cygwin에서 clang을 사용하여 C++ 파일을 컴파일하려고 하는데 생성된 실행 파일이 실행되지 않습니다. Cygwin에서 런타임 오류가 발생합니다.
Cygwin runtime failure: a.exe: Invalid relocation. Offset 0x2fd4bce73 at address 0x1004010e9 doesn't fit into 32 bits
샘플 코드 - proba.cpp:
#include <iostream>
using namespace std;
int main(void)
{
cout << "Hello, World!";
return 0;
}
다음으로 컴파일:
clang++ proba.cpp
오류나 경고 없이 컴파일이 완료됩니다.
clang은 소스에서 컴파일되었습니다. 최신 릴리스(8.0.0)와 git 버전(26.03.2019)을 사용해 보았습니다. 둘 다 출력을 실행할 때 동일한 오류를 생성합니다.
clang 설치 절차는 다음과 같습니다.
git clone https://github.com/llvm/llvm-project.git
mkdir build
cd build
cmake -G "Unix Makefiles" -DCMAKE_BUILD_TYPE=Release -DLLVM_ENABLE_PROJECTS="clang;compiler-rt;lld;" -DLLVM_TARGETS_TO_BUILD=X86 ../llvm/
make -j4
make install
cygwin에는 proba.cpp를 작동 가능한 실행 파일로 컴파일하는 clang 패키지(버전 5.0.1)도 있습니다. 이를 사용하지 않는 이유는 SystemC 라이브러리(https://www.accellera.org/downloads/standards/systemc) 올바르게. gcc(7.4.0)로 컴파일할 때 모든 테스트가 통과되는 것과 대조적으로 'make check' 중에 실패하는 테스트는 거의 없습니다.
또한 소스에서 컴파일된 clang 드라이버는 g++를 링커로 사용하는 반면 cygwin 패키지와 함께 제공되는 드라이버는 ld를 사용하는 것으로 나타났습니다. 나는 또한 clang 9가 g++ 대신 lld를 사용하도록 강제하지 못했습니다. (-fuse-ld=lld는 g++에서 인식되지 않습니다)
clang은 cygwin과 함께 제공됩니다.

proba.cpp에 해당하는 C 파일을 컴파일하고 실행하면 clang 9에서 잘 작동합니다. 문서에서 제안한 테스트를 시도했습니다(https://clang.llvm.org/get_started.html):
clang --help
clang file.c -fsyntax-only
clang file.c -S -emit-llvm -o -
clang file.c -S -emit-llvm -o - -O3
clang file.c -S -O3 -o -
그들은 나에게 올바르게 작동하는 것 같았습니다.
나는 또한 성공하지 않고 다음을 시도했습니다.
clang++ -c proba.cpp -o proba.o
ld.lld proba.o -o proba.exe
ld.lld: error: proba.o: unknown file type
cygwin에서 clang 9를 사용하여 C++ 컴파일에 어떤 문제가 발생할 수 있는지 아는 사람이 있습니까?
cygwin에서 clang과 함께 lld 링커를 사용하는 사람이 있습니까?
cygwin에서 clang + lld 툴체인을 올바르게 설정하는 방법에 대한 힌트도 감사하겠습니다.
