Check Informations

• 檢視opencv版本

pkg-config --modversion opencv

• 檢視opencv包含目錄

pkg-config --cflags opencv

• 檢視opencv庫目錄

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 安裝（多版本並存）

Using

Using CMake

在opencv編譯好後，所在目錄中一般會有一個叫OpenCVConfig.cmake的檔案，這個檔案指定了CMake要去哪裡找OpenCV，設定OpenCV_DIR為包含OpenCVConfig.cmake的目錄(可設定CMAKE_MODULE_PATH)，如在C++工程CMakeLists.txt中新增

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

因此，使用哪個版本的Opencv，只要找到對應的OpenCVConfig.cmake檔案，並且將其路徑新增到工程的CMakeLists.txt中即可。

Using Makefile

將opencv-3.1.0.pc和opencv-2.4.12.pc拷貝到/usr/lib/pkgconfig目錄(可設定PKG_CONFIG_PATH)下，
使用opencv-3.1.0時，Makefile中為：

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時，Makefile中為：

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包含了安裝檔案的路徑
sudo cat install-manifest.txt | sudo xargs rm
