Problem in building

[suestorm]

I just wanted to build the project of the Jennic Zigbee demo application from the CD. The code should be no problem.
But when built, the build log showed:
"-------------- Build: Debug in JN5121_HomeDemoController ---------------
Linking console executable: ..\JN5121_Build\Debug\JN5121_HomeDemoController.exe
or32-elf-ld: cannot open linker script file AppBuild_JN5121.ld: No such file or directory
Process terminated with status 1 (0 minutes, 0 seconds)
0 errors, 0 warnings"
What does it mean? Or I didn't setting some path?Where to set it?
