[参考译文] SK-AM62A-LP：基于 SK-AM62A-LP E3开发板运行 OpenCV 应用时出错

您好！

SDK 中安装的 OpenCV 对于此类示例应该就足够了。 我很想看到您有关该项目的 CMakeLists.txt 文件-您能否分享？

一个很好的例子是 edgeai-tidl-tools --见例子。 在 osrt_cpp 示例中、您可以看到使用 imwrite 的几个实例：

• https://github.com/TexasInstruments/edgeai-tidl-tools/blob/09347c5390eb95f80754dfbd7cbc7e98029254b9/examples/osrt_cpp/ort/onnx_main.cpp#L664 

这是交叉编译的一个选项、但此处不是必需的。 必要的头文件、库和编译器位于/usr 内的 SDK 中。 Yocto 用于创建 Linux 发行版、因此所有的软件包、工具、库、配置等都不是适合您的用例的工具。  

您是否使用 edgeai-gst-apps 作为此应用的起点？ 我看到目录结构与 APPS_CPP 的相似之处。 该工程(在/opt/edgeai-gst-apps/apps_cpp 下)构建时不会出现任何此类链接问题。

BR、

您好、我不知道如何使用 edgeai-gst-apps 作为应用程序的起点。 我可以在哪里参考它？
我之前测试的工程为 Hello world、可根据以下步骤在电路板上编译和执行：
1) mkdir 构建
2) CD 版本
3) cmake ..
4)制造
代码结构如下：

apps_cpp/文件夹中 CMakeLists.txt 的内容如下：

apps_cpp/app_edgeai/apps src 目录中的 CMakeLists.txt 内容如下：

这是我们的 CMakeLists,请看,期待您的答复。

我根据您的目录结构假设、您最初使用的是 edgeai-gst-apps、并且在那里使用的是 common.cmake。 我想我在这里做了一个错误的假设。

对于一个 Hello world 类型的应用程序、edgeai-gst-apps 可能 过于 复杂。 但是、它有一个 common.cmake 文件可能很有用--它设置了已知有效的库和包含路径。  

您是否还可以共享 common.cmake？ 您共享的 cmake 文件未包含任何正确的库或包含路径、因此我假设它存在于 common.cmake 文件中。  

我假设您正在针对目标进行编译。 如果内容不正确、请告诉我。
