linker errors using DSPLIB c67x

Simon,

I just downloaded SPRU121, then extracted the files with winzip
then ran the self extracting file and had it install everything into:
C:\CCStudio\c6700\dsplib\include\

amongst the resulting files are:
DSPF_sp_mat_mul.h
DSPF_sp_mat_mul.h67

C:\CCStudio\c6700\dsplib\lib contains the library file:
dsp67x.lib
So, either your file search was incorrectly stated or you have some other very
serious problem with your computer.

These files are very visible when I extracted SPRU121.zip

Simon,

Here are the details, straight from the TI document SPRU657b.pdf,
Which is included as part of the SPRU121.zip file.

----------
2.2.2 Calling a DSPLIB Function From C
In addition to correctly installing the DSPLIB software, you must follow these
steps to include a DSPLIB function in your code:
Include the function header file corresponding to the DSPLIB function
Link your code with dsp67x.lib
Use a correct linker command file for the platform you use.
Remember most functions in dsp67x.lib are written assuming little-endian mode of
operation.
For example, if you want to call the single precision Autocorrelation DSPLIB
function, you would add:
#include
in your C file and compile and link using
cl6x main.c z o autocor_drv.out lrts6700.lib −ldsp67x.lib

Code Composer Studio Users
Assuming your C_DIR environment is correctly set up (as mentioned in
section 2.1), you would have to add DSPLIB under the Code Composer Studio
environment by choosing dsp67x.lib from the menu Project → Add Files to
Project. Also, you should make sure that you link with the run-time support library,
rts6700.lib.
----------------

*I* would properly update the CCS project/build options directory list rather
than messing with the C_DIR environment variable.

Simon,

I found DSPF_sp_mat_mul in dsplib.rts, rts file is a source library file, in this file the function in asm is defined, in the same directory, you should find the .h with the prototype, and also the lib file already compiled.
I suggest you do not add too many libraries without knowing what they contain, and keep the strict minimum.
If this still not work, try to extract the source code from the rts file and compile it with another funcion name, so you can see if this is due to your C++ interface or library problem.

Subject: Re: Re: [c6x] linker errors using DSPLIB c67x

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

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,

This fixed my problem:

extern "C" {
#include "DSPF_sp_mat_mul.h"
}

Thanks for the discussions,
Simon
