Ubuntu 22.04 - Unable to load native library #80

Closed tpurschke closed 2 years ago

tpurschke commented 2 years ago

When running on Ubuntu 22.04 I get the "usual" error message: One or more errors occurred. (Unable to load native library. The platform may be missing native dependencies (libjpeg62, etc). Or the current platform is not supported.)

Working fine on all other platforms tested: 18.04, 20.04, debian 10 + 11 Has anyone been able to get it to run on Ubuntu 22.04?

Installed libraries on test system:

Hmm, there may be some other dependency in that environment, I have not tested Ubuntu 22.

tpurschke commented 2 years ago

you were right:

By downloading and installing the pre-compiled version from https://wkhtmltopdf.org/downloads.html found the missing dependency.

So the following package installation makes PDF generation possible on ubuntu 22.04:

sudo apt install libgdiplus libc6-dev libjpeg62 xfonts-75dpi

Thanks Hakan for pointing me in the right direction.
