Hello,

Why do we want to create a vanilla Empty Project with a dummy main.c and not an Empty RTSC project?

I created another new Empty Project as you suggested and called it "g711aenc2".  I followed your instructions and created an "alg.h" header file and placed it in the same subdirectory as the other ..\ti\xdais header files. I also commented out the reference to  "#include <_alg.h>"  in alg_create.c.   When I compiled the project I get a slew of new error messages and warnings:

By the way, what are you using for the linker command file?  I am using the g711_c6455_elf.cmd that I found under ..\ti\sdo\codecs\g711aenc\app\client\build of the original unzipped package.

Joseph,

Have you linked in the g711aenc library, and have you changed the compiler options to build ELF format?

I didn't use the g711_c6455_elf.cmd file, but I think you could, and you could adjust the memory for your platform.  I think I just got some default memory map.

Best regards,

    Janet

Hello,

Yes, I have g711aenc_tii_elf.I64P in the same directory in the project as g711Encodermain.c, and yes I have changed the output format to eabi (ELF).

Upon closer examination of the warning messages, the alg_create.c file is not seeing a header file for "_ALG_allocMemory(memTab, n)" and "_ALG_freeMemory(memTab, n)".

Upoon closer examination of the warning messages for g711Encodermain.c, the compiler/linker doesn't know how to resolve "exit(0)'.  Likewise, it also doesn't know how to resolve the following in g711Encodermain.c: between lines 203..210:

      if ((handle =  (ISPHENC1_Handle) ALG_create (
                                      (IALG_Fxns *) &G711AENC_TII_IG711AENC,
                                      (IALG_Handle) NULL,
                                      (IALG_Params *) &params)) == NULL)
      {
        printf("Failed to Create Instance... Exiting for this configuration..\n");
        exit(1);
      }

ALG_create() and ALG_delete() were defined in t alg.h, which is the missing file we needed to create. I put that file under c:\ti\xdais_7_21_01_05_eng\packages\ti\xdais where ialg.h and xdas.h are located.

Finally I created my own g711_c674x.cmd, which has the same contents as g711_c6455_elf.cmd, but with the memory address map for a C674x chip. I still get all the errors that I reported yesterday.

Attached is a zipped copy of my current project:

7181.g711aenc2.zip

Joseph,

I was able to build your project after adding a few directories to the the include search path, and the encoder library and path to the project.  Here is a list of what I did to get it to build (note that you have already done some of these steps, but since I have xdctools, xdais, etc in different directories, I had to add my directories to the projects include and library search paths.

I imported the project from the zip file you posted, and tried to build.

First error:

and library search path:  "I:\jeh\docs\support\g711\ti\sdo\codecs\g711aenc\lib"   to project.

After that, I was able to build the .out (still plenty of warnings, though).  The _ALG_allocMemory() and _ALG_freeMemory() functions must have been defined in the missing _alg.h file.

Are these the errors you were also seeing?

Best regards,

    Janet

Hello,

I haven't seen the first five compilation errors that you listed in your posting. I believe that they were caused by difference in our tool chain paths, which in turn affect our respective include paths, i.e.

"${CG_TOOL_ROOT}/include"
"C:/ti/xdctools_3_22_03_41/packages"
"C:/ti/xdctools_3_22_03_41/packages/xdc"
"C:/ti/xdais_7_21_01_05_eng/packages/ti/xdais"
"C:\Program Files (x86)\c64xplus_g711_2_00_00_000_production\c64xplus_g711adec_2_00_00_000_production\ti\sdo\codecs\g711adec\app\Inc"

As an aside, I did a search on my hard drive and I located two different versions of "alg.h" and "_alg.h".  At some point when I was installing software for my OMAP-L137 board, I downloaded the C674x_dsp_1_00_00_11 archive, which included  subdirectories for "framework_components_2_23_01"  and "codec_engine_2_23_01". Each subdirectory  had it's own version of "alg.h" and "_alg.h".  I copied the version of these files from "framework_components_2_23_01" and placed them under  "C:/ti/xdais_7_21_01_05_eng/packages/ti/xdais".  I restored the reference to "#include <_alg.h>" in "alg_create.c" and recompiled my project. That resolved the problem with _ALG_allocMemory() and _ALG_freeMemory() functions, but still left me with the other errors that I reported earlier.

