Linux compilation problem for orange pi 3.

danielkim71

Hello,

I want to build orange pi 3 images
when i compile in the order of "orange pi 3 user manual_v1.0.pdf"
building of u-boot, kernel  is OK,
but when i execute "build release image" menu, error occurred.
The error message is as follows.

I: Extracting mount...
I: Extracting util-linux...
I: Extracting liblzma5...
I: Extracting zlib1g...
Copy qemu emulator binary to rootfs.....
Copy debian-archive-keyring.....
Start debootstrap second stage.....
chroot: failed to run command ‘mount’: Exec format error
chroot: failed to run command ‘mount’: Exec format error
chroot: failed to run command ‘/debootstrap/debootstrap’: Exec format error

How can I solve this problem?

yes, you are right https://github.com/armbian/build is much better experience. compilet orange pi 3 image without any problems from first run in vagrant

Under which operating system are you trying to build an image?

problem is that script is trying to change root (chroot) to different architecture. you are using x86 and it cannot execute arm binaries but this build script also does not work on arm. i guess using qemu to run arm code and running arm chroot binary would solve this

commentig bellow code lines which were took from https://github.com/orangepi-xunl ... ter/rootfs_build.sh


it uses chroot binary from x86 platform to execute mount which is aarm64.

example from compilation script
chroot: failed to run command ‘mount’: Exec format error
chroot: failed to run command ‘mount’: Exec format error
chroot: failed to run command ‘/debootstrap/debootstrap’: Exec format error

Sorry, I mixed up the script. This https://github.com/armbian/build prepares everything. For Xunlong SDK I have no idea if it works but I guess it is also designed to run on Intel platform (cross compilation).
