Eliminate GUI library dependencies for `nextcloudcmd`

[charlescurley]

Expected behaviour

On a headerless machine, nextcloud-desktop-cmd should not require X11.

Actual behaviour

I cannot purge about 315 MB of X11 libraries because nextcloud-desktop-cmd requires them.

Steps to reproduce

1. Install package nextcloud-desktop-cmd on debian 9.9 (stretch)
2. Attempt to purge X11 libraries. E.g.:

for i in $( pre x11 | cut -f1 ) ; do echo $i ; apt purge $i ; done

nextcloud-desktop-cmd will be either in the list of dependencies to be removed or in the list of packages to be removed with "apt autoremove".

Are there any plans to fix this issue ? Is there a way to compile the client without the GUI dependencies ?

I too need a NextCloud client on a headless Debian 9 server.

@charlescurley Have you found a workaround ? Thanks

I have not.

Same problem on Debian 10 Buster

In my opinion there should be a cmd only package and a full desktop package, even on Gentoo we have to compile half of QT and some other useless packages.

Here is the source code: https://github.com/nextcloud/desktop/tree/master/src/cmd

Building only nextcloudcmd is described in the top CMakeList.txt by setting BUILD_GUI=OFF.

I tried this build. There are a lot of Qt dependencies.

$ cmake -DBUILD_GUI=OFF -DBUILD_SHELL_INTEGRATION=OFF ..
...

 * Qt5Qml (required version >= 5.15.2)

$ make

This builds without any warnings on Ubuntu 21.10.

The result is definitely no GUI-less program.

Why this issue was closed? Is there a solution already? Are there any build options that solves this?

[ziQ]

This may not help the issue itself, but may be a quick workaround/alternative for other users like myself:

rclone (and rclone mount) works with Nextcloud Webdav. It is still pretty heavy, but at least not 315MB-with-GUI-heavy.

[ThaDaVos]

Any up date on this? The same for the closed issue about providing a separate download option? https://github.com/nextcloud/desktop/issues/1203

I am also looking for a headless solution and would rather use something provided by Nextcloud then mangling with WebDav myself
