"hal_int.h" Unsupported Compiler cc2538 PER CCS

Hello all,

Attempting to write a simple application directly interfacing with the RF transceiver on the cc2538 chipset. I have used the PER software download files to start doing initial testing - but cant seem to get the project built. Of the many header files I have to include in the project, one is "hal_int.h"

Here is the error I get:

#35 #error directive: "Unsupported Compiler"

This is being built on CCS V5. The only thing I can think of is that these files were written for IAR and it doesn't port? I thought

#elif (defined(ewarm) || defined(__ICCARM__))

ICCARM would be defined as the compiler as it is an ARM compiler being used. Any insight/direction is greatly appreciated!

Thanks,

CB
