Sadly, I do not recall the details, and the little information that was 
available on the net has been gone.

But judging from a blog post of mine [1], it looks like Michael Meeks at the 
time ported the support to run with Mono.   Other than that, I do not have more 

I managed to track down some old Addin for MonoDevelop, and you can maybe use 
this as a starting point for your investigations:

I suggest you reach out to the open office team.

Ok, Thanks.
With Ubuntu > 12.04 can’t find “cli-cppuhelper” no more.
Is this a problem within mono or libreoffice?
If you use libreoffice > 3.5 you will see that it will not work.

When I last used it, all the work took place on Unix, I do not recall using 
Windows at all.

Hi all,
i just restart working on a project that uses LibreOffice(CLI) from mono.
Now I am wondering that the assembly’s (cli_cppuhelper.dll) only run on Windows?
Is there is a way to get this working again?
