Not working on linux

[valeriob]

Hi,
running the library on linux it does not seems to have the wkhtmltox0 library embedded, since it produces the following error :

 An unhandled exception has occurred while executing the request.

System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.DllNotFoundException: Unabl to load shared library 'wkhtmltox0' or one of its dependencies.

the nuget packages for WkHtmlToXSharp.Linux32 version 1.2.* are all very small (20k) i doubt it has the linux lib embedded, 1.1.latest it's 15+Mb instead, looks working.

Unfortunatly version 1.1.23.22 does not work on windows either :(

Can you point me to a solution ?

fetch a wkhtmltox0.so for your linux distro from wkhtmltopdf website, and copy it to the same folder where you are running your mono app, and try again. Regards

Thanks, I have tried that with the same result. I'm running on Ubuntu server.

ensure you have all wkhtmltox0.so dependencies by running ldd against it.
