QtOpenCLGL fails in Qt 4.8
Building QtOpenCL (latest git) on windows7 64bit with visual studio 2010 against the 4.8RC
The QtOpenCL and QtOpenCLGL libs build correctly and all the examples build - except the mandlebrot viewer (the only example to use the openGL wrapper)
@error C2491: 'QGLSignalProxy::staticMetaObjectExtraData' : definition of dllimport static data member not allowed
error C2491: 'QGLSignalProxy::staticMetaObject' : definition of dllimport static data member not allowed@
There is a note in glproxy.h that it shouldn't be necessary in future versions, and 4.8 does include changes to openGL.
have you compiled OpenGL with Qt before?
I think it's more complex than just adding a parameter when configuring Qt. There should be ActivePerl installed, OpenGL installed, environment variables defined and etc... look for some documentations on compiling OpenGL with Qt.
Yes, I'm familiar with openGL - this is specifically a QtOpenCL issue.
This static signal proxy doesn't seem to be used anywhere else in Qt and in this code it has a note saying it's basically a hack.
Since 4.8 includes a lot of specific openGL changes to allow multithreaded openGL I thought it might be breaking this code - and since it's a release candidate it might be breaking other more critical code.
However you can't report a bug in QtopenCL because it's lab code and not in the main repository
