TMS320F28388D: error #10234-D: unresolved symbols remain in DCL for CLA

I try to use the DCL function DF22 in a CLA code and get linking error.

The DCL_DF22_L1.asm source file is added to the include path.

Code:

/* shared CLA variables */
extern float uk;
extern float ek;

...

#include "DCLCLA.h"

..

//CLA variables
DCL_DF22_CLA ctrl1;

...

// run the full DF22 controller
uk = DCL_runDF22_L1(&ctrl1, ek);

...

Error:
