GDB Not Responding popup on Ubuntu 24.04.1 LTS after 20sec but debugging works

Sl3dg3 · 1 Feb 2025, 20:40

Hello,

this Qt Creator popup appears after 20 seconds when running my C++17 app with Vulkan rendering and XCB on Ubuntu 24.04.1 LTS:

But the app works fine, rendering works fine, debugging works fine. I can set breakpoints and step through the code etc.

This is my setup:

Ubuntu 24.04.1 LTS 64-bit

Qt Creator 15.0.0
Based on: Qt 6.8.1 (GCC 10.3.1 20210422 (Red Hat 10.3.1-1), x86_64)

GNU gdb (Ubuntu 15.0.50.20240403-0ubuntu1) 15.0.50.20240403-git

g++ (Ubuntu 13.3.0-6ubuntu2~24.04) 13.3.0

Qt 6.8.1 installed (but happens also without Qt which I actually don't need for my app)

Python 3.12.3

Debugger log also shows the timeout:

d[GDB] TIMED OUT WAITING FOR GDB REPLY. COMMANDS STILL IN PROGRESS: "-thread-info", "threadnames 20", "python theDumper.fetchStack({"limit":20,"nativemixed":0,"token":23})"

Scrolling up in the log there are some suspicious lines but not sure if they are related:

eERROR: UNEXPECTED STATE: InferiorRunRequested  WANTED: InferiorStopOk IN /home/qt/work/build/qt-creator/src/plugins/debugger/gdb/gdbengine.cpp:1282
<19importPlainDumpers on
eERROR: UNEXPECTED STATE: InferiorRunRequested  WANTED: InferiorStopOk IN /home/qt/work/build/qt-creator/src/plugins/debugger/gdb/gdbengine.cpp:1330
 Stopped.

Scrolling further up there is also some strange qt5 related output but neither I nor this Qt Creator build is using Qt5:

 Setting up inferior...
<# directory does not exist: /usr/src/debug/qt5base/src/corelib
<# directory does not exist: /usr/src/debug/qt5base/src/gui
<# directory does not exist: /usr/src/debug/qt5base/src/network

Not sure if it matters, application log shows some missing files for some libs:

20:04:55: Debugging /home/<REMOVED FOR PRIVACY REASONS> ...

could not find '.gnu_debugaltlink' file for /lib/x86_64-linux-gnu/libcap.so.2
20:05:28: Debugging of /home/<REMOVED FOR PRIVACY REASONS> has finished with exit code 0.

Anyone knows why this happens although I can run and debug the program just fine?

Will try to post the full debugger log afterwards because I cannot post it without exceeding the limit here.

Help is very appreciated!

Full debugger log (just some minor stuff like paths removed for privacy reasons):

wNote: This log contains possibly confidential information about your machine, environment variables, in-memory data of the processes you are debugging, and more. It is never transferred over the internet by Qt Creator, and only stored to disk if you manually use the respective option from the context menu, or through mechanisms that are not under the control of Qt Creator's Debugger plugin, for instance in swap files, or other plugins you might use.

there is no such timeout so it must be something that Qt Creator IDE is doing?

@Sl3dg3: Do you have QML debugging enabled in (left mode bar) Projects > Kit > Run > Debugger Settings?

For me disabling that gave a great GDB speedup for some projects.

Thank you so much for pointing me at these settings!
Disabling the QML debugging had no effect BUT unchecking "Run in terminal" solved the problem!
