Part Number: TM4C1294NCPDT
Other Parts Discussed in Thread: SYSBIOS

Tool/software: Code Composer Studio

Hi,

While compiling my program in CCS, I am getting the following error.

"unresolved symbol main, first referenced in C:\ti\ccsv6\tools\compiler\arm_15.12.3.LTS\lib\rtsv7M4_T_le_v4SPD16_eabi.lib<args_main.obj> " .

What to do to resolve this? Please help me to get out of this.

 

Regards

Sandra

    Sandra,

    The message is indicating that the symbol "main" is unresolved. Do you have a main() function in your project? 

    I see that you are working with Tiva TM4C part. If you are a new user, I would suggest importing and starting first with the examples from Tivaware.

    Hi,

    Thank you for the reply. I took the tcp echo project from the sample projects and integrated Modbus slave stack on top of it. I included the files:

    #include <string.h>

    #include <xdc/std.h>

    #include <xdc/runtime/Error.h>

    #include <xdc/runtime/System.h>

    #include <ti/sysbios/BIOS.h>

    #include <ti/sysbios/knl/Task.h>

    #include <ti/drivers/GPIO.h>

    #include <netmain.h>

    #include <_stack.h>

    #include <_oskern.h>

    The include search path in compiler options is given as shown below:

    The file search path in linker options is given as shown below:

    The error console is as shown below:

    Did I miss any library file? How can I find where the error is? Please guide me to find the cause of error.

    Regards

    Sandra

    Is there a source file that contains a main() function in your project? In the tcpEcho example, the file tcpEcho.c has a main(). Are you using that file as-is in your project? If you are not, then you need to make sure that there is another source file with a main() function.

    Hi Aarti,

     

    We have no other main function in source file other than the “tcp_echo.c”. We are using same tcp_echo project and modified the tcpHandler() function alone to support Modbus tcp protocol. Inside the tcpHandler(), I just configuring the target channel and using timer based polling for any incoming packet on the channel. If any incoming packet is available, call-back function will be called for processing the incoming packets.

     

    Can you please quickly help me  to resolve this issue?

    Regards

    Sandra

    Hi Aarti,

    Thank you for your reply. In one file main was redefined. It is solved. Thank you for your help.
