Error unresolved symbols remain.

Hi Dru,

Have a look at the wiki link below.  This should show you where the include options/paths and variables are located.   See where those functions/objects get defined ... this will point you to the library/file that CCS can't find.

http://processors.wiki.ti.com/index.php/Include_paths_and_options

Best Regards,
Lisa

I have the variables defined in other files in the project, I'll list them below:

in a file called "cpu.h" I have:

extern unsigned long CPUcpsid(void);
extern unsigned long CPUcpsie(void);
extern void CPUwfi(void);

interrupt.c has a #include "cpu.h" 

In "sysctl.h" I have:

extern void SysCtlDelay(unsigned long ulCount);

sysctl.c has a #include "sysctl.h"

These files are all part of a TI library for the LM3S8962 chip.

Symbol                   First referenced in file

CPUcpsid               ./src/interrupt.obj
CPUcpsie               ./src/interrupt.obj
CPUwfi                   ./src/sysctl.obj
SysCtlDelay           ./src/sysctl.obj

Hi Dru,

ok, have a look at the library section of that wiki and double check things ...

Best Regards,
Lisa

I know how to add the libraries, below is a screenshot of my properties. My problem is that I don't know what library I should be adding for these tools or if that's even the problem.

Hi Dru,

I believe you have a syntax problem in the lines you added .....  what exactly are you trying to do/how are your variables defined?  I think you are not nesting your variables correctly for example ...

Best Regards,
LIsa

I didn't add any lines of code to those files, all of those files are pre written TI code. I am attaching the files in question.

Hi Dru,

I mean the line you seem to have added to the library search path for example ....

Best Regards,

Lisa

That library is in my workspace, so when I selected it to add from my workspace that is the automatic syntax that came up. Is it incorrect?

Dru Steeby said:

Symbol                   First referenced in file

CPUcpsid               ./src/interrupt.obj
CPUcpsie               ./src/interrupt.obj
CPUwfi                   ./src/sysctl.obj
SysCtlDelay           ./src/sysctl.obj

Basically the error is saying that the linker cannot find definitions for those symbols. Looking at the Stellarisware package, the first 3 symbols are defined in cpu.c and the last one is in sysctl.c (found in C:\StellarisWare\driverlib). These are part of the driverlib and typically users simply link in driverlib to their project to resolve these references. It looks like you are instead adding those source files directly to your project. That should be ok as well but either the files have been modified or do not have those function definitions for some reason.

So if you're adding these files directly to your project I suggest checking the .c files to make sure there are definitions for all those symbols. Or you could simply remove those files and instead link in the driverlib by adding it to the Linker File Search Path (--library option).

If these suggestions do not get you going, please copy and paste the output of your CCS build console here (both compiler and linker steps), so we can see the exact source files and libraries in your project.

So this is another project that I'm working on, but I'm having the same problem. Here is the output of the build console:

**** Build Finished ****

Some of those varibles I have defined in a global.c and global.h file that I have on my main workspace and are used in my main file called EDM_2833xFlash.c that is also on my main workspace. All of the DSP2833x_(name).c and  DSP2833x_(name).h files are located in an include directory off of my main workspace. In my compiler include options(Properties > Build > C2000 Compiler > Include Options) I have included both the workspace and the include directory. The same applies for the Linker options in the "File Search Path"

I'm not sure what I'm missing here, why is it that the linker cannot find these definitions?

Thanks, I forgot to include my cmd file, that fixed all those warnings. I'm installing the controlSUITE right now, but what about the errors like this one:

_velocity          ./EDM_2833xFlash.obj

I have that varible (and several others) defined in a global.c and global.h file that are included in my project workspace.

Thanks,

-Dru 

Dru,

If the file <global.c> somehow failed to compile, the linker will not find its .obj and will throw the error. I would repair all the controlSUITE dependencies before attempting to solve this particular one.

Regards,

Rafael

I added all of the files from the controlSUITE and the errors went away, the only ones I have remaining are from my global.c and global.h files:

Nevermind, I fixed the global.c errors.

So back to the other project I was working on, with the error:

I have the unmodified files (cpu.c and sysctl.c) added to my project along with their headers and I still get the unresolved symbols error. Here is the output of my build console:

Hello Dru,

I have a similar problem on TMS320C5505, as described above.As you said, all the warnings got fixed when you included cmd file,may I know where you found that cmd file.

.

Please check the error screen attached.

Thanks

hi
i found an error an cant able ale to resolve.
