TM4C1290NCPDT: CCS suddenly getting "uint32_t" is undefined.

Part Number: TM4C1290NCPDT
Other Parts Discussed in Thread: EK-TM4C1294XL

Tool/software:

I don't know what I did while editing but suddenly I start get a whole bunch of this error:

"C:/TI/tivaware_c_series_2_1_4_178/driverlib/timer.h", line 245: error #20: identifier "uint32_t" is undefined

I don't know where to start looking to fix this.

Thanks

Doug

    Hi Doug,

      Please make sure in your application where timer.h is included, you also have the below include. 

    #include <stdint.h>

    If you believe you have the above header file included already and still have the error then make sure the stdint.h file in the include path of your CCS project settings.

    Hi Charles,

    Yes, I've had "${CG_TOOL_ROOT}/include" in my project from the very beginning.

    Next thought?

    Thanks, Doug

    Hi Doug,

    Check if ${CG_TOOL_ROOT}/include expands to a valid location. 

     

    As I have shown in the last reply, do you find the stdint.h in the file system? Below is where I find stdint.h for my installation per my CCS and compiler version. 

    If everything is at the right place then i will suggest you try:

    - Create a new CCS workspace

    - Import the simple hello example at C:\ti\TivaWare_C_Series-2.2.0.295\examples\boards\ek-tm4c1294xl\hello

    - Compile the hello project. Do you have the same problem? The hello example uses uint32_t type.

    Hi Charles,

    I've been fixing other errors I'd been getting on compile, and magically the problem went away.  Probably a syntax error somewhere that screwed things up

    Thanks, Doug
