[Buildroot] ISO menu option

[Buildroot] ISO menu option

[vbr vbr]

Hi,

I am new to buildroot. First congratulations for the awesome tool!

I noticed that when I pick the i386 as a target platform, the ISO option is
present under fs. However, if I pick a different target, say x86_64, the ISO
menu option disappears. I was wondering what the reason was behind this as I
am trying to build an ISO image for x86_64.

Thanks for your help

Vince

Which version of Buildroot are you using ?

In Buildroot 2010.05, it's correct that the ISO9660 option was only
available for the i386 architecture. In the current git of Buildroot,
we've fixed this, and it is now possible to enable the generation of
ISO9660 filesystem image for both i386 and x64_64 (see
commit c7ee5853a0d54a32aa69a4e4065e6ecdd63c4a4c).

BTW, I would be interested by your feedback on the ISO images Buildroot
generates. I've reworked the code that does this, but as I don't use
these myself, I don't know what kind of use cases ISO images are
supposed to solve. Therefore, your feedback on whether the ISO images
generated by Buildroot are useful or incomplete would be very
interesting.

Thanks,

Thomas

[Buildroot] ISO menu option

Thanks for the quick reply. I am using the stable 2010.05. I also checked
out the latest code from git and saw the change you are mentioning but I
haven't tried it yet.

ISO image is a convenient way for us to download and store the image on a
remote server and boot the target system with the remote ISO.

I haven't been able to make it work yet with the ISO image produced by
buildroot. Trying this as a side project, but I will definitely let you know
if I can get it to work. We already have a solution in place, but using
buildroot would be a great improvement over what we have today.

Also, I am trying to keep the config files/software I need outside of
buildroot directory and creating a script to download buildroot and install
my specific config (checked in our own SCM) in there. For example, I need a
more up-to-date version of some Linux drivers and I need to copy my
busybox/kernel/uclibc config files to the right place after unpacking
buildroot. The reason I am doing this is I want to be able to upgrade
buildroot easily when a new stable version is released by just changing the
buildroot version to download in the script and I want to avoid checking
buildroot code in our scm. That would be more painful to upgrade. Are there
guidelines to do that?
Not sure if this is clearly explained.

Thanks
V
