unresolved symbols remain

Other Parts Discussed in Thread: CONTROLSUITE

Hi, I'm implementting ModBus on Concerto, found the modbus libraries from github.com which was implemented on delfino (C2000). I have included all the header files and source files to my project. Initially got many errors and from some research in the forum I solved few. Now I'm struck in solving this error

error #10234-D: unresolved symbols remain
error #10010: errors encountered during linking; "Modbus_2.out" not built
gmake: *** [Modbus_2.out] Error 1
gmake: Target `all' not remade because of errors.

Description Resource Path Location Type
unresolved symbol _InitSysCtrl, first referenced in ./main.obj Modbus_2

I'm not understanding how to deal with it. I have cross checked all header and source files, everything seems ok! Help needed.

Unresolved symbols occur when you call a function and that function is declared extern but the definition of the function isn't found in the linking step.

InitSysCtrl() should be available in the device default headers, file *_SysCtrl.c. Take a look at the build settings of your project, are you using CCS or something else to build? see if you can search for the InitSysCtrl in the sources directory and include the needed files.

I haven't looked at the MODBUS Git build structure that you are referring to. Worst case you should be able to find the needed headers from ControlSuite.

I'm using CCS6.1.1 to debug my project. I have included the .h and .c files for SysCtrl, even then getting the error. Don't know what else I'm missing. Please have a look at the below screenshot.

Thank you Santhosh! I solved it. I forgot to add the .c file. Now I can debug the code without any errors.

Vinod,

cool. when you get a chance keep us posted on what you are trying to do with modbus on Concerto, it definitely seems interesting. and it looks like you are porting the code from F28335 to Concerto ARM or Concerto C28x or both?

Best Regards

Hi Santhosh! We are trying to implement it on C28x. Will update once we are done with it.

Regards,

Vinod!
