ccsv6 linker error TI compiler

srikanth hungund

Hello,

I am using TMS570 Hercules USB stick with TI compiler.

After building the project in ccsv6 I get the following error during linking,

undefined first referenced
symbol in file
--------- ----------------
main C:\ti\ccsv6\tools\compiler\arm_5.1.6\lib\rtsv7R4_T_be_v3D16_eabi.lib<args_main.obj>

I also have main.c included for build in the project but linker is unable to find the reference.

Ialso checked library file rtsv7R4_T_be_v3D16_eabi.lib it exists inside the path mentioned in the error log.

Any solution to resolve this issue?

Hello,
The error is actually that there is no main function (not source file) defined in your project (which is being referenced by the run-time library). If you don't have a main and which to set the entry point to something different, you can change that in the in the Linker options under the Build properties: http://processors.wiki.ti.com/index.php/Projects_and_Build_Handbook_for_CCS#Build_Properties

Thanks

Hello,
As I checked I have the main( ) function in sys_main.c and corresponding object sys_main.obj is also generated still I get the same error and i didnt get exactly where the linker options are located in build properties to cross verify the main is referenced correctly.

Any solutions to resolve this?

Thanks

If you have a main() function in your project then it should work. Can you provide a reproducible test case?

Thanks

hi Ki,
This error comes only when I compile the sources using command line using gmake -k all.but in IDE it builds fine
Is there any solution to build the files in command line.
