问题描述
问题：
我正在尝试在我的 Ubuntu 18.04 PC 的 yocto 构建系统中构建 ot-br-posix。我从一开始就解决了许多错误，现在卡在与“Boost”文件夹相关的错误中。
说明：
我正在 Yocto 环境中从 GitHub 构建 OpenThread 源代码。 在 Yocto 环境中为我们的自定义板编译需要 OpenThread。因此，我为编译所需的所有信息创建了一个配方文件 (.bb)。 最近版本的 OpenThread 使用 CMake，它对我来说有点新。我从来没有更早地遇到过“Boost”。所以，“Boost”也是新的。所以我无法清楚地找出问题所在。
我在编译 ot-br-posix (OpenThread) 时遇到以下错误：
| CMake Error at /home/pandurang/projects/git/CustomBoard/build/tmp/work/cortexa7t2hf-neon-poky-linux-gnueabI/Otbr/git-r0/recipe-sysroot-native/usr/share/cmake-3.14/Modules/FindBoost.cmake:2132 (message):
| Unable to find the requested Boost libraries.
|
| Boost version: 1.65.1
|
| Boost include path: /usr/include
|
| Could not find the following static Boost libraries:
|
| boost_filesystem
| boost_system
|
| No Boost libraries were found. You may need to set BOOST_LIBRARYDIR to the
| directory containing Boost libraries or BOOST_ROOT to the location of
| Boost.
| Call Stack (most recent call first):
| etc/cmake/options.cmake:78 (find_package)
| CMakeLists.txt:37 (include)

|
| -- *** (OTBR_VERSION) *** Version: 0.3.0-b9565b4c-dirty
CMake 版本：3.14
我已经浏览了几个小时的其他人的解决方案，但找不到完全正确的答案来解决我的问题。我已经应用了以下链接中的一些解决方案，但没有帮助。
- CMake is not able to find BOOST libraries
- Cmake doesn't find Boost
- using cmake and boost. Unable to find the requested Boost libraries
- CMake cannot find requested Boost libraries
- How to handle "Cmake Error: Unable to find the requested Boost libraries"?
当我搜索 Boost 文件夹时，它在 recipe-sysroot 路径中，但不在 recipe-sysroot-native 路径中，我认为它是在 recipe-sysroot-native 路径中搜索。请参阅下面的 FIND 命令的输出：
pandurang@pandurang-desktop:~/projects/git/CustomBoard/build/tmp/work/cortexa7t2hf-neon-poky-linux-gnueabI/Otbr/git-r0$ find ./recipe-sysroot -name "boost"
./recipe-sysroot/sysroot-providers/boost
./recipe-sysroot/usr/include/boost
./recipe-sysroot/usr/include/boost/chrono/typeof/boost
./recipe-sysroot/usr/include/boost/hana/ext/boost
pandurang@pandurang-desktop:~/projects/git/CustomBoard/build/tmp/work/cortexa7t2hf-neon-poky-linux-gnueabI/Otbr/git-r0$ find ./recipe-sysroot-native/ -name "boost"
./recipe-sysroot-native/installeddeps/boost
pandurang@pandurang-desktop:~/projects/git/CustomBoard/build/tmp/work/cortexa7t2hf-neon-poky-linux-gnueabI/Otbr/git-r0$
编辑： 我已更新 _otbr 脚本如下： otbr_install() “-DCMAKE_INSTALL_PREFIX=/usr”更新为 “-DCMAKE_INSTALL_PREFIX=/home/pandurang/projects/git/Gateway/build/tmp/work/cortexa7t2hf-neon-poky-linux-gnueabI/Otbr/git-r0/recipe-sysroot/usr”。
通过上述更改，解决了与“Boost”文件夹相关的错误，现在出现了一个新错误：
