Question

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

我在这里按照指南 https://www.raspberrypi.org/forums/view ... v3＃p761255

我唯一的区别是通过cmake启用TBB ...如图所示添加了BUILD和WITH TBB选项..

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) ..

我已修补当前，所有依赖项安装到我可以告诉.. cmake报告它将安装和旧版本的tbb ...

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

制作过程因链接问题而失败，我完全不了解

我尝试过的事情......

我认为更新版本的TBB可能会有所帮助...所以如上所示失败之后我攻击了opencv安装程序并更改了 TBB负载到最新版本......没有快乐..同样的问题。
尝试完成它我发现我可以更新opencv / apps文件夹中的cmakelists.txt而不安装注释应用程序。仍然失败了。但在另一个应用程序.. traincascade ...删除它..相同...从CmakeLists.txt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，它会抱怨imgproc：|
Ran ccmake ../并转向构建测试和其他额外内容......没有快乐。

感谢我的任何帮助..如果可以的话，我希望tbb能够为我的pi使用四核！

针对Raspberry Pi的预发布OpenCV（4.0.0）和Stable OpenCV（3.4.2）以及TBB（2018-Update 4）的最新预编译二进制文件（在Rpi版本2/3上进行了测试）带有Stretch的B / B +型）易于安装（.deb文件）

它是我从头开始构建的，您可以查看它以获取更多详细信息。
