我面临与此处相同的问题：使用 LTO 版本 6.0 而不是预期的 8.1 生成
我尝试使用 docker 入门中的信息构建新的 2.0 传感器固件。启动后：
ninja pkgs
编译失败并显示库“libmovesense-coreD.a”是使用 LTO 版本 6 构建的，但预期是版本 8.1。
我还在 Ubuntu 19.10 上手动安装了 cmake 3.18.1 和 arm 工具链 2017_q4，但由于 LTO 包装器故障导致它在步骤 8/12 停止。
（...下面的一些行...）
我只是从 Movesense 主页复制了 cmake 命令并添加了 sample_app 的目录。这是我从 docker-container 中的 movesense/myBuild/ 开始的代码：
cmake -G Ninja -DMOVESENSE_CORE_LIBRARY=../MovesenseCoreLib/ -DCMAKE_TOOLCHAIN_FILE=../MovesenseCoreLib/toolchain/gcc-nrf52.cmake ../samples/plain_app/
为了提供一些信息，这是 cmake 的结果：
CMake Warning (dev) in CMakeLists.txt:
No project() command is present. The top-level CMakeLists.txt file must
contain a literal, direct call to the project() command. Add a line of
code such as
project(ProjectName)
near the top of the file, but after cmake_minimum_required().
CMake is pretending there is a "project(Project)" command on the first
line.
This warning is for project developers. Use -Wno-dev to suppress it.

我不关心“ABI info - failed”警告，因为最后一行说构建文件已被写入。也许这有点愚蠢。
在这里，“ninja pkgs”命令的完整输出（我删除了上面的那个）：

我只尝试在我的电脑上手动安装和构建 cmake 和 arm-toolchain，导致 docker-build 失败。
谢谢您的帮助！
