OpenCV GTK + 2.x错误 [英] OpenCV GTK+2.x error

问题描述

我已按照以下步骤安装OpenCV（）。
在尝试编译一个例子后，我得到这个错误：

I had installed OpenCV following these steps (). After trying to compile one examples,i got this error :

OpenCV Error: Unspecified error (The function is not implemented. Rebuild the library with Windows, GTK+ 2.x or Carbon support. If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script) in cvNamedWindow, file /home/nick/.Apps/opencv/modules/highgui/src/window.cpp, line 516
terminate called after throwing an instance of 'cv::Exception'
  what():  /home/nick/.Apps/opencv/modules/highgui/src/window.cpp:516: error: (-2) The function is not implemented. Rebuild the library with Windows, GTK+ 2.x or Carbon support. If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script in function cvNamedWindow

CMakeLists.txt

CMakeLists.txt

cmake_minimum_required(VERSION 2.8.4)
project(threadTest)

find_package( OpenCV REQUIRED )


set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -Wall -Wextra -pthread")
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY "/home/nick/ClionProjects/threadTest")

set(SOURCE_FILES main.cpp)
add_executable(threadTest ${SOURCE_FILES})
target_link_libraries( threadTest ${OpenCV_LIBS} )

如何解决？

推荐答案

首先检查libgtk2.0-dev是否正确安装。如果您安装了aptitude软件包管理器，请运行以下命令：

First check whether libgtk2.0-dev is installed properly. If you have installed aptitude package manager, run the following:

sudo aptitude search libgtk2.0-dev

它应该返回如下：

i  libgtk2.0-dev              - development files for the GTK+ library 
p  libgtk2.0-dev:i386         - development files for the GTK+ library

您需要再次构建文件。找到您的OpenCV文件夹。创建一个新文件夹并将其命名为release。输入到此文件夹。例如

You need to build the files once again.Locate your OpenCV folder. Create a new folder and name it as release. Enter into this folder. For example

cd /home/user_name/OpenCv
mkdir Release
cd Release

现在使用cmake创建命令如下：

Now build using cmake with following command:

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D WITH_QT=ON -D WITH_GTK=ON -D WITH_OPENGL=ON ..

code> WITH_GTK = ON 。
此步骤后输入命令

Remember to put WITH_GTK=ON during cmake. After this step enter the command,

make
sudo make install

这应该可以解决你的问题。如果libgtk2.0-dev的依赖关系已经破坏，请安装libgtk2.0- dev使用aptitude。

This should resolve your problem.If you have broken dependencies for libgtk2.0-dev, then install a fresh copy of libgtk2.0-dev using aptitude.

sudo aptitude install libgtk2.0-dev
