This is the ARM toolchain:

ii binutils-arm-linux-gnu 2.18.1~cvs20080103-7 The GNU binary utilities, for arm-linux-gnu target
ii cpp-4.3-arm-linux-gnu 4.3.2-1 The GNU C preprocessor
ii g++-4.3-arm-linux-gnu 4.3.2-1 The GNU C++ compiler
ii gcc-4.3-arm-linux-gnu 4.3.2-1 The GNU C compiler
ii gcc-4.3-arm-linux-gnu-base 4.3.2-1 The GNU Compiler Collection (base package)
ii libc6-arm-cross 2.7-15 GNU C Library: Shared libraries (for cross-compiling)
ii libc6-dev-arm-cross 2.7-15 GNU C Library: Development Libraries and Header Files (for cross-compiling
ii libc6-dev-i386 2.7-16 GNU C Library: 32bit development libraries for AMD64
ii libgcc1-arm-cross 1:4.3.2-1 GCC support library
ii libstdc++6-4.3-dev-arm-cross 4.3.2-1 The GNU Standard C++ Library v3 (development files)
ii libstdc++6-4.3-pic-arm-cross 4.3.2-1 The GNU Standard C++ Library v3 (shared library subset kit)
ii libstdc++6-arm-cross 4.3.2-1 The GNU Standard C++ Library v3
ii linux-libc-dev-arm-cross 2.6.26-8 Linux support headers for userspace development (for cross-compiling)

armel will be -arm-linux-gnueabi or -armel-cross

To get the same output for armel:
$ emsetup -a armel --report

yes, its worked and listed all the installed toolchain for armel arm-linux-gnueabi*

Depends on what you want your root filesystem to be capable of doing.
The smallest package set currently used for Emdebian Crush is listed in:
/usr/share/emdebian-tools/emdebian.crossd

The autobuilder will use that set by default.

The actual set is subject to change, always take the actual package
names from the emdebian.crossd file. Add the list of "required"
binaries to the list of "base" binaries to get the complete package set.

required="busybox dpkg libstdc++6 libgcc1 libc6 cdebconf
debconf-shell libdebian-installer4 zlib1g libnewt0.52
libslang2 base-passwd"

base="apt gpgv libncurses5 libreadline5 readline-common
debianutils makedev whiptail gnupg udev base-files
debian-archive-keyring dhcp3-client
util-linux module-init-tools initscripts"

The autobuilder converts that into a set of source packages that it
builds with emdebuild and you can replicate the same step:

$ emdepends busybox dpkg libstdc++6 libgcc1 libc6 cdebconf debconf-shell libdebian-installer4 zlib1g libnewt0.52 libslang2 base-passwd apt gpgv libncurses5 libreadline5 readline-common debianutils makedev whiptail gnupg udev base-files debian-archive-keyring dhcp3-client util-linux module-init-tools initscripts
apt base-files base-passwd busybox bzip2 cdebconf debconf debian-archive-keyring debianutils dhcp3 dpkg e2fsprogs gcc-4.3 glibc gnupg libdebian-installer libselinux libtextwrap lsb makedev module-init-tools ncurses newt popt readline5 slang2 sysvinit tzdata udev util-linux zlib

after emsource gcc and while emdebuild its giving a dependency error.

I get strucked here to proceed further.... how to install those dependency gmp and mpfr... also tried manually by emsource those packages and strucked in some libtool errorl. I have attached the complete bug report with this mail .

emdepends converts a list of binary packages into a unique list of
source packages. With the exception of busybox, all the rest will build
using emsource and emdebuild as normal. You can build those in any order.

> Anyway i
> started with busybox from emsource ,but when i try to run #emdebuild
> --build-dep its giving me a error

Busybox is a manual build at the moment because we need to use a
version that is ahead of Debian. (It is the only package in that
condition because of the chpasswd bug.)

$ dget http://www.emdebian.org/packages/pool/main/b/busybox/busybox_1.11.1-1em1.dsc
$ cd busybox-1.11.1/
$ emdebuild -a armel

its giving me the error .whether i have to create a trunk link for this.

Cannot find debian/control anywhere!
Are you in the source code tree?
at /usr/bin/emdebuild line 210

As it is a manual build, the second and third runs through the build
(for the static and udeb packages) are not fully configured (I haven't
adapted the build config for the changes since busybox 1.10) so you
will get some questions you will need to answer. I just accept the
busybox default for each one.

busybox does not need an xcontrol file, it has no build dependencies
outside the toolchain itself.

> How can i get this xcontrol file inside the debian.

No need. All the xcontrol files you need are already available as
patches in Emdebian SVN.

? that is to cross-build packages that are completely unknown to
Emdebian and Debian - there should be no need for you to call this,
emdebuild does it for you.
