qtopencl "مرجع غير محدد" ارتكب أخطاء

Question

لذلك قمت بتنزيل ATI Stream SDK. ليس لدي وحدة معالجة الرسومات الآن ، لذا أستخدم "-Device CPU" وحصلت على البرامج/الأمثلة في دليل OpenCL الذي يعمل عن طريق إضافة الدليل إلى LD_Library_Path إلخ.

الآن المشكلة هي عند تثبيت QTOPENCL.

يعطيني البرنامج النصي التكوين:

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.

اجعلني يعطيني:

جربته باستخدام '-no-openclgl' ، ولكن لا يتم تجميع أي من الأمثلة وما إلى ذلك.

أنا أستخدم Ubuntu 10.04 باستخدام QT الذي تم تثبيته من Synaptic.

Answer 1

أعتقد أنك لا تربط وقت تشغيل Opencl. تقوم مكتبة QT بإجراء مكالمات لتلك الوظائف ولكنها لم يتم تعريفها في ملف آخر. يجب ربط ملف "ذلك" لحل مشاكلك.
