柯南和树莓派，如何搭配使用？

如何解决柯南和树莓派，如何搭配使用？

早上好！

我正在重写这个问题，因为经过大量阅读和尝试失败后，我进一步研究了这个问题，但我再次被赌注。

我在这里试图帮助的是：使用 Conan 作为我的 Mac（使用 CLion）中嵌入式设备“RaspBerry PICO”的包管理器

与上一个问题不同的是，现在我正在创建一个包，而且我不只使用“独立”包管理器。

此“包裹”位于 github.com。要安装并尝试编译它，您还需要 Pico SDK。

一些事实：

• 没有 Conan 但有 SDK 的新 C++ 项目正在嵌入式设备上编译和运行。
• 没有 Pico SDK 的 Conan 项目编译正确。
• 我真的在配置文件上尝试了所有可能的配置，主要有两个配置配置文件会在构建过程中导致两个不同的错误：

第一个没有任何环境。这是因为在 CLion 上我没有添加任何环境，并且项目本身（没有 conan，但没有使用 SDK for pico）是正确的构建器。

ps。注释行是在 conan build . 之后解析相同结果的附加测试。

错误是这样的：

第二个配置文件配置基于 the example from conan.com（感谢@uilianres）并设置环境。：

使用命令 conan build . 解决不同的错误：

我也在这里做了所有的变体和测试，但一切都会导致这个错误。此外，我检查了工具链路径，并且是正确的。

我现在完全迷失了。 :(
