Hi, I have problems running cl-opengl. I used quicklisp and loaded cl-opengl. Here a probably simple error: After trying (gl:get* :version) I get: NIL is not of type (OR SYMBOL FUNCTION), and can't be FUNCALLed or APPLYed [Condition of type TYPE-ERROR] Restarts: 0: [RETRY] Retry SLIME REPL evaluation request. 1: [*ABORT] Return to SLIME's top level. 2: [ABORT-BREAK] Reset this thread 3: [ABORT] Kill this thread Backtrace: 0: (CL-OPENGL-BINDINGS::GL-GET-PROC-ADDRESS "glGetString") 1: (CCL::CALL-CHECK-REGS CL-OPENGL:GET* :VERSION) 2: (CCL::CHEAP-EVAL (CL-OPENGL:GET* :VERSION)) 3: (SWANK::EVAL-REGION "(gl:get* :version)\n") I obtain exactly the same error on CCL 1.9 32-bit and 64-bit. Looks like something small or simple. Any advice appreciated. Best Regards Andreas Thiele
