    I fixed this problems.

    I changed the gcc version in codeblocks 12.11

    I download gcc 4.6.1 to the /Program Files/codeblocks/MinGW

    then the opencv program till not working because of missing libgcc_s_dw2-1.dll

    google the libgcc_s_dw2-1.dll and put it into /Program Files/codeblocks/MinGW/bin

    success!

    and maybe this link:OpenCV program cannot run because of missing "libgcc_s_dw2-1.dll" in Code::Block
    may help this kind of problem.
