    # 查看opencv包含目录
    pkg-config --cflags opencv

    # 查看opencv库目录
    pkg-config --libs opencv

    # When using cmake to do configurations,
    # set the option CUDA_GENERATION to specific your GPU architecture

Usage

using g++

1
g++ `pkg-config opencv --cflags` test.cpp -o test `pkg-config opencv --libs`

using CMake

1
2
3
set(OpenCV_DIR "/home/ubuntu/src/opencv-3.1.0/build")
find_package( OpenCV REQUIRED )
include_directories( ${OpenCV_INCLUDE_DIRS} )

using Makefile

将opencv-3.1.0.pc和opencv-2.4.12.pc拷贝到/usr/lib/pkgconfig目录(可设置PKG_CONFIG_PATH)下， 使用opencv-3.1.0时，Makefile中为：

1
2
3
4
COMMON  += -DOPENCV
CFLAGS  += -DOPENCV
LDFLAGS += `pkg-config --libs opencv-3.1.0`
COMMON  += `pkg-config --cflags opencv-3.1.0`

使用opencv-2.4.12时，Makefile中为：

1
2
3
4
COMMON  += -DOPENCV
CFLAGS  += -DOPENCV
LDFLAGS += `pkg-config --libs opencv-2.4.12`
COMMON  += `pkg-config --cflags opencv-2.4.12`

  • to compile for Android with ANDROID_STL=c++_static(shared), use Android NDK own CMake toolchain file and clang(ref: https://github.com/opencv/opencv/issues/8742#issuecomment-385553011)

    -DCMAKE_TOOLCHAIN_FILE="${ANDROID_NDK}/build/cmake/android.toolchain.cmake" \
    -DANDROID_TOOLCHAIN=clang \
    -DANDROID_STL=c++_static \

  • with platforms/android/build_sdk.py

    python build_sdk.py \
      --ndk_path $ANDROID_NDK \
