c++ - cvNamedWindow - 功能未实现，无法启动 LibHand

Question

我想使用 LibHand 手势库，但我无法在 Ubuntu 13.10 上启动它。

我已经成功编译了它(在克服了与链接器相关的几个问题之后)，但是当运行 pose_designer 时，OpenCV 库记录未实现 GUI 支持功能，指示我安装 libgtk2.0-dev 和 pkg-config .但是，在安装这些包并重建 OpenCV 库后，问题仍然存在。受到具有类似 OpenCV 问题 (OpenCV error: the function is not implemented) 的人的 SO 帖子的启发，我转向了 libqt。不幸的是，问题仍然存在。

日志文件的摘录附在下面。出现此错误的原因可能是什么？

WARNING: the mesh 'hand.mesh' includes vertices with more than 4 bone
  assignments. The lowest weighted assignments beyond this limit have been
  removed, so your animation may look slightly different. To eliminate this,
  reduce the number of bone assignments per vertex on your mesh to 4.

Answer 1

好吧，你必须回去重建 opencv(highgui 模块)。

运行 cmake(或 cmake-gui)，并调整设置，直到它确认 gui 支持:

  GUI: 
    QT:                          NO
    Win32 UI:                    YES
    OpenGL support:              NO
    VTK support:                 NO

(好吧，这是为了胜利，但您将拥有一个应该处于“开启”状态的 GTK 条目)
