opencv - 在 Raspberry Pi 2 上使用 TBB 编译 OpenCV 3

Question

有没有人在 pi 2 上的最新 rasperian 上成功安装了启用了 TBB 的 opencv 3.0.0？

我按照这里的指南
https://www.raspberrypi.org/forums/view ... v3#p761255

我所做的唯一区别是通过 cmake 启用 TBB ...添加了 BUILD 和 WITH TBB 选项，如图所示。
cmake -D CMAKE_BUILD_TYPE=RELEASE -D BUILD_TBB=ON -D WITH_TBB=ON -D CMAKE_INSTALL_PREFIX=$(python3 -c "import sys; print(sys.prefix)") -D PYTHON_EXECUTABLE=$(which python3) ..

据我所知，我已修补当前所有依赖项。
cmake 报告它将安装和旧版本的 tbb ......

-- Use TBB: YES (ver 4.1 interface 6102)

制作过程因我不完全理解的链接问题而失败，

我尝试过的事情...

我认为更新版本的 TBB 可能会有所帮助......所以在如上所示失败后，我破解了 opencv 安装程序并进行了更改
将 TBB 加载到最新版本……不开心……同样的问题。

试图让它完成我发现我可以更新 opencv/apps 文件夹中的 cmakelists.txt 而不安装注释应用程序..
还是失败了。但在不同的应用程序.. traincascade... 删除它.. 相同... 从 CmakeLists.txt 中删除目录中的最后一个应用程序
它成功了。但是，当尝试链接我的 c 应用程序时，它会提示 imgproc 上 Unresolved 引用:|

运行 ccmake ../并关闭构建测试和其他附加功能......不高兴。

感谢我能提供的任何帮助.. 如果可以的话，希望 tbb 为我的 pi 使用四个内核!
