Question

我正在远程无头RHEL7.2 VM上运行Qt creator 4.7.1，我使用Windows上的mobaXterm的Xserver连接到该端口，并在VM中导出DISPLAY。 IDE可以正常启动（与其他任何xclient一样），但是当我尝试调试当前崩溃的应用程序时，它不会加载调试符号。这是堆栈跟踪：

仅可访问框架13和14，其他框架则显示为灰色。我已经使用debuginfo-install qt安装了所有与调试相关的程序包，并且与sqlite-debuginfo这样的辅助程序包一起也安装了qt-debuginfo。

IDE中的调试消息如下：

09:48:58: Debugging starts
QML debugging is enabled. Only use this in a safe environment.
QFactoryLoader::QFactoryLoader() checking directory path "/path/to/my/src" ...
QFactoryLoader::QFactoryLoader() looking at "/path/to/my/src/libqeglfs.so"
Found metadata in lib /path/to/my/src/libqeglfs.so, metadata=
{
    "IID": "org.qt-project.Qt.QPA.QPlatformIntegrationFactoryInterface.5.3",
    "MetaData": {
        "Keys": [
            "eglfs"
        ]
    },
    "className": "QEglFSIntegrationPlugin",
    "debug": false,
    "version": 329472
}
Got keys from plugin meta data ("eglfs")

然后继续加载linuxfb，minimal，minimalegl，offscreen，vnc，webgl和xcb。但是，它可能无法正确加载xcb，就像

一样

Got keys from plugin meta data ("xcb")
loaded library "/path/to/my/src/libqxcb.so"
RTTI symbol not found for class 'QApplication'
RTTI symbol not found for class 'QApplication'
RTTI symbol not found for class 'QApplication'
...

我相信我拥有所有相关的软件包，即libxcb-debuginfo，xcb-util-debuginfo，xcb-util-image-debuginfo，xcb-util-keysyms-debuginfo，xcb-util-renderutil-debuginfo，但也许我错过了一些东西吗？ / p>
