Errors

• /usr/local/include/c++/6.2.0/cstdlib:75:25: fatal error: stdlib.h: No such file or directory

  -D ENABLE_PRECOMPILED_HEADERS=OFF

• nvcc fatal : Unsupported gpu architecture ‘compute_11’
  CMake Error at cuda_compile_generated_matrix_operations.cu.o.cmake:206

  -D CUDA_GENERATION=Kepler
  (When using cmake to do configurations, set the option CUDA_GENERATION to specific your GPU architecture.)

Check Informations

• 查看opencv版本

pkg-config --modversion opencv

• 查看opencv包含目录

pkg-config --cflags opencv

• 查看opencv库目录

pkg-config --libs opencv

Using

Compilation

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

Multiple OpenCV

Installation

Ubuntu 15.04 Opencv 安装（多版本并存）

Using

Using CMake

在opencv编译好后，所在目录中一般会有一个叫OpenCVConfig.cmake的文件，这个文件指定了CMake要去哪里找OpenCV，设置OpenCV_DIR为包含OpenCVConfig.cmake的目录(可设置CMAKE_MODULE_PATH)，如在C++工程CMakeLists.txt中添加

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

因此，使用哪个版本的Opencv，只要找到对应的OpenCVConfig.cmake文件，并且将其路径添加到工程的CMakeLists.txt中即可。

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：

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：

COMMON  += -DOPENCV
CFLAGS  += -DOPENCV
LDFLAGS += `pkg-config --libs opencv-2.4.12`
COMMON  += `pkg-config --cflags opencv-2.4.12`

Uninstall

sudo make uninstall
or
#install-mainfest.txt包含了安装文件的路径
sudo cat install-manifest.txt | sudo xargs rm
