Please WHERE ARE TI _DSPLINK_init, MSGQ_alloc, MEM_free,_MEM_valloc ... libraries

Please Where are the libraries for  _FXN_F_nop , _GBL_procId _LOG_printf ,   _MEM_free , _MEM_valloc,  _MSGQ_ATTRS,  _MSGQ_alloc,   _MSGQ_close _MSGQ_config, _POOL_config  , _SYS_sprintf,  located. 

I keep getting "unresolved symbol _DSPLINK_init" type errors in code composer 4.0  when I compile, the TI "message" example for dsplink applications.  Does these have to do with assembly?

    These errors show that the build is unable to link DSPLink dsp side libraries like dsplink.lib etc

    I do not have a reference for CCS v4 but I have a link which talks about building DSPLink sample apps for CCS v3.

    See here http://processors.wiki.ti.com/index.php/Building_DSPLink_Applications#Method_3:_Building_a_DSPLink_application_using_a_CCS_project_file

    Hey Deepali,  I have already fixed the error but thanks for the reply.   I used the same website that you mentioned. (click here) . Here is what I did in case anyone else  come

    across the same problem.   Ultimately, I think the main problem was that CCS4.0 was not able to see my *.lib library, like you said. But here is what I did.

    0.)  Made sure dsplink was downloaded properly -  to download OMAP_L138_setupwin32_1_00_00_11.exe  go to

    http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/omap_l138/1_00/latest/index_FDS.html . You will need to enter your password and username

    1.) Went  to the website  http://processors.wiki.ti.com/index.php/Building_DSPLink_Applications#Method_3:_Building_a_DSPLink_application_using_a_CCS_project_file

    2.) On this webpage there is a file named DSPLinkSampleBuild.zip. I downloaded it and unzipped it.  

    3.) On Code Composer Studio 4.0 (CCS 4.0). I imported the DSPLinkSampleBuild.pjt into CCS 4.0 as Legacy CCS3.3 Project - i.e (Project >Import Legacy CCSv3.3 project)

    4.) My intent was to replicate exactly what was done in the DSPLinkSampleBuild, except that I will be using the loop example in ${DSPLink directory}/dsp/src/sample/loop

    5.) I created my on new Project - (File>New>CCS Project) , and named it "PROJECTS".

             5.1. In this project  I ensured that all my predefined variable was included in quotation marks. Previously I was doing this without the quotation marks. 

                      So basically, I right clicked on my project - "PROJECTS". Clicked on  "BUILD PROPERTIES". When you download CCS4.0 it also downloads the C600

                     Compiler and when you create a new CCS 4.0 project it already loads it in build property. Under C600 Compiler, I clicked on "Predefined Symbols", and I

                     inserted on the predefined symbol, based on the values in TI_DSPLINK_DSP0_DEFINES and TI_DSPLINK_DSP_COMMON_DEFINES in  CURRENTCFG.

                     To get CURRENTCFG go to ${DSPLink_directory}\config\BUILD.  If CURRENTCFG is not found, you might need to rebuild your dsplink files - click here to 

                      learn how to build dsplink.   .   

                     So basically, insert this -

           

     

    I hope this helps for anyone that comes across the same errors.

    Thanks again Deepali

             

     

    "PROCID=0";" DA8XXGEM";"DA8XXGEM_INTERFACE=SHMEM_INTERFACE";"PHYINTERFACE=SHMEM_INTERFACE";"DSP_TSK_MODE";

    "MAX_DSPS=1";"MAX_PROCESSORS=2";"ID_GPP=1";"OMAPL138";"PROC_COMPONENT";"POOL_COMPONENT";"NOTIFY_COMPONENT";"MPCS_COMPONENT"; "RINGIO_COMPONENT";"MPLIST_COMPONENT";"MSGQ_COMPONENT";"MSGQ_ZCPY_LINK";"CHNL_COMPONENT";"CHNL_ZCPY_LINK ZCPY_LINK"

    The semi colon specifies a new line .  Make sure you clike on "Apply" when you insert all of this

                    5.2  After this I clicked on the "Include Options" under the C600 Compiler tab on the left.  Then I inserted all the include files based on all the paths specified in

                         the   TI_DSPLINK_DSP0_INC_PATH variable in CURRENTCFG file (${DSPLINK Directory)\config\BUILD)

                   5.3  Then I clicked on "File Search Path" under C600 Linker, and include the following search path  under , 'Add <dir> to library search path( --search_path, -i)

                               ${BIOS dir}\packages\ti\bios\lib

                               ${BIOS dir}\packages\ti\rtdx\lib\c6000

                               ${BIOS dir|\packages\ti\psl\lib

                              ${ccsv4 dir }\tools\compiler\c600\lib

                              ${ccsv4 dir}\tools\compiler\c600

                              ${CG_TOOL_ROOT}/include

     Make sure you click on "APPLY" , then build the project .  

    Ultimately, like I mentioned and like you said the make sure the files libraries can be found in your project -dsplink.lib, dsplinkdata.lib, dsplinkmpcs.lib,dsplinkmplist.lib,dsplinkmsg.lib, dsplinknotify.lib,dsplinkpool.lib, dsplinkringio.lib. This libraries can be found in ${DSPLINK dir}\dsp\BUILD\OMAPL138GEM_0\EXPORT\RELEASE
