View source for WHDD Live ISO Boot CD (old)

[[Category:Linux]]

[http://whdd.org/ WHDD] is created by Andrey Utkin. This is a small 'Live' image to run standalone.

=Prebuilt WHDD Live ISO=

For people who just want it without building themselves

[https://mega.co.nz/#!cJYVVawY!YQwqkIe1czoaRH-Ab-4WdynyQbVDZQK-_GeYDV2HeRg Prebuilt ISO]

==Boot from Syslinux/PXELinux==

<pre>
Label WHDD V2
LINUX /memdisk iso
INITRD /whdd-live.iso
</pre>

or separate (not in ISO)

<pre>
Label WHDD V2
LINUX /bzImage
INITRD /initramfs
</pre>

=Build it yourself=

==Download Toolchain==

This uses uClibc to create smaller C library files and hence a smaller output.

==Create folders==
Create directory structure somewhere;

<pre>
mkdir -p patch source custom
</pre>

==Download Sources==

<pre>
cd source
git clone https://github.com/krieger-od/whdd
git clone git://git.busybox.net/busybox
curl https://www.kernel.org/pub/linux/utils/boot/syslinux/syslinux-6.02.tar.xz | tar -Jx
svn co http://svn.code.sf.net/p/smartmontools/code/trunk/smartmontools smartmontools

curl http://invisible-island.net/datafiles/release/dialog.tar.gz | tar -zx

==Dir structures==

Initially you should just have folders custom, patch, source and the Makefile.

(Ignore other folders for the moment, this is after it has been built to give you an idea how it should look)

==Patches==

These are needed after git pull at time of writing

===busybox-shell_ash.c.patch===
This makes busybox set LANG as a default ENV so UNICODE works, required by WHDD.

==Makefile==

This should be one level below the folder structure's created, see the dir layout

* Change TCHAIN to where your toolchain is, buildroot ones have hard coded paths, x-tools (crosstools-ng doesn't?)

=Build It=

Assuming you have all the files extracted and laid out correctly, just run 'make'.

*make = build everything i.e. create kernel 'bzImage', programs and system archive 'initramfs' , iso
*make xxxxx = build program xxxxx (to 'destdir/')
*make linux = just build (compile) kernel ('output/bzImage')
*make progs = just build (compile) all the progs ('destdir/')
*make system = clean/strip/cpio archive programs ('output/initramfs')
*make iso = create ISO from bzImage and initramfs

=Test It (with QEmu)=

*create a 50Mb test 'hard drive' image

qemu-img create -f qcow whdd.qcow 50M

*fire it up

qemu-system-x86_64 -kernel output/bzImage -initrd output/initramfs -hda whdd.qcow

Running the 'read test' should produce something like this after a couple of seconds;
