DE2 demonstration problems

I just purchased a DE2-50 board. 

I'm trying to make the DE2_NIOS_HOST_MOUSE_VGA demonstration to work on this board. I achieved to program the board with the right sof file but when i try to open and build the software with Nios II 13.0sp1 Software Build Tools for Eclipse nothing is possible. 

I follow  

7) Switch the workspace to the <install path>\DE2_NIOS_HOST_MOUSE_VGA folder. 

8) Build the project. (Project menu -> Build All) 

as said in the readme file but when i try to build the fucntion is greyed. 

Any idea ? 

Thanks

I answer myself 

It use the wrong directory. Using demonstrations in "DE2_demonstrations_Qsys" works better. In this dir i find a pdf file explainig how to regenerate bsp and solve some problems. 

But with this demonstration i have an error during the build :  

Description Resource Path Location Type 

Symbol 'VGA_BASE' could not be resolved main.c /DE2_NIOS_HOST_MOUSE_VGA line 99 Semantic Error 

Any idea ?
