Question

我再ubuntu下安装OpenCV是编译的时候没有提示错误，但是在运行程序的时候提示：

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/lxj/OpenCV-2.3.1/modules/highgui/src/window.cpp, line 275
terminate called after throwing an instance of 'cv::Exception'
what(): /home/lxj/OpenCV-2.3.1/modules/highgui/src/window.cpp:275: 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
，我百度过了，也谷歌过了，但是就没有确切的解决方法，我确定有装过ibgtk2.0-dev and pkg-config，也重新编译过 ，结果还是一样，希望能得到大侠的指点。

Answer 1

简单的解释就是你的GTK+2.x要先于OpenCV安装,所以它给的解决方法是You should remove the current installation of opencv from your system; rebuild your opencv lib after installing gtk dev lib in the correct path; and reinstall the compiled opencv lib.

Answer 2

你的Linux是不是没有GUI
