@ChenRuiwei can you confirm this is working for you? |
|
Yes, although GDB has reached version 16.2, the problem still persists. I had been using using |
|
I'm still unable to reproduce this issue... it's not clear to me if the culprit is GDB, the Python version embedded by it, or both. I tried with several Debian and Ubuntu versions, with no luck. For example, tab completion works here: |
|
It seems everything is fine as long as nobody imports |
|
This is the current environment I'm working with. I guess that Python needs to be at least version 3.13. I will try to create a Dockerfile to reproduce the issue. |
|
Tried with both:
In both cases, tab completion works properly, and in both cases manually importing |
|
I'm trying with the following and tab completion works properly. FROM archlinux
RUN pacman --noconfirm -Sy gdb wget
RUN wget -P ~ https://github.com/cyrus-and/gdb-dashboard/raw/master/.gdbinit |
|
Try |
|
Do you have a reproducible way of fetching this combo? E.g., a particular version of Arch or something? |
|
install |
|
Things goes weird now. I can no not reproduce this issue in Docker, even though I've tried different versions of GDB and Python...... |
|
You can modify the official fix to debug if you're importing |
Good idea! I output the traceback into in a file when the import error raises. |
|
So it's, at least, Pygments that requires |
|
Pygments is installed by pacman. |
|
I have reproduced the issue in Docker! After I installed all the python packages I have been installed in my host computer in Docker environment, the issue appears. |
|
Can you share the Dockerfile if you have one? |
|
May be this would be OK, I have'nt tested it yet in one Dockerfile though, the network is quite unstable that I can not build it quickly. |
|
After checking the backtrace again, it is |
|
Phew, so it seems it's both:
I can automatically reproduce this with: FROM debian:sid
ARG DEBIAN_FRONTEND=noninteractive
RUN apt update
RUN apt --yes install gdb wget python3-pip vim
RUN wget -P ~ https://github.com/cyrus-and/gdb-dashboard/raw/master/.gdbinit
RUN python3 -m pip install --break-system-packages pygments==2.19.1
RUN printf '#include <stdio.h>\nint main() {printf("asd");}' >main.c
RUN gcc -g main.c
RUN apt --yes install ipython3
ENTRYPOINT ["gdb", "-ex", "start", "a.out"] |

Thank you @neurocyte, but I like @ChenRuiwei's solution better. |
