[[!meta title="Packaging"]]
There are always more source packages to be made. Software that should be
packaged soon includes:
* **[Dropbear](http://matt.ucc.asn.au/dropbear/dropbear.html)**
Dropbear is a small SSH server and client, in many ways compatible with
OpenSSH.
In addition to the basic packaging work, there is work to be done on a
service script (just a simple shell script in `/etc/init.d`) and `postinst`
and `postrm` maintainer scripts to generate and delete the SSH host key
pair.
* **[GNU Autoconf](https://www.gnu.org/software/autoconf/)**
GNU Autoconf generates `configure` scripts that are used to configure
software packages for building.
* **[GNU Automake](https://www.gnu.org/software/automake/)**
GNU Automake generates `Makefile.in` files that are used to build software
packages.
* **[GNU M4](https://www.gnu.org/software/m4/)**
GNU M4 is a macro processor, notably used by GNU Autoconf.
* **[Perl 5](http://www.perl.org/)**
Perl 5 is a language interpreter, especially popular in systems
administration and software build and installation systems.
Unmodified Perl 5 source is impossible to cross build without executing
software on the host system (in GNU Autoconf terms, the system for which the
package is built). See [this mailing list thread][perl-cross-building] for
more information. We will need to modify Perl's build system a bit before
we can build a package.
* **[GNU Multiple Precision Arithmetic Library (GMP)](http://gmplib.org/)**
GMP is a free library for arbitrary precision arithmetic, operating on
signed integers, rational numbers, and floating point numbers. It is used
by GCC.
* **[GNU MPFR](http://www.mpfr.org/)**
MPFR is a C library for multiple-precision floating-point computations with
correct rounding.
* **[GNU MPC](http://www.multiprecision.org/index.php?prog=mpc)**
MPC is a C library for the arithmetic of complex numbers with arbitrarily
high precision and correct rounding of the result.
* **[GNU Binutils](https://www.gnu.org/software/binutils/)**
GNU Binutils is a collection of binary utilities, including a linker and
assembler.
Binutils and GCC are part of the
[[multiarch_cross_toolchain|dev/todo/multiarch-cross-toolchains]] project.
* **[GNU Compiler Collection (GCC)](http://gcc.gnu.org/)**
GCC is an optimizing compiler with frontends and libraries for a wide range
of languages.
Binutils and GCC are part of the
[[multiarch_cross_toolchain|dev/todo/multiarch-cross-toolchains]] project.
* **[GNU Make](https://www.gnu.org/software/make/)**
GNU Make is a tool that automatically builds software packages.
Note: [A small patch](http://bugs.debian.org/618840) exists in Debian to
enable Make to use multiarch library paths. We can do something similar
(but with host-architecture paths rather than build-architecture paths).
* **[DAS U-Boot](http://www.denx.de/wiki/U-Boot)**
U-Boot is a bootloader used on many embedded computers, including the
BeagleBoard-xM.
