    Hi,
    The function SysCtlClockGet() is not anymore allowed for TM4C129x micros. Instead, the usual setting function returns an long representing your frequency or 0 if not succeeded to set it properly. See the driverlib code for more info...
    Also, the function SysCtlDelay depends on your tools, since it is written in assembler. If you use CCS, then in the predefined symbols tab of compiler configuration, you must add this define: ccs="ccs". Again, look into driverlib source code if you use another toolchain
