The CAL++ library has been just released. Project homepage is located here http://sourceforge.net/projects/calpp/ .
The project consist of two main components. One is C++ binding for CAL ( it's really much easier to develop new CAL applications using bindings ) and second is C++ to IL generator/compiler.
The C++ generator/compiler has syntax very similar to OpenCL ( with few necessary exceptions ). Also it supports all devices which can run CAL kernels ( finally OpenCL like language for 3xxx ).
