    i tried to compile it using debug version.however, when i try to build the testblogcode withinthe cvblobslib, it shows that mfc42d.dll is missing.

    i tried to compile cvblobslib using release version too. but when i try to build the testblog code, it will shows that there are no symbol loaded for the kernel.dll and it will force to break and not able to proceed more.

    can you please help me to understand how can i solve these 2 problems?

    The code Im sharing here is a debug build..

    Freshly compile cvblobslib,
    Open a new project and copy-paste (only) the code.
    Add necessary library files,
    Select debug/release and compile.

    That should work.

    Hello for KingDug
    Comment out the following line:
    #define _SHOW_ERRORS
    in file: BlobLibraryConfiguration.h

    For me everything works just fine after doing that.

    cvblobslibv8.3, with openCV 2.3.1

    have you changed the use of MFC as shared lib in your program ? -> http://goo.gl/2rI8a

    --You also need to link your program to cv.lib highgui.lib etc.. if you have not linked globally..

    It's been a long time but I still have a problem here. Every time I try to debug cvblobslib.lib I have notification like this:
    "unable to start program 'C:\cvblobs\.\Debug\cvblobslib.lib'
    The specified file is an unrecognized or unsupportted binary format"
    Can you help me?
    Thanks
