build attribute vendor section TI missing in....

Most likely the library IQmath.lib isn't actually needed in the "good" case, so the problem is not discovered.  Could you examine the linker map file for the "good" case to verify that those four object files from IQmath.lib are not used?

The bad project is linking in different files.  So, it is possible that it is bringing in different members of the IQmath library.  And those library members have the problem.

Try these commands:

% ar2000 -x IQmath.lib IQ15div.obj
% ofd2000 IQ15div.obj

The output of ofd2000 should include something similar to ...

Build Attributes in "$build.attributes"

Format Version: 'A'

<0> Vendor Name: "TI" (Texas Instruments, Inc.)

Tag_File:
Attributes:
Tag_Producer_Name Assembler
Tag_Producer_VMajor 7 (Producer Major Version + 1)

Tag_Producer_VPatch 3 (Producer Patch Version + 1)
Tag_ISA 1 (C2700)
Tag_Memory_Model 1 (small)
Tag_Amode 2 (No Amode)

Do you see something similar?  If so, post it.

Thanks and regards,

Archaeologist,

You were correct, the library wasn't actually used in the good project.

Georgem,

Output didn't have a build attributes section.  See below:

I'm gonna take a wild guess, and say that this library needs to be compiled with a more recent code gen tools version?  Would ya'll concur?

Trey

The tool version number is missing, but given that the object file was created in 2008, yes, this probably predates the use of build attributes.  However, the lack of build attributes won't affect the correctness of the library; you just get a warning, so you don't absolutely need a new copy of the library.

That's what I assumed but this code will be going external and I always like my projects to build for customers with no errors and warnings.

Thanks for the reply!

Hi,

I'm having the same "problem" with my C2000 project for a 2812 processor after updating to the v6.1.0 compiler: The code works but compiler warns about "build attribute vendor section TI missing in..."

So I downloaded the newest controlSuite and used the IQmath.lib from there - and still get the same warnings. I verified it with the ar2000 and ofd2000 tools and yes, the IQmath.lib from 2012-06-26 still does not have attribute information. Not satisfying...

So when you say that
  "The IQmath library must be built with an older version of the tools."
then you really mean that
  "the IQmath.lib requires to be built with an older version of the tools",
right?
(Sorry, I'm not a native english speaker, so "must be built ..." first sounded something like "has unfortunately and unnecessarily been built..." to me.)

If this is true this means that we:

• Either have to live with the warning for IQmath.lib - and ignore it.

• Or we have to disable the warning for all libraries - with the risk of missing relevant warnings for other libraries. Right?

The same warning is reported for the Flash2812_API_V210.lib library. That library seems to be missing in the controlSuite for the 2812 processor...

I understand your confusion.  Sorry about that.  Let me try again ...

That IQmath library is built with an older version of the tools.  This older version of the tools does not put any compatibility information in the object files.  Thus, the linker is correct to say it cannot check on possible compatibility issues.  Moreover, the IQmath library does not come from the compiler development team, so I cannot say anything about when this issue may be addressed.

Dear George Mock,

The above conversion say.. we need to Ignore the following error please help me..

Thanks In Advance..

Yes, you can probably ignore it.  This wiki article discusses the details.

Thanks and regards,

Dear George,

Thanks for the reply..I have one more doubt about the code generated..I am using the predefined Clark and park transformation..  in my control system developed in Simulink...

when i try to read the code developed by simulink ..i could not see any clark named .h file or .c file in the header files or Cfiles

Texas as provided predefined code in DMC libary...

#include "dmctype.h"
#include "clarke.h"

void clarke_calc(CLARKE *v)
{
v->Alpha = v->As;

v->Beta = (v->As + 2*v->Bs)*0.57735026918963; // 1/sqrt(3) = 0.57735026918963
}

This type of code is not generated by Simulink when i used the predefined block in the  embedded coder...how I need to assume now. Is simulink is generating the code for the predefined  block or not.

Or I need to link the DMC library  to simulink??

Thank you..

Vureli naveen

I have no expertise that is helpful here.  In fact, I know so little about this code that I cannot even direct you on where to go next.  This is code from TI?  If you downloaded it from some ti.com web page, does that page say where to go for support?

Thanks and regards,

-George
