I apologize for the inconvenience. This is a unfortunate delayed rebranding from AMD Stream to ATI Stream. Instead of leaving both branding messages out there, the decision was made to switch the naming. I totally understand that this causes a incompatibility with current apps. SDK 1.4 is due out in early March (next 2 weeks or so) and syncs up to the new CAL library names.
Once again, sorry about the incompatibility. This was a one time event to make sure everything was synced up for the future.
You only need to rename aticalcl and aticalrt to amdcalcl and amdcalrt, respectively.
Of course, I suppose you will have to rename them back once 1.4 comes out.
