Get syncfusion pdf viewer working in packaging or alternative pdf viewers?

[gjwgit]

Describe the Bug

Syncfusion is being used to view pathology PDF docs. It is a nice viewer but need to confirm if it is open source licensed. If not then this task is to identify an alternative PDF viewer.

If staying with syncfusion then need to resolve this: when building Linux packages (deb or snap) that include syncfusion, the resulting package can not load the libpdfium library (syncfusion_pdfview_linux). It is not clear yet why. A local build works just fine getting the library from /home/user/git/github/anusii/healthpod/linux/flutter/ephemeral/.plugin_symlinks/syncfusion_pdfviewer_linux/linux/include/pdfium/x64/bin/libpdfium.so but a github workflow build does not find that path

wget https://solidcommunity.au/installers/healthpod_amd64.deb
dpkg --install healthpod_amd64.deb
healthpod

This results in:

healthpod: error while loading shared libraries: libpdfium.so: cannot open shared object file: No such file or directory

• Why is the library not being found
• Is syncfusion licesensed for OpenSource?

The following works, but why isn't the flutter builder for linux getting this included?

LD_LIBRARY_PATH=/usr/lib/healthpod/lib/ /usr/bin/healthpod

Thus, add the following as the postinst script for the deb package.

#!/bin/sh
set -e
echo "/usr/lib/healthpod/lib" >> /etc/ld.so.conf.d/healthpod.conf
ldconfig

Hi @gjwgit, I noticed you have added these lines to deb.sh. Should I explore replacing the Syncfusion PDF Viewer with an alternative PDF viewer, or just get Syncfusion working in packaging?

Let's see how this goes for now. Thanks for parking it.
