@RyuShai As I said on in your sysroot which you use to build for your target device. It doesn't help to install it on your host machine as you're building for another machine with different architecture (ARM). Your host machine is x86_64, right? If you install libs there they are for x86_64 as well - you cannot use them on ARM. Usually if you cross compile for other architectures you have a sysroot which contains all needed header files and libraries.
