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.
