CC3200: SDK 1.3.0 - ltoa() in OtaClient.c - function declared implicitly

Part Number: CC3200

I'm not able to compile the OTA library in the SDK 1.3.0 because of this error:

"function ltoa" declared implicitly" (2x)

I've added an include to "stdlib", "stdio.h" and ""string.h" without success.

This is one of the failing calls:

ltoa(13 /* {"path": "/"} */ + strlen((const char *)pVendorDir), (char *)&ReqDirCmdBuf[strlen((const char *)ReqDirCmdBuf)]);

Thank you for your help,

Carsten

I've tried at a different PC with a fresh SDK installation and got the same error. What am I missing here?
(I've added some missing function prototypes before to reduce the error messages...)

Hi Carsten,

You're talking about the library located within the SDK at: C:\ti\CC3200SDK_1.3.0\cc3200-sdk\simplelink_extlib\ota

Correct?

Are you importing this library into CCS? Are you copying the library into your workspace when importing?

I have tried importing/building within CCS on my end with no issues.

Thanks,
Kevin

Yes, that's the library. I'm opening it with IAR Embedded Workbench IDE (ARM 8.20.2) and got these errors:

I'm able to compile all other libraries this way. I've reduced the errors to the "ltoa" ones by creating the function prototypes in the header file.

Thank you for having a look at this problem.

I've tried with CSS and was able to compile the ota.a, but if I'm using it within my IAR project, I've got this error...

I've done another test with a fresh installation of SDK 1.3.0 and IAR 7.80.4 with the same result.

The "ltoa()" function in CCS can be found in the "stdlib.h", but not in the IAR project (there is no ltoa function in the IAR stdlib.h)

Anyone able to reproduce this probem with the IAR project?

Hi Carsten,

I have tried this on IAR and experience the same issue, but have not figured out a solution. It's most likely something to do with missing dependencies/includes.

I find it odd that IAR produces errors for missing function prototypes when those functions are used within that same .c file and therefore shouldn't need prototypes. I would focus on fixing the missing ltoa function dependency as it might be setting off the "missing prototype" errors.

Best,
Kevin

Thank you for your confirmation and your suggestion, but I'm not sure where I start searching for the ltoa function because CCS uses it from the stdlib.h and in the IAR stdlib.h, there isn't this function?

Hi Carsten,

That's correct, I do not see an ltoa() declaration within IAR's stdlib.h

C:\Program Files (x86)\IAR Systems\Embedded Workbench 8.0\arm\inc\c\stdlib.h

Maybe there's a way to include the stdlib.h ccs uses within your IAR project, but I'm not certain.

Are you opposed to using CCS over IAR?

Best,
Kevin
