QtOpenCl "undefined reference"는 오류를 만듭니다.

Question

그래서 ATI Stream SDK를 다운로드했습니다. 지금은 GPU가 없어서 '-device cpu'를 사용하고 LD_LIBRARY_PATH 등에 디렉토리를 추가하여 OpenCl 디렉토리의 프로그램/예제를 얻었습니다.

QtOpenCl을 설치할 때 문제가 있습니다.

은 '노 - openclgl'를 사용하여 시도했지만 등의 예 중 어느 것도 컴파일되지 않습니다 :

skkard@skkard-desktop:~/Applications/qt-labs-opencl$ ./configure 

This is the QtOpenCL configuration utility. 

Qt version ............. 4.6.2 
qmake .................. /usr/bin/qmake 
OpenCL ................. yes 
OpenCL/OpenGL interop .. yes 
Extra QMAKE_CXXFLAGS ... 
Extra INCLUDEPATH ...... 
Extra LIBS ............. -lOpenCL 

QtOpenCL has been configured. Run '/usr/bin/make' to build. 

만들기가 나에게 제공합니다

구성 스크립트는 저를 제공합니다.

나는 시냅스에서 설치된 Qt를 사용하여 우분투 10.04를 사용하고 있습니다.

Answer 1

OpenCL 런타임을 연결하지 않은 것 같습니다. QT 라이브러리는 이러한 함수를 호출하지만 다른 파일에 정의되어 있지 않습니다. 문제를 해결하려면 "그"파일에 링크해야합니다.
