QtOpenCl "undefined reference" make errors

So I downloaded the ATI Stream SDK. I don't have a gpu now so I use the '-device cpu' and got the programs/examples in the OpenCl directory working by adding the directory to LD_LIBRARY_PATH etc.

Now the problem is when installing QtOpenCl.

The configure script gives me:

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.

Make gives me:

Tried it using the '-no-openclgl', but none of the examples etc are compiled.

I'm using ubuntu 10.04 using the Qt which is installed from synaptic.

I'd guess you aren't linking the OpenCL runtime. The QT library is making calls to those functions but they are not, then, defined in another file. You must link in "that" file to solve your problems.
