Bash: ./neolink: No such file or directory

[TheGroundZero]

Describe the bug

I downloaded the Debian release of Neolink, installed the GStreamer dependancies and am now trying to launch the application.
Bash complains that it cannot find a file/directory with the name.

I did chmod +x to allow execution.

To Reproduce

$ apt install libgstreamer1.0-0 gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-libav gstreamer1.0-doc gstreamer1.0-tools gstreamer1.0-x gstreamer1.0-alsa gstreamer1.0-gl gstreamer1.0-gtk3 gstreamer1.0-qt5 gstreamer1.0-pulseaudio
$ wget https://nightly.link/thirtythreeforty/neolink/workflows/build/master/release-i386-buster.zip
$ unzip -d neolink release-i386-buster.zip
$ cd neolink/
$ wget https://raw.githubusercontent.com/thirtythreeforty/neolink/master/sample_config.toml
$ chmod +x ./neolink
$ ./neolink --config sample_config.toml

-bash: ./neolink: No such file or directory

Expected behavior

Neolink starting with the sample (or my custom) config.

The interpretor is /lib/ld-linux.so.2.

Can you confirm that file exists.

Also can you run uname -m and tell me the architecture

$ uname -m
x86_64

[QuantumEntangledAndy]

P.s. Its late in my timezone so I won't be able to reply until tomorrow now.

But if the uname -m tells you your arch is not i368 please go and download the right neolink for your arch.

As there's no x86_64 for Debian, I'd better set up a Ubuntu container?

[TheGroundZero]

Removed my Debian container and replaced with Ubuntu 20.04

# cat /etc/os-release
NAME="Ubuntu"
VERSION="20.04.2 LTS (Focal Fossa)"
ID=ubuntu
ID_LIKE=debian
PRETTY_NAME="Ubuntu 20.04.2 LTS"
VERSION_ID="20.04"

Repeated previous steps, but downloading the ubuntu_x86_64 release.

[TheGroundZero]

So it was my mistake for downloading the 32-bit release on a Debian x64 system.
Running Ubuntu x64 and the x64 release seems to work.

To add the camera in iSpy:

1. add camera as Generic RTSP
2. use rtsp://<ip>:8554/camera_name/mainStream as URL
3. let it search for the camera and pick one of the proposed URLs, none will match the correct URL
4. edit camera to put rtsp://<ip>:8554/camera_name/mainStream back as URL

[QuantumEntangledAndy]

Glad you got it working. I had a feeling it was this when I saw you were using the i386.

You mention your using a container? There is a know issue with docker and very large (4k) camera streams where it will segfault #46. Although this may be fixed now with the newer gstreamers (maybe closed in #141).

[TheGroundZero]

I'm running a Linux Container (LXC) in Proxmox, not sure if that has the same issues as a Docker container.
But if the newer GStreamer fixes it, I should be fine anyway?

[MRobi1]

Are there plans for releasing an x86_64 debian version in the future?
Seems like anybody running debian on any sort of modern hardware would be running 64bit not 32bit.

I've run into this same issue with a Proxmox LXC. Would like to have neolink and zoneminder running in the same LXC.
I can run neolink just fine in a ubuntu lxc but have issues getting zoneminder going because of AppArmour.
I can run neolink just fine in a debian lxc but can't run neolink because it's i386. Tried running it in docker but it continuously crashes.
So it kind of sucks I'm stuck devoting resources to 2 containers instead of just 1.

[QuantumEntangledAndy]

@MRobi1 I am a bit confused why you cannot use the ubuntu x86_64 version on the debian

p.s. A new issue is best

[MRobi1]

I'm going to just come out and say I didn't even realize that was possible. LOL
Loaded it up and works like a charm! Thanks for the tip.

[QuantumEntangledAndy]

Hmm perhaps we should edit the readme to say Ubuntu/Debian
