How can I install cocos2D's document into my Xcode Help

I download the cocos2d's package from http://code.google.com/p/cocos2d-iphone/downloads/list. My Mac has already install the doxygen. But when I build the cocos-2d Document, lots of error occured.

like this:

error: problems opening map file /Developer/cocos2d-iphone-0.99.5/build/cocos2d-ios.build/Release-iphonesimulator/cocos2d-documentation.build/doxygen_output/html/_c_c_block_support_8h__incl.map for inclusion in the docs!

If you installed Graphviz/dot after a previous failing run,

try deleting the output 开发者_JAVA技巧directory and rerun doxygen.

How can i do that.

Thanks!
