Building

Requirements:

• CMake
• g++ or clang
• make
• OpenCV 2.4+

Change to the build/ directory and run

cmake ..
make

Cross compiling on Ubuntu 14.04

• Install cmake
• Install g++-4.7-arm-linux-gnueabihf
• Install gcc-4.7-arm-linux-gnueabihf

Building opencv

Follow the instruction for building opencv here

Notes:

• Replace compiler version 4.6 in ../platforms/linux/arm-gnueabi.toolchain.cmake with 4.7 so that it bilds with the latest ubuntu stuff

I compiled OpenCV with

cmake -DCMAKE_TOOLCHAIN_FILE=../platforms/linux/arm-gnueabi.toolchain.cmake -DBUILD_opencv_superres=OFF -DCMAKE_INSTALL_PREFIX=/home/lucas/pj2/local/ ..

Building things

In build/ run:

$ cmake -DCMAKE_TOOLCHAIN_FILE=../ArmToolchain.cmake -DOpenCV_DIR=/home/lucas/pj2/local/share/OpenCV  ..
$ make
