Undefined external "macpib"; undefined external "mac_mlmesetreq ::? Relay errors

Copy the sensordemo folder to the samples directory. After the project is compiled, the following error occurs:

Error [e46]: Undefined external "mac_mlmesetreq ::? Relay "referred in mac_beacon (D: \ Texas Instruments \ ZStack-CC2530-2.3.1-1.4.0 \ projects \ zstack \ libraries \ timac \ bin \

The following error occurs after the project compilation is started:

Error while running linker

 

 

Solution:

I also encountered this problem. On http://e2e.ti.com/, I found the solution: Add file: mac_pib.c (under the high level directory) IN THE machigh level of the work space, and recompile it.
