c++ - ld: library not found for -lGL on Mac

Question

从https://github.com/openglredbook/examples 下载了OpenGL编程指南的样例代码，但是运行的时候报错，在build文件夹运行cmake .. 报错如下(运行环境是Mac)：

然后运行make 报错如下：

[  6%] Built target vermilion
[ 15%] Built target glfw
[ 16%] Linking CXX executable ../bin/12-imageprocessing
ld: library not found for -lGL
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[2]: *** [../bin/12-imageprocessing] Error 1
make[1]: *** [CMakeFiles/12-imageprocessing.dir/all] Error 2
make: *** [all] Error 2

在网上搜了好久但是都没有解决，大家知道这是怎么回事吗？

Answer 1

문제가 해결되었습니다. CMakeLists.txt 파일의 26번째 줄에서 https://github.com/openglredbook/examples/blob/master/CMakeLists.txt#L26를 삭제하면 make가 성공합니다. GL rt dl

Answer 2

이 예제를 다운로드했는데 Windows에서 성공적으로 실행될 수 있습니다.
사진과 같습니다.
cmake의 메이크 과정에서 Visual2013을 선택했다는 관계자분도 말씀하시길

Visual Studio 2013 사용 프로젝트를 열어서 컴파일

이러한 불필요한 오류는 무시하고 bin 폴더를 열어보면 실행파일도 많이 있는 것을 확인할 수 있습니다

이 실행 파일을 엽니다

귀하의 플랫폼은 Mac 플랫폼이므로 공식 웹 사이트에도 cmake를 사용하라고 나와 있습니다. Unix makefile도 성공적으로 실행할 수 있습니다. 나처럼 공식 웹사이트에 가서 cmake의 GUI 버전을 다운로드하고 Mac OSX를 선택할 수 있습니다. 그런 다음 올바른 경로를 입력하고 사용하려는 생성기를 구성하십시오. 저는 Visual 2013을 사용하고 싶기 때문에 Visual 2013을 선택했습니다. 상황에 따라 선택해야 합니다.

그런 다음 생성기를 열어 전체 프로젝트를 만들면 마지막으로 bin 디렉터리에 실행 파일이 생성됩니다. 마치다!
