Strange build_native.sh error

Hello everyone,
I’ve start a new project with cocos2d-x and like I did in the others projects, i’ve made the testings builds in win32, but now that i want to run the project in android the build_native script gives me a strange error.

Also i’ve noticed that running build_native creates the obj and the libs folder in a different directory that the main project.

Someone can help me with this?
Thanks.
