BB 配方中的 CMake

Question

我正在为cpsumon 开发 OpenEmbedded Layer，这是一个用 C 语言编写的用于监控 Corsair AXi 电源单元 (PSU) 的工具。

我的层的代码可以在https://github.com/bernardoaraujor/meta-cpsumon找到

我在 Make 和 CMake 方面的经验非常有限，我无法理解以下错误：

据我了解，| make: *** No rule to make target 'install'. Stop. 表示 BitBake 正在尝试使用 --target install 执行 cmall，并且由于某种原因 make 无法执行 install 任务。对吗？

我不明白该问题是否必须在 CMakeLists.txt 或 cpsumon_git.bb 中修复。 非常感谢任何帮助！

Answer 1

cpsumon 的 CMake 脚本实际上并未将库安装在任何地方，因此生成的 makefile 不包含 install 目标。

因此，当do_install 任务执行make install 时，您会收到来自make 的错误提示

make: *** No rule to make target 'install'.
