Tag_Long_Precision_Bits attribute error

Marcello,

I've split this thread since it's now appears to be a compiler/linker question more than a MathLib question.

I suspect your issue is related to the fact that in EABI type "long" is a 32-bit data type while under COFF the type "long" is 40-bit .  A good reference is here:

http://processors.wiki.ti.com/index.php/C6000_EABI_Migration

Here's a link to the original thread in case anyone is interested.

Brad

As Brad mentioned, I believe this is related to the usage of long data type. For instance, I used ofd6x (object file utility included with the code generation tools) to dump the c67pfastMath_elf.lib and see that this attribute is set to 3 for object files that have no long types and is set to 2 for object files that do have 32-bit long type.

What are the object files/libraries being passed to the linker? Are they all built for EABI and do they use long data types? It may help to look at tthe full linker command (all options/files passed to the linker).

Hi AartiG,

thanks for your follow up.

I am not sure how to tackle this and I might need a "detailed" guide to follow through...

The project is rather simple and there is only one single .cpp file compiled with a C style processing function:

// Host Alg wrapper shim headers
#include "TransModAAX_AlgProc.cpp"
#include <elf_linkage.h>

const AAX_EStemFormat kStemFormat = AAX_eStemFormat_Stereo;
const int kNumChannels = AAX_STEM_FORMAT_CHANNEL_COUNT(kStemFormat);

// The main algorithm entry point
extern "C"
TI_EXPORT
void AlgEntry( STransMod_Alg_Context * const inInstancesBegin [],
const void * inInstancesEnd)
{
TransMod_AlgorithmProcessFunctionStereo<kNumChannels, kNumChannels>(
inInstancesBegin,
inInstancesEnd);
}

No external libs are linked in apart from the c67pfastMath_elf.lib.

Here is the full linker command:

"${CG_TOOL_ROOT}/bin/cl6x"

-z -m"C:/svn/PlugIn_PT/AAX_SDK_1p0p5/SonnoxPlugIns/AAX_SonnoxTransMod/TI/TransModAAX_Stereo_Stereo_TI/../../WinBuild/Release/int/SonnoxTransMod.aaxplugin/TI/OxfordTransMod_Stereo_Stereo_TI/OxfordTransMod_Stereo_Stereo_TI.map" --warn_sections -i"C:/Program Files/Texas Instruments/c6700/c67xmathlib_2_01_00_00/lib" -i"C:/Program Files/Texas Instruments/c6700/c67xmathlib_2_01_00_00/inc" -i"C:/Program Files/Texas Instruments/ccsv4/tools/compiler/C6000 Code Generation Tools 7.0.5/lib" -i"C:/Program Files/Texas Instruments/ccsv4/tools/compiler/C6000 Code Generation Tools 7.0.5/include" --reread_libs

The main TransMod_AlgorithmProcessFunctionStereo function does not use any long type data.

It is essential that I get this lib working to finish my project in time for its deadline, and I am keen to try everything you suggest to fix it.

Thanks again for your help

Marcello,

Are you compiling with --abi=eabi option? Just confirming because it looks like you cut out the compile options shown in the link step. Is this the complete list of linker options or were some of it cut off as well?

Are you able to share all the files required to reproduce this error as it will be the quickest way to reproduce and investigate it. If you cannot share all the sources, how about the .obj file and full link command line so we can simply run the link command and reproduce the error? The object files may be sufficient to investigate the cause of the error. Also if you do not wish to post the files here on the forum, you can share it with me privately by starting a private conversation. Let me know if you prefer that method.

AartiG,

I guess that is the full, at least it is what is shown by the "All option" section of the Tool Settings->C6000 Linker page.

I don't think I can send you the project but I guess there is no problem with the object files.

I also rather start a private conversation. But How?

I just sent you a friend request. When you accept it, you can go to your Friends list and start a private conversation with me. In it you can attach a zip file with the required files.

Please be sure to zip up all files required to perform the link step (.obj, .lib etc). Also please copy and paste the full output of the CCS build console - this will show the files being passed to the link in addition to the options and the order in which they are passed.

Gotcha,

here is the full console output (there is no --abi=EABI):

I still cannot see the files being passed to the linker - looks like due to the long command line it is being saved in ccsLinker.opt instead of being output directly in the console. Could you please attach that file?

Also, as you mentioned you are not using --abi=eabi. If so you should be linking with c67pfastMath.lib (non EABI version) instead of c67pfastMath_elf.lib.

Ok,

here is the file requested:
