keil c166 error

Hi,everyone.

When I built my project, there were a lot of errors of L118 and I still can't solve it.

MCU:Infineon XC2267M

operation system:transplated ucos-II

A part of errors are as follows.

*** ERROR L118: REFERENCE MADE TO ERRONEOUS EXTERNAL SYMBOL: OSTime MODULE: os_time.obj (OS_TIME) ADDRESS: 00DEH
*** ERROR L118: REFERENCE MADE TO ERRONEOUS EXTERNAL SYMBOL: OSTime MODULE: os_time.obj (OS_TIME) ADDRESS: 00E2H
