Amlogic buildroot help

[dsh]

If you have ever compiled buildroot from Amlogic, please help me. I am trying to learn develop app on amlogic based device. 

 

First I was getting compile error on 64bit Ubuntu 16.04. 

Something like this. Even though there was a file, 'bash' couldn't find  or run.

/bin/bash: /root/buildroot/x86/xxxx-gcc: No such file or directory

Thinking it's something to do with 64 bit OS, I switched to 32 bit Ubuntu 16.04.

 

However after about 2 hours I'm getting following error.

Again those files exists. File command shows following.

arm-none-eabi-gcc: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.24, BuildID[sha1]=0c937a9bf52dcb3a4e5ced5efc41213730d23b54, stripped

Am I  doing anything wrong? Any input will be appreciated. 

 

Thanks in advance.
