About aarch64 binary compiling #43

I have a raspberry pi3 model b and set that device with 64bit os. the output of command 'uname -a' is like this. Linux raspberrypi 4.9.58-v8+ #1 SMP PREEMPT Sun Oct 29 16:25:42 JST 2017 aarch64 GNU/Linux I have a question about compilation at aarch64 kernel.

I want to make 64bit executable file with aarch64-linux-gnu-gcc-6.4.0 so when I try aarch64-linux-gnu-gcc-6.4.0 test.c , the output of that command is fatal error: sys/cdefs.h: No such file or directory

I google it and I knew that I should install the needed lib like g++-multilib for arm64 version and for this, the arm64 version of apt repo should be set.

so I tried to add the debian arm64 apt repo. but I can not still install the suitable libraries for solving that compilation issues. please help me for solving that problem!

Are you trying to compile from your raspberry or cross-compile? Eg. from amd64 to arm64?

I compiled the 64bit kernel with cross-compile at my amd64 desktop

@leesera I suggest you to compile the binary in Docker ( you should docker build yourself via Dockerfile in this repo)
