Can't build Firmware in IAR Workbench

[arwsl]

Linking fails:

Error[e46]: Undefined external "?B" referred in bdb_Reporting ( C:\Texas Instruments\Z-Stack 3.0.2\Projects\zstack\HomeAutomation\AirSense\CC2530DB\
DIYRuZ_AirSense_Router\Obj\bdb_Reporting.r51 )

Error while running Linker

Any ideas what I can do?
