I try to make a little frontend for xine in c++.

I will use it in VDR for the VDR-Plugin-Xine

I get the following linking error when I try to Compile

Code:

You have defined your 'main' function within the 'XineFrontend' namespace. You might also want to take a look at how you're defining all those static member variables (see here, too).
