CCS/TM4C123GH6PM: Can't Compile Program Linking Error

Gordon Rankin3
Prodigy 40 points

Part Number: TM4C123GH6PM

Tool/software: Code Composer Studio

I'm currently  using the Launchpad Tiva C Series TM4C123G Evaluation Kit. I'm trying to  connect a NC-SR04 Ultrasonic device. I have found some code on the Line and I'm getting linking errors I have Cleaned up some other errors that were in the program If anyone can help that would be great. see Program below..

It looks like when the functions are not being linked I'm using Version: 7.4.0.00015 of ccs I have removed the all functions from the program to see if it  would and it will compile with out them..

Program:

#include <stdint.h>
#include <stdbool.h>
#include "stdlib.h"
#include "inc/hw_ints.h"
#include "inc/hw_memmap.h"

    Hello Gordon,

    Issues like what you are seeing tend to be due to the project not being properly setup. Sometimes the easiest way to solve it is to abandon the project and remake a fresh one. That said, to try and help you figure out what could be missing in your current project I would need screenshots of the following menus in the CCS Project Properties:

    • Project Properties -> Build -> ARM Compiler -> Include Options
    • Project Properties -> Build -> ARM Linker -> File Search Path
  • 0

    Link in the library.

    Get rid of the bloody red coloring please.

    See Attached...As per your request Thank for your help.. The Reason I want to continue with this file is that it will give me a better understanding of how CCS works trying to make a existing program work. I know the linker is not finding  files or folde r

    Hello Gordon,

    Ah I think I see your problem. You don't have the driverlib.lib file linked to your ARM Linker -> File Search Path tree. It goes under the "Include library file or command file as input". The link we use on TivaWare is "${SW_ROOT}/driverlib/ccs/Debug/driverlib.lib" but that depends on SW_ROOT resolving to the C:\ti\TivaWare_C_Series-2.1.4.178 folder. So adjust that as you need to for your project.

    I think beyond that you should be okay on the others, but let me know if you still have build errors when driverlib is linked up.

    Thank you Ralph you have been a great help.. TI should have a quick start guide that lets you know what files are needed and where to point to for compiling a program. Specially  if your a new  to TI MCU's would save a lot time..once again Thanks for your time and patience...
