Crashes on start on OS Gentoo stable about sniffnet HOT 9 CLOSED

Hello GyulyVGC,

thanks a lot for your help, now it works.

I think the reason for the crash was that vulkan was installed, but not with support for X. I think wgpu has only detected the vulkan driver but not that it doesn't work so it hasn't used OpenGL. After adding "media-libs/vulkan-loader X" to my use flags it starts and works. For the start the XDG_RUNTIME_DIR doesn't matter.

Try with

echo "XDG_RUNTIME_DIR=/run/user/<YOURID>" >> ~/.pam_environment

where <YOURID> is the output of id -u

Hello GyulyVGC,

thank you very much for your help.

I've tried:

% sudo sh -c "id -u; echo "XDG_RUNTIME_DIR=/run/user/0"; /home/myuser/.cargo/bin/sniffnet"
0
XDG_RUNTIME_DIR=/run/user/0
error: XDG_RUNTIME_DIR is invalid or not set in the environment.
thread 'main' panicked at 'called `Option::unwrap()` on a `None` value', /home/myuser/.cargo/registry/src/github.com-1ecc6299db9ec823/wgpu-core-0.12.2/src/hub.rs:960:9
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
% cat ~/.pam_environment
XDG_RUNTIME_DIR=/run/user/0

I also tried to set the uid to 1000 as this is my user without sudo, but the result is the same. I've also tried to set the .pam_environment to /root/.pam_environment, but it doesn't work, too.

Looking online I saw a bunch of discussions mentioning this problem, try checking this one for instance.

Keep me updated!

Hello GyulyVGC,

The thread you've linked seems to have the problem of missing entries for the XDG_RUNTIME_DIR variable.
I've tried a few things:

% sudo bash
# export XDG_RUNTIME_DIR=/run/user/0
# RUST_BACKTRACE=full /home/myuser/.cargo/bin/sniffnet

Do you have any other idea how I can debug that problem?

Thank you very much.

from sniffnet.

In the next days I'll do more careful researches.

In the meantime, let me know if you manage to fix the issue.

from sniffnet.

Can you try doing sudo apt-get install xdg-utils --fix-missing, closing the shell and opening Sniffnet from a new shell?

Also try checking issue #23. It has the same error message when trying to push a button after the application is started. I don’t think it’s much related even if the error is the same, but who knows.

I've reinstalled xdg-utils (emerge -av xdg-utils as it is gentoo) and opened a new shell but it doesn't change anything.

I don't think the problem is with xdg-utils. If I use

export XDG_RUNTIME_DIR=/run/user/0

the XDG_RUNTIME_DIR is not shown anymore. I still get only a glimps of the frame of the application, and then it crashes with the above error message. The libpcap-dev is installed. Is there a dependency that you use for the graphic that is missing? As I use gentoo and not a debian distribution maybe there is some difference here?

from sniffnet.

Actually yes and that may be the problem.
The GUI library I used relies on wgpu and here you can find the supported platforms.
