Ogre3d RestoreConfig 导致应用程序在 Ubuntu 上挂起
使用 Ogre3D、CEGUI、OIS 为 Ubuntu 构建应用程序，现在所有内容都按预期编译和运行。运行基本应用程序后，我决定现在构建一个自定义配置文件，我可以存储图形设置（即分辨率、全屏等）以及我在应用程序中需要的其他可配置设置。
作为起点，我从每次启动时调用 mRoot->showConfigDialog() 更改为：
if(!mRoot->restoreConfig())
mRoot->showConfigDialog();
这是为了从存在的“ogre.cfg”文件中恢复配置，所以它做到了，但要加载天空盒纹理第一个场景创建后就坐在那里什么也不做。
因为这不是我想要的，所以我尝试手动设置，例如：
RenderSystem *rs = mRoot->getRenderSystemByName("OpenGL Rendering Subsystem");
mRoot->setRenderSystem(rs);
rs->setConfigOption("Full Screen","No");
rs->setConfigOption("Video Mode","1024 x 768");
这些与我之前在 showConfigDialog() 函数中使用的“ogre.cfg”中的设置相匹配。然而，我在手动配置中遇到了同样的问题，在加载天空盒纹理时它就停止了。
我无法弄清楚为什么这些更改对应用程序的运行方式有任何影响，并且由于 OIS 获取输入并将鼠标锁定到屏幕，我在尝试使用 gdb 调试它时遇到了麻烦。
Building an app for Ubuntu using Ogre3D, CEGUI, OIS which is now all compiling and running as expected. Having got the basic app running I decided to now build a custom config file which I can store both graphics settings (ie. resolution, fullscreen, etc) as well as other configurable settings I will need in the app down the track.
As a starting point I changed from calling mRoot->showConfigDialog() at each startup to :
if(!mRoot->restoreConfig())
mRoot->showConfigDialog();
this was meant to restore the config from the 'ogre.cfg' file which exists and so it did, but got to loading a skybox texture on the first scene create and just sat there doing nothing.
Since that wasn't what I wanted anyway I tried setting things up manually like :
RenderSystem *rs = mRoot->getRenderSystemByName("OpenGL Rendering Subsystem");
mRoot->setRenderSystem(rs);
rs->setConfigOption("Full Screen","No");
rs->setConfigOption("Video Mode","1024 x 768");
Those matched the settings from 'ogre.cfg' that I was using prior from the showConfigDialog() function. I got the same issue with this manual configuration however, while loading the skybox textures it just stops.
I can't work out why these changes have any bearing at all on how the app runs and since OIS grabs the input and locks the mouse to the screen I am having trouble trying to debug it with gdb.

关于鼠标锁定，您可以在另一个显示器上运行 gdb。它可以是同一台计算机上的显示器（包括诸如 Xephyr 等创建虚拟显示嵌套在当前显示中，或者只是不同显示上的第二个会话 - 如果您有一个工作的 .xinitrc 一次运行两个或三个 X 会话很简单），或者它可以位于网络上的另一台计算机上（即通过 ssh -X）。
Regarding the mouse locking, you can run gdb on another display. It can either be a display on the same computer (including options like Xephyr that create virtual displays nested in the current display, or just a second session on a different display - if you have a working .xinitrc running two or three X sessions at a time is simple), or it can be on another machine on your network (ie. via ssh -X).
