I was also getting the same problem.
This gets solved if the project is imported from the file->import->import existing project
and then pointing to the Chronos Sports Watch project from CCS folder from the ez430-chronos that was installed.
Turns out, this way the ez430_chronos_drivers.lib gets included in the project this way.
If importing the project by clicking on the welcome screen, the lib doesn't get copied and hence the missing symbols.
