crosscompile OpenCV 2.4.10

edit

Hey, i want to install the latest openCV 2.4.10 for an ARM Cortex. Ive installed the crosstool-ng and build the

arm-unknown-linux-gnueabi

toolchain with no problems. After this, i downloaded the latest openCV zip file and extract it. Then changed the following lines

platforms/linux/arm-gnueabi.toolchain.cmake

from :

set(GCC_COMPILER_VERSION "4.6" CACHE STRING "GCC Compiler version")

    set(FLOAT_ABI_SUFFIX "")

if (NOT SOFTFP)
  set(FLOAT_ABI_SUFFIX "hf")
endif()

set(CMAKE_C_COMPILER    arm-linux-gnueabi${FLOAT_ABI_SUFFIX}-gcc-${GCC_COMPILER_VERSION})
set(CMAKE_CXX_COMPILER  arm-linux-gnueabi${FLOAT_ABI_SUFFIX}-g++-${GCC_COMPILER_VERSION})
set(ARM_LINUX_SYSROOT /usr/arm-linux-gnueabi${FLOAT_ABI_SUFFIX} CACHE PATH "ARM cross compilation system root")

to

set(GCC_COMPILER_VERSION "4.9.1" CACHE STRING "GCC Compiler version")
    set(FLOAT_ABI_SUFFIX "")

    if (NOT SOFTFP)
      set(FLOAT_ABI_SUFFIX "hf")
endif()

set(CMAKE_C_COMPILER    /home/x-tools/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi-gcc-4.9.1)
set(CMAKE_CXX_COMPILER  /home/x-tools/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi-g++)
set(ARM_LINUX_SYSROOT   /home/x-tools/arm-unknown-linux-gnueabi/ CACHE PATH "ARM cross compilation system root")



cmake -DCMAKE_TOOLCHAIN_FILE=~/workspace/cross/opencv/opencv-2.4.10/platforms/linux/arm-gnueabi.toolchain.cmake ~/workspace/cross/opencv/opencv-2.4.10/

all works fine, but now, after the

make

[ 80%] Building CXX object modules/ocl/CMakeFiles/opencv_perf_ocl.dir/perf/perf_hog.cpp.o

he still hangs at 80% for over one hour.
