How can I make a .img or .iso file by the image in chroot..

[teke...@gmail.com]

  I want send the image to a friend, then he can simply make a USB key, and he don't need to do it in a chroot..Dose someone have any suggestion to achieve that?

  and can chromium os build in 64bit Ubuntu run on 32bit cpu? Or it is decide by the board I choose? 

• x86-generic - builds a generic image suitable for computers with a x86-compatible CPU (32 bit)
• amd64-generic - builds a generic image suitable for computers with a x86_64-compatible CPU (64 bit)
• arm-generic - builds a generic image suitable for computers with an ARM CPU (32 bit)

but I build a x86-generic image,it can boot normal on a 64bit cpu notebook,but when boot from a 32bit cpu ,just blackscreen after Chromium icon appeared..

Ah! If that's all you want to do, just build the chromiumos_image.bin, and
make your .iso image with a file system containing just that file. Then your
friend can copy it to his USB stick.

eee,is the  chromiumos_image.bin in the folder I build by the ./build_image --board=${BOARD}command? And how to make a bootable .iso file by it? Use mkisofs seems not work easy.

You don't make a _bootable_ .iso that way. Basically, it's not possible to make
a bootable Chromium OS image with media that's read-only. The point is to
make a simple data disk that you can give to your friend.

OTOH, if you can give him a disk, you can give him a USB stick.
Unless you're trying to send it in the mail, and the DVD is a more
convenient package...

If you just want to provide something for download, provide the
chromiumos_image.bin created by build_image: that's the thing that goes
onto USB in the first place.

You have to dump the contents of the file onto a USB stick.
The 'dd' command will do that for you; that's how image_to_usb.sh
works. That's a standard UNIX command available on Linux and
Mac OS X. If all your friend has to work with is Windows, you should
probably just mail him a USB stick. :-(
