我正在使用 buildroot，我正在尝试交叉编译此处找到的 AWS IOT cmake 库: https://github.com/aws/aws-iot-device-sdk-cpp
我有另一个 buildroot 生成文件(正确编译)来自这里的不同 AWS sdk: https://github.com/aws/aws-sdk-cpp
我复制了另一个 makefile 并尝试修改它来构建，但我收到以下错误:
...
-- Detecting CXX compiler ABI info
-- Detecting CXX compiler ABI info - done
-- Detecting CXX compile features
-- Detecting CXX compile features - done
CMake Error at CMakeLists.txt:9 (message):
In-source builds not allowed. Please make a new directory (called a build
directory) and run CMake from there. You may need to remove CMakeCache.txt
and CMakeFiles folder.

生成文件:

如何让 Buildroot 编译这个库？谢谢。
最佳答案
在 *.mk 中添加以下行应该可以避免此问题:
AWS_IOT_DEVICE_SDK_CPP_SUPPORTS_IN_SOURCE_BUILD = NO
