나는 이 문제를 다음과 같이 해결하려고 노력합니다.
cmake --build . --target clean빌드된 파일을 삭제하고cmake --build .다시 실행하는데 사용됩니다 .위에 제공된 지침에 따라 디렉터리를 lib로 변경하고
ranlib libLLVMSupport.a.
그러나 이들 중 어느 것도 작동하지 않습니다. cmake --build .다시 실행하면 다음과 같은 결과가 나타납니다.

방법 2에서 lib/libLLVMSupport.a의 타임스탬프를 확인한 결과 변경되지 않았음을 발견했습니다. 즉, .a에 의해 재생성되지 않았음을 의미합니다 cmake --build ..
이 문제를 어떻게 해결하나요?
답변1
아카이브를 별도의 파일로 보관하면 어떨까요? 그런 다음 애플리케이션을 필요한 모든 아카이브에 연결합니다.
답변2
마침내 이 오류의 실제 원인을 찾았습니다.
cmake는 gnu gold 링커를 사용하고 libLLVMSupport.a 아카이브는 LLVM IR 코드로 구성되어 있으므로 문제가 발생하는 것은 당연합니다.
ld.lld-5.0으로 전환했더니 모든 오류가 사라졌습니다.
