All I am trying to do is add OpenCL to a QT project. My OpenCL files are in c:/opencl   c:/opencl/include/CL/cl.h c:/opencl/lib/x86/OpenCL.lib According to what I read here [qt-project.org] if you have a .lib and a .dll you should link dynamically and I do have a .dll. c:/opencl/bin/x86/OpenCL.dll I setup my .pro file: LIBS += -lOpenCL LIBS += -LC:/opencl/lib/x86 INCLUDEPATH += C:/opencl/include I include the header file: #include <CL/cl.h> QT intellisense incorporates the header file !http://i.troll.ws/83b43d1e.png()! The application builds and runs fine. However, as soon as I try to call any of the functions in the library I get linker errors: LNK2019: unresolved external symbol clGetPlatformIDs referenced in function main LNK1120: 1 unresolved externals
