Clang으로 컴파일 할 때 64 비트 Mint OS에서 32 비트 라이브러리를 찾지 못함

Question

방금 ​​Clang 3.5를 64 비트 Mint OS (버전 17)에 설치했습니다. 내 프로그램을 32 비트로 컴파일하려고하는데, 문제가있다.

: 나는 다음과 같은 출력을 얻을

$ clang++ -m32 -Wl,--verbose test.cpp | grep libgcc 

:

#include <iostream> 

int main() 
{ 
    std::cout << "Hello" << std::endl; 
} 

내가 다음 명령을 실행

나는 다음과 같은 코드를 사용하여 내 홈 디렉토리에 test.cpp라는 파일이

내가 할 수있는 모든 인터넷 검색 및 자체 조사를 수행했습니다. 왜이 간단한 예제가 작동하지 않는지 확인하십시오. 아무도 제가 누락 된 걸 알아낼 수 있습니까?

Answer 1

multilib g ++ sudo apt-get install g++-multilib을 설치해야합니다.

g++-multilib도 libc6-i386과 같이 필요한 모든 종속성을 설치해야합니다.

Answer 2

여기에 연타로 크로스 컴파일 할 때의 확인 작업은 다음과 같습니다

• 는 32 비트 (86) C++ libs가 설치되어 있습니까? (가지고 계신 것으로 보이지만 그냥 확인하십시오.)

• --sysroot=<location of your 32-bit multilibs>을 사용해보세요. 이렇게하면 하드 코드 된 경로를 사용하는 대신 특정 디렉토리에있는 bin, 및 include 디렉토리를 검색하도록 지시합니다.

• 포함 및 lib 디렉토리가있는 곳에서 clang에게 더욱 구체적으로 알려면 -I 및 -L 옵션을 사용해보십시오.

• 위의 경우 모두 최악의 경우 : -B <path> 옵션을 사용하여 clang에게 구체적으로 사용할 링커를 알려줍니다. 이 옵션을 이전 옵션과 함께 추가하십시오. 자세한 test.cpp` -합니다 (-B 옵션이 적용되지 않습니다 있지만)
