problems cross compiling OpenCV with FFMpeg for ARM Linux

Hello all,

I am trying to cross compile OpenCV with FFMPEG for ARM Linux, but I get some errors.

First, I have cross compiled FFMPEG using these flags:

./configure --enable-cross-compile --cross-prefix=arm-linux-gnueabi- --cc=arm-linux-gnueabi-gcc --cxx=arm-linux-gnueabi-g++ --arch=arm --target-os=linux --disable-armv5te --disable-armv6 --disable-armv6t2 --enable-libopencv --enable-pic prefix=/home/mypath/ffmpeg_binARM

Then, I have modified "OpenCVFindLibsVideo.cmake" file In order to "see" the ffmpeg libraries:

--- FFMPEG ---

ocv_clear_vars(HAVE_FFMPEG HAVE_FFMPEG_CODEC HAVE_FFMPEG_FORMAT HAVE_FFMPEG_UTIL HAVE_FFMPEG_SWSCALE HAVE_GENTOO_FFMPEG HAVE_FFMPEG_FFMPEG) if(WITH_FFMPEG) if(WIN32) include("${OpenCV_SOURCE_DIR}/3rdparty/ffmpeg/ffmpeg_version.cmake") elseif(UNIX)

set(FFMPEG_INCLUDE_DIR /home/mypath/ffmpeg_binARM/include)
set(FFMPEG_LIB_DIR /home/mypath/ffmpeg_binARM/lib)

set(HIGHGUI_LIBRARIES ${HIGHGUI_LIBRARIES} "${FFMPEG_LIB_DIR}/libavcodec.a"
      "${FFMPEG_LIB_DIR}/libavformat.a" "${FFMPEG_LIB_DIR}/libavutil.a"
      "${FFMPEG_LIB_DIR}/libswscale.a")
set(HAVE_GENTOO_FFMPEG TRUE)
if(EXISTS "${FFMPEG_LIB_DIR}/libavcodec.a")
    set(HAVE_FFMPEG_CODEC 1)
    set(ALIASOF_libavcodec_VERSION "Unknown")
    if(EXISTS "${FFMPEG_LIB_DIR}/libavformat.a")
      set(HAVE_FFMPEG_FORMAT 1)
      set(ALIASOF_libavformat_VERSION "Unknown")
      if(EXISTS "${FFMPEG_LIB_DIR}/libavutil.a")
        set(HAVE_FFMPEG_UTIL 1)
        set(ALIASOF_libavutil_VERSION "Unknown")
        if(EXISTS "${FFMPEG_LIB_DIR}/libswscale.a")
          set(HAVE_FFMPEG_SWSCALE 1)
          set(ALIASOF_libswscale_VERSION "Unknown")
          set(HAVE_FFMPEG 1)
        endif()
      endif()
    endif()
  endif()

ocv_include_directories(${FFMPEG_INCLUDE_DIR})

endif()

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

Finally, I have tried to cross compile OpenCV using this help: http://docs.opencv.org/doc/tutorials/introduction/crosscompilation/arm_crosscompile_with_cmake.html

cd ~/opencv/platforms/linux mkdir -p Build_ARM cd Build_ARM

cmake -DSOFTFP=ON -DCMAKE_TOOLCHAIN_FILE=../arm-gnueabi.toolchain.cmake ../../..

...and I get these errors when I do "make". Can anyone help me????
