Hey, dude, I'm delighted to find your project on freelancer. I’m good at compiling android system and linux kernel, with several years of experience on linux kernel, android system, c/c++ programming.
Your compiling error should be blamed on your environment setup if the source code is complete. It's a problem of such familiarity that it makes me feel more confident to solve.
I can make a direction or assistance for you to solve these problem through telegram or skype, and hope to develop the long-term cooperation between us.
Thanks.
