Windows下编译Mediapipe,C++版本

参考教程

1、Mediapipe - Windows10 编译Mediapipe C++版本保姆级教程_HW140701的博客-CSDN博客_mediapipe win10

2、Windows下编译C++ MediaPipe_木火火ZERO的博客-CSDN博客_windows 下编译c++

先是按照教程1进行编译hello_world，

VS2017社区版、opencv4.4.0(编译hello_world时没用到opencv，在编译hello_world时没出错误)、

bazel5.2.0

出现了很多LINK2005的错误，然后参考教程2，换成了VS2019社区版，又出现了下面的错误

错误信息：

来回切换VS版本、python版本，还是出现同样的问题

然后搜索到下面几个网页

用户对问题“升级Visual Studio后Bazel不再工作”的回答 - 问答 - 腾讯云开发者社区-腾讯云

Bazel is not working with visual studio 2019 · Issue #8589 · bazelbuild/bazel · GitHub

Windows: Add BAZEL_VC_FULL_VERSION for windows cc configuration · bazelbuild/bazel@e5b7bd6 · GitHub

我想到可能是bazel变量设置的问题，

我想是不是把，BAZEL_WINSDK_FULL_VERSION的值设置的高了，把这个值降低一点

我改成了10.0.17763.0，再次编译，成功编译了hello_world

我想原来是没有仔细看教程2的说明，

 在系统变量里面，我写的BAZEL_WINSDK_FULL_VERSION的值是10.0.19041.685，才导致了这个问题的出现，应该是10.0.19041.0

------------------------------------------------------------------------------------------------------------------

然后接着编译hand_tracking，错误，提示opencv3.4.10，然后把opencv改成3.4.10，workspace里面设置好路径，编译成功

hand_tracking

bazel build -c opt --define MEDIAPIPE_DISABLE_GPU=1 --action_env PYTHON_BIN_PATH="D:\\software\\major\\anaconda3\\python.exe" mediapipe/examples/desktop/hand_tracking:hand_tracking_cpu

再补一篇博客，这篇博客对在Ubuntu下编译mediapipe会有帮助
