Maybe this conversation could be relevant here, so linking the issue: #33

from integration_whiteboard.

I managed to get the Nextcloud Spaceboard Integration working manually on arm64.

For the brave:
This assumes you've already downloaded the app through Nextcloud.
Also:
current user: not root (got to use sudo)
web-user = www-data

install node.js 16 + npm
0.1 (optional: make it work with PHP 8.0)
fixes to compile Node.js sqlite3 native bindings for arm64

# adjust path to your nextcloud apps directory
# this will be our working directory for the next commands
cd /var/www/nextcloud/apps/integration_whiteboard/data/spacedeck

1.1 once in that directory, edit package.json with your favorite terminal editor and paste:

expand package.json file

save this as phantomjs.patch, then:

sudo patch ./helpers/phantom.js phantomjs.patch

sudo rm -r node_modules/sqlite3
sudo npm install --build-from-source=sqlite3 --production

use vercel's pkg, not nexe to put it all into one single binary

sudo npm install --global pkg
sudo pkg -c package.json -t linux-node16-arm64 spacedeck.js
sudo chown -R www-data:www-data .
sudo mv spacedeck.nexe.bin spacedeck.nexe.bin.x86_64
sudo mv spacedeck-open spacedeck.nexe.bin
# (re-) enable whiteboard_integration app in nextcloud
# this copies the current folder to `$NC_DATA_DIR/appdata_random-string/spacedeck/`

be happy and use Spacedeck whiteboards

@teutat3s,

I try the version without the npm and node update. As far as I see, your patch has an error at line 14.
my patch looks like this:

phantomjs.patch.txt

from integration_whiteboard.
