Can you please post the full build log?

[kingzcheung]

Sorry,I had found out how to solve it.

[twistedfall]

Please do share your solution!

[kingzcheung]

Ok. In fact, I can't share my solution because I didn't have it documented. It seems that I did not specify the cross-compilation related toolchain directory normally, resulting in some errors.
