[yocto] Yocto and Qt embedded

[Giovanni Foiani]

Hi Jessica,

I built separately the qte toolchain running:


   - bitbake meta-toolchain-qte

and the qte demo image (without toolchain) using Hob.
Now I need to integrate Yocto SDK and Qt Creator IDE.
I'm trying to configure Qt Creator to recognize Poky toolchain and Qt
Creator asks for the compiler path inside Poky SDK.
Where is the compiler located inside Poky SDK built from meta-toolchain-qte?

Thanks

Giovanni
