Re: [Linker Error] Unresolved external

OK I got it.
I had to reinstall the 8 release and change some install settings.
So now I have the include and lib folders.
But I got a new error message now. It say that I can not install
and start the service because the user grafl is member of admin group.

How can I start it remaining in the admin group?
