glXCreateContextAttribsARB 찾을 수 없습니다 (OpenGL 4.2 드라이버, GLX 1.4)

Question

이상하게도 GLX 1.4가 있음에도 불구하고이 내 저장소에 없습니다.

여기에 합당한 설명이 있는지 궁금합니다. 이것은 일반적인 문제가 될 수 없습니다.이

하지만, 왜 안 glXCreateContextAttribsARB?

낯선 사람이라도 내가 무엇 을으로 처리하면 glXCreateContextAttribsARBPRoc이됩니다. 대체로 도움이 될지 궁금합니다.

이 예를 들어, 컴파일 :

`glXCreateContextAttribsARBProc glxccarb = 0;` 

Answer 1

당신이, 내가 직접이 이름의 함수를 호출 할 경우 "을 의미 가정"없습니다 "라고, 내 응용 프로그램이 연결되지 않습니다 ".

다소 다소 설계된 것입니다. libGL에서 직접 내 보낸 함수 목록은 늘어나지 않습니다. 그렇게했다면, 새로운 libGL로 익스포트 된 함수에 링크 된 앱은 이전 libGL에 대해서도 실행하지 못할 것입니다. 그 나쁜.

glXCreateContextAttribsARB은 다른 모든 확장 기능과 마찬가지로 glXGetProcAddressARB을 사용하여 조회해야합니다. 더 나아가서는 GLEW을 사용하면이 세부 수준에 대해 다시 걱정할 필요가 없습니다.
