含所需的功能。读取fakenect/自述文件明确指出您在构建时需要链接到该库kinect_mouse。
因此，编辑kinect_mouse/CMakeLists.txt并link_directories(/usr/local/lib64/fakenect)输入：
cmake_minimum_required(VERSION 2.8)
link_directories(/usr/local/lib64/fakenect)
add_executable(kmouse kinect_mouse.c)
清除您的构建目录并重新构建。
