qBittorrent 5.1.0 libtorrentv1 build is incorrectly using libtorrent v2

[crzidea]

Hi, thank you for maintaining this project!

I’ve noticed that the static build for qBittorrent 5.1.0 tagged as using libtorrent v1 is actually built against libtorrent v2.

I'm using the Docker image linuxserver/qbittorrent:libtorrentv1, which uses the static executables from this repository. The intent of that image is to use libtorrent v1, but when using the image version that includes qBittorrent 5.1.0, the executable appears to be built with libtorrent v2.

You can inspect the build process of the problematic Docker image here:
👉 https://hub.docker.com/layers/linuxserver/qbittorrent/libtorrentv1/images/sha256-630c23d777229ec4175650cd969611541469fbb000c8a438aa932410ea9495c9

How I verified:

In the qBittorrent Web UI:

• Navigate to Help -> About -> Software Used
• The libtorrent version is reported as 2.x.x

This contradicts the expectation that this is a libtorrent v1 build.

Temporary workaround:

I rolled back to the Docker image:

• linuxserver/qbittorrent:5.0.5-libtorrentv1

This version correctly uses a binary linked against libtorrent v1 and works as expected.

Could you please check the static build for qBittorrent 5.1.0 tagged as libtorrentv1 and ensure it is actually built with libtorrent v1? Let me know if I can provide any more information.

Thanks again for your work on maintaining these builds!

I'm pretty sure you are looking at the wrong image and I cannot reproduce your issue. I tested x86_64 and aarch64
