linker errors using DSPLIB c67x

Hi,
I have a board based on C6713 and am using some matrix functions in DSPLIB.
I get an error during the link process

**************************************
[Linking...] "C:\Program Files\C6000 Code Generation Tools 6.0.15\bin\cl6x"
-@"Debug.lkf"


undefined first referenced
symbol in file
--------- ----------------
DSPF_sp_mat_mul(float *, int, int, float *, int, float *)

C:\\Innovative\\M6713\\Examples\\AMBControl\\RingBuffer.obj
>> error: symbol referencing errors - 'ServoTarget.out' not built

>> Compilation failure

Build Complete,
2 Errors, 0 Warnings, 0 Remarks.
**************************************

These are the steps I have followed:

1. Dsplib installed to C:\CCStudio_v3.3\c6700\

2. Set the environment variable C_DIR=C:\CCStudio_v3.3\c6700\dsplib\include

3. Add #include to my code

4. Add rts6700.lib and dspc67x to my CCS project

Not sure what else to try, so I would appreciate any help from the group.

Thanks,

Hi,
DSPF_sp_mat_mul can be found in dsplib.lib
so you need to include this library.

Regards Start a New Thread

Simon,

In the ccs project/build options/...

contains a line to list all the library directories, separated by semicolons.

Has that line been updated to include the directory that contains the
DSPF_sp_mat_mul.lib library?

Is the ';' missing from the end of the line that is calling DSPF_sp_mat_mul?

Hi Richard,
Thanks for those suggestions...I made the changes below but still get the
same error message.

I added this line to Build Options -> Linker ->Libraries
-i"C:\CCStudio_v3.3\c6700\dsplib\include"

>

I tried using this line #include
"\CCStudio_v3.3\c6700\dsplib\include\DSPF_sp_mat_mul.h" instead of #include
and there was no change in my error message

I also have the following lines in a .cmd file for my project:
-stack 0x1000
-q
-i"..\..\Lib\Target"

-l csl6713.lib
-l HdwLib.lib
-l ModuleLib.lib
-l DspLib.lib
-l dsp67x.lib
-l dsp62x.lib
-l UtilLib.lib
-l NumLib.lib
-l TemplateBuilder.out
Let me know what you think?

Best regards,
Simon

Simon,

Are you building the project with C++??
If yes, does
DSPF_sp_mat_mul(float *, int, int, float *, int, float *)
match the signature in the 'DSPF_sp_mat_mul.h' header file??

Simon,

Sorry, I gave you the wrong lib name.
It is not DSPF_sp_mat_mul.lib
rather, it is DSPLIB.lib

Also, in looking at this:
> -i"..\..\Lib\Target"
>
> -l csl6713.lib
> -l HdwLib.lib
> -l ModuleLib.lib
> -l DspLib.lib
> -l dsp67x.lib
> -l dsp62x.lib
> -l UtilLib.lib
> -l NumLib.lib
> -l TemplateBuilder.out
>
I see a few problems.
1) the dsp62x.lib should not be included, as it is compiled for a different
processor.
2) unless the libraries are all in the same directory as your project (which *I*
would not expect them to be), it is unlikely that the linker will find any of them.
3) the CCS project build options should have the path for each library file
location.
4) the CCS project list of files should already contain these libraries in the
'libraries' section, so they are not needed in the .cmd file.
5) the CCS project/build options should already have the stack size, so it is
not needed in the .cmd file.

And now, the main answer to your problem....
6) the DspLib.lib contains the function DSPF_sp_mat_mul.
7) the DspLib.h file has to be included in the source, not DSPF_sp_mat_mul.h.

BTW:
I found everything I needed to answer your question(s) by searching at:
http://www.ti.com

Hi all,

Christophe: Sorry but I am just getting a bit confused...on my machine
DspLib.h is a library provided by Innovative Integration for their own bells
and whistles, and it is already linked into my project. I was following the
instructions in section 2.3.2 of spru657/spru657b to get the matrix math
header file into my project.

According to my .cmd file dsp67x.lib is already being linked in, and if I
understand this is where DSPF_sp_mat_mul should be defined in.

Mike: Yes. I am using c++, and my function call reads like the following:

DSPF_sp_mat_mul(K.ptrC, 4, 30, K.ptrXc, 1, K.ptrY);
where K.ptrC and K.ptryXc and K.ptrY are all (float *)...this matches
DSPF_sp_mat_mul(float *, int, int, float *, int, float *)

Richard: Yes, indeed the linker command file I was posted was weird the
first time I looked at it too, I tried taking out the dsp62x.lib reference
but I get a whole slew of more linker errors I think some of the Innovative
Integ. libraries use functions in there?? When I leave it in it doesn't hurt
me.

Any more of your thoughts are most welcome,

Best,
Simon

Simon,

Perhaps I was not clear, when I mentioned how to fix the problem.

add the following to your source file.

#include "DspLib.h"

Hi Richard,

when I add #include I get the same error btw I did a file search
for DspLib.h and found it in these 3 locations

1) C:\CCStudio_v3.3\C5400\dsplib\include
2) C:\CCStudio_v3.3\C5500\dsplib\include
3) C:\Innovative\M6713\Libraries\DspLib

I checked each one out and none of them contain the DSPF_sp_mat_mul
function. When I ran the C67xDSPLIB_v200.exe (from sprc121) installer I told
it to put everything in \CCStudio_v3.3\C6700\dsplib\.

Any more ideas,
Simon
