CCS/TDA2PXEVM: Getting linking issues in CCS static library creation

Megha Ambekar

Part Number: TDA2PXEVM

Tool/software: Code Composer Studio

Hi,

I am using Code composer studio 7.4.0. for creating static library of C / CPP files. This static library I want to use in vision sdk plugin.

I'm able to create static lib and use successfully in vision sdk when library code doesn't contain vision sdk functions such as Utils_memAlloc, Utils_memFree, UTILS_assert, Utils_getCurGlobalTimeInMsec() etc.

But when I include vision sdk functions in library code, I get compilation error saying "function undefined". My library project location and visionsdk folder are different. I have included vision sdk folder path to ccs static library project in "Properties->Build->C6000 Compiler->Include Options", now I'm not getting compilation error but now I'm getting linking issues in .obj files.

Please suggest how to resolve this issue ?

    Hello,
    The linker errors are likely a missing dependent object file.

    I will move this post to the device forums. The experts there are most familiar with the SDK and can help you further.

    Thanks

    Hi,

    Please try to build using makefile based build system as CCS based build is not supported by TI for VSDK.

    Hi Anuj,

    Thanks for the reply.

    I tried creating makefile based build system project but I did not find a way to create static lib of existing source code.

    Can you please guide me in creating static library of algorithm (contains vision sdk functions ) that will again be used in vision sdk using makefile based build system?

    Regards,

    Megha

    Hi,

    In VSDK we build a lot of static libraries using our makefiles.
    You just need to take a reference of any library.
    Please go through the below doc
    vision_sdk\docs\FeatureSpecificUserGuides\VisionSDK_UserGuide_BuildSystem.pdf

    Hi,
    I'm able to use created static library in vision sdk. and its giving proper output as well.

    But when I used "Vps_printf" , "Utils_memAlloc" etc functions in my source code( code using which static lib needs to be created) , I'm getting following linking issues in creating static library in ccs and library is not getting created:

    gmake: *** [source/fisheye_Image.obj] Error 1 C/C++ Problem
    gmake: Target 'all' not remade because of errors. C/C++ Problem

    I have included visionsdk folder path in Include Options.

    What needs to be done in order to resolve these linking issues?

    Regards,
    Megha

    Hi,

    If you are getting these linking error that means you are not linking with utils_common lib.
    Please make sure you are linking this library.