Another interesting thing to point out is that all the functions found in  "alg.h"  under   "codec_engine_2_23_01"  have an additional function parameter "groupId" of type "Int",  i.e.

     extern ALG_Handle ALG_create(IALG_Fxns *fxns, IALG_Handle p, IALG_Params *prms);

versus

     extern ALG_Handle ALG_create(Int groupId, IALG_Fxns *fxns, IALG_Handle p, IALG_Params *prms);

Over the past 3 or 4 years we have seen the XDM interface evolve from version 0.9 to version 1.0 to version 1.1. For some reason which I can not fathom, the header files alg.h and _alg.h have never been  located under the  "ti\xdais_<version>\packages\ti\xdias" subdirectory where other files such as "ialg.h" are stored.  As a software developer trying to use TI's codec library or volib library, I don't see how we can ever get these libraries to compile and link if we don't have the correct header files installed under the correct tool chain.

Joseph,

The header files alg.h and _alg.h are not part of the xdais product.  The G711 encoder test has its own alg.h and _alg.h, which should have been included with the test, but are missing.  These header files are not the same as the ones used in framework components or codec engine.  The contents of the alg.h that I posted earlier is what you need to build the test. It's probably better to place this alg.h in the test directory, rather than under xdais, since it is specific to the test.

Are you still getting the linker error, unresolved symbol G711AENC_TII_IG711AENC, or is there some other error?

Best regards,

    Janet

Hello,

If I don't use the "_alg.h" obtained from somewhere else, then we to create one to resolve the problem with the missing _ALG_allocMemory() and _ALG_freeMemory() functions.

The following are the error and warning messages that I am still seeing:

Joseph,

Did you add the g711 library to your project?  The zipped up project that you posted yesterday did not have that library.  You need to add the library and the search path to the project link options.  In CCS, open your project Build Options, and then go to:

    Build -> C6000 Linker -> File Search Path

This is what I did:

Sorry, but I don't know why my screen shot wasn't uploaded.  It showed both the library in the upper box, and the path to it in the lower box.

Best regards,

    Janet

Hello,

After adding the file search path to the project to locate g711aenc_tii_elf.l64P, it resolved the missing symbol G711AENC_TII_IG711AENC.  There are no further errors preventing g711aenc3.out from being produced, but there still are 23 warning message that I reported earlier.

I would like to try and run the test application on the TI software simulator, but the question next becomes which one?  Under

     General -> Build Options ->  Variant:

I have "Generic C674x Device" selected.  Should it be "Generic C64x+ Device" instead to run the codec library?

Likewise under

    General -> Build Options -> Advanced Settings -> Rutime support library:

I have "<automatic>"  choice selected.  When I looked at g711aenc2.map, the  "rts6740_elf.lib"  was chosen as the runtime support library.  Should I explicitly select "rts64plus_elf.lib"  instead?

Finally, under

     Project -> New -> Target  -> Texas Instrument Simulator

I selected "C674x CPU Cycle Accurate SImulator, Little Endian".  Should it be "C64x+ CPU Cycle Accurate Simulator, Little Endian"?

Joseph,

I could create CCSv5 projects for G711, based on version 2_00_00 downloaded from TI website, and I could build and run them on C6747 Device simulator for the sample test vector available.

Please find attached the archive for your reference. The project files are available @ \app\Client\Build\Encoder (Decoder).

I have used the following tools set and Build Variables to set, you may need to update these Build Variables if you are using dufferent tool set.

BIOS_INSTALL_DIR=C:\CCSV5\bios_6_31_00_18

XDCROOT=C:\CCSV5\xdctools_3_20_08_88

FRMWORKROOT=C:\CCSV5\framework_components_3_20_02_29

To change these variables, Import the CCS project, Right click on the project and Select "Build Options". Select "Build" Tab. You can find the above variables under "Build Variables". Click Edit and Modify according to your PATHs. If you have the above tools installed at C:\CCSv5, no need to make any changes, the projects should build as is and work for you.

Let me know if you have any difficulties or questions.

Thanks,

can u suggest any solution?

Hello lenin,

I am not a TI employee, but I can offer a few suggestions.

1.  When you created your project, did you specify that the output format of the build is "eabi (ELF)" and not "Legacy COFF" format? The G.711 library that you are linking with is ELF format.

2. What are you using for your linker command file?  The g711_c6455_elf.cmd  file that is packaged with the test application might not match the memory map of your target platform.  I had to create my own .cmd file to match the target DSP chip on my EVM board.

Hi Joseph,

Thanks for the reply.

I have specified the output format as "eabi" by seeing the earlier posts.

The library i am using is "g711aenc_tii_elf.l64p".

I tried to make my own cmd file but still i find same errors.

[C674X_0] Testing G.711 Encoder
[C674X_0]
[C674X_0] Error in opening input file
[C674X_0] All input Files processed

when i tried to run the program i get the following error:

No source available for "C$$EXIT() at C:\Documents and Settings\lenin\workspace_v5_2\g711a_encoder\Debug\g711a_encoder.out:{3} 0x8000bda0{4}"
