library issues

Using Arduino IDE 1.x
1

Hi, so i have tried to download a library from;Download | Wayne and Layne. Now I made a library folder in sketchbook and put the library in there. Now win I open arduino it says;
The library "VideoGameShieldLibraries-2012-09-01-2" cannot be used. Libraries names can only contain basic numbers and letters.

How do i fix this?
thanks

Change the name. It's telling you that you can't have dashes in the folder name.

how do you do that?

wait I got it. Now when I try and run the nunchuck demo this error appears;
Nunchuck does not have a name

how do I fix this?

That's not an error. It's an example sketch.

6

ok, well still how do I change this so i can run it?

7

Start by posting the error you are actually getting.

8

ok here it is

nunchuck_demo:26: error: 'Nunchuck' does not name a type
nunchuck_demo.cpp: In function 'void setup()':
nunchuck_demo:30: error: 'nunchuck' was not declared in this scope
nunchuck_demo:30: error: 'NUNCHUCK_PLAYER_1' was not declared in this scope
nunchuck_demo.cpp: In function 'void loop()':
nunchuck_demo:36: error: 'nunchuck' was not declared in this scope

I think I didn't set up the library right.

go here and go down to contributed libraries and see if you are doing is like this.

10

Ok yeh I did that and the library shows up in the contributed library parts but it still says the same error

11

I just went and installed the libraries. Examples compiles fine for me.

In your libraries folder did you leave the libraries in a "VideoGame"ShielLibraries" folder or did you just move the libraries into the folder individually?

what i have is ...\arduino-1.0.1\libraries\Nunchuck

12

I moved the entire folder in. Not each individually

13

Put them individually as i have. Mine compiles fine and your should too once the IDE can find nunchuck.h
