gcc 환경 변수를 인쇄하는 bash 명령

명령줄에서 모든 GCC 환경 변수(디렉토리, 라이브러리를 포함한 경로)를 인쇄하는 방법이 있습니까? 즉, 모든 bash 환경 변수를 제공하는 "printenv"와 유사합니까?

답변1

gcc -print-search-dirs

바이너리에 대한 다양한 디렉터리 목록( gcc설치 디렉터리, 프로그램이 검색되는 디렉터리, 라이브러리가 검색되는 디렉터리)이 출력됩니다.

echo | gcc -v -E -

실제 경로 변수( COMPILER_PATH, )와 LIBRARY_PATH헤더 파일에 사용된 디렉터리가 출력됩니다.gcc

답변2

일반적으로 사람들은 gcc -v그것을 사용합니다.

gcc -vNo file to compile은 단지 GCC의 컴파일 시간 구성과 기본 대상 아키텍처를 제공하지만, 컴파일할 파일( )을 제공하면 gcc -v test.c더 많은 정보가 표시됩니다. 다음은 출력 예입니다.

Using built-in specs.
