I want to build a IDE on android tablet that can compile c++ for AVR mcus like arduino uno. So I need to build a gcc that run on android and can cross compile AVR executable. Can any one give me some idea about how to do it? Thanks a lot.
Update:
I compile the toolchain using script from CC Tools with android NDK r9d source code on Linux and get the following error:

Does any one knows how to resolve this issue?
You may want to look into CCTools, which offers an AVR cross compiler, instead of rolling out your own. Cheers.
