function declared implicitly

Hi, guys.
Prompt, please, as it can be. In the folder inclule file prototypes lies, the path is correct, in project->build options->preprocessor->include search path, too, is all. Previously, at the old project  it works. Why is this possible?
Thanks.

    I'm not sure I understand what your question is. Would you please reiterate?

    Dear Tim,

    I want to use the function VLIB_extractLumaFromUYUV_i() in my program. I included the header file "VLIB_prototypes.h" and "vlib.l64p" but can't build the project. Compiler writes "function declared implicitly". I can't understand why? As I think the compiler doesn't "see" the header file. What should I do?

    Thanks,

    Igor.

    It may be a header file issue. I don't see the function: VLIB_extractLumaFromUYUV_i in the User's Guide. What I see is: VLIB_extractLumaFromUYUV. Not the _i at the end is missing. The name in the document is also consistent with how the other APIs are defined.
    I recommend modifying the header file by changing the API name to VLIB_extractLumaFromUYUV and see if you still get the error

    Dear Gagan!

    You are absolutely right. This is my child mistake.
    Thank you very much.

    Hi everyone,

    I can't understand:

    There is in example file VLIB_testExtractLumaFromUYUV :

    -----------------------------------------------------------------------------------------------

    VLIB_extractLumaFromUYUV_i(YUV422Data, // input YUV422 image 
                                                         ^^^
    8, // width of input image
    8, // pitch of input image
    4, // height of input image
    extractedLumaData); // luma-only output image

    ---------------------------------------------------------------------------------------------

    But in file VLIB_prototypes.h there is  without   _i   ( VLIB_extractLumaFromUYUV_i  vs. VLIB_extractLumaFromUYUV):  

    ---------------------------------------------------------------------------------

    int VLIB_extractLumaFromUYUV
    (
    unsigned char* restrict pInUYVY,
    unsigned short inCols,
    unsigned short inPitch,
    unsigned short inRows,
    unsigned char* restrict pOutY
    );

    ---------------------------------------------------------------------------------

    And example works o'k.

    But if I use function with  "..._i "  I get an error " function declared implcitly.

    If I use function without "..._i " I get an error  after "rebuild all "   - " relocation from function to symbol  "_VLIB_extractLumaFromUYUV" overflowed ;

    Please, explain, what is wrong and what is right.

    Thanks a lot,
    Igor.

    Hello Igor,

    VLIB_extractLumaFromUYUV (without  _i ) is the right way to use this API.

    In the VLIB_prototypes, there was an error in this definition. Please remove the _i there and ignore the _i .

    If you had done this change, the API should work.

    You mentioned that the example works ok. Did you run the test project VLIB_testExamples.pjt and checked whether this function passed the test ?

    If it is possible to send the source file where u r using this function, I can try debugging.

    Regards

    Senthil

    Hello, Senthil.

    Yes, of couse it it possible. More to say it is the most important thing at this moment for me.

    I don't know where to send files. My email   ars-sec@mail.ru .

    Another thing - I tested with both (_i) in source file and VLIB_prototypes and works properly. Magic... Without (_i) doesn't work.

    Thanks, Senthil.

    I am waiting your replay,

    Warm regards,

    Igor.
