|       <p>
| Debian supports an ever-increasing number of architectures.  Even if
| you are not a porter, and you don't use any architecture but one, it
| is part of your duty as a maintainer to be aware of issues of
| portability.  Therefore, even if you are not a porter, you should read
| most of this chapter.

|       <p>
| Porting is the act of building Debian packages for architectures which
| is different from the original architecture of the package
| maintainer's binary package.  It is a unique and essential activity.
| In fact, porters do most of the actual compiling of Debian packages.
| For instance, for one <em>i386</em> binary package, there has to be a
| recompile for each architecture, which is around five more builds.

| 	<p>
| Porters have a difficult and unique task, since they are required to
| deal with a large volume of packages.  Ideally, every source package
| should build right out of the box; unfortunately, this is often not
| the case.  This section contains a checklist of ``gotchas'' often
| committed by Debian maintainers -- common problems which often stymie
| porters, and make their jobs unnecessarily more difficult.

| The first and most important watchword is to respond quickly to bug or

| If the package builds out of the box for the architecture to be ported
| to, you are in luck and your job is easy.  This section applies to
| that case; it describes how to build and upload your binary NMU so
| that it is properly installed into the archive.  If you do have to
| patch the package in order to get it to compile for the other
| architecture, you are actually doing a source NMU, so consult <ref

| Sometimes you need to recompile a packages against other packages

| version number in this case, so that the upgrade system can function

| no need in this case for all architectures to recompile.  You should
| set the version number as in the case of NMU versioning, but add a
| ``.0.'' before the the NMU version.  For instance, a recompile-only

| Firstly, the acceptable waiting period -- the time between when the

| Secondly, porters doing source NMUs should make sure that the bug they
| submit to the BTS should be of severity `important' or greater.  This
| ensures that a single source package can be used to compile every
| supported Debian architecture by release time.  It is very important
| that we have one version of the binary and source package for all
| architecture in order to comply with many licenses.

| Porters should try to avoid patches which simply kludge around bugs in
| the current version of the compile environment, kernel, or libc.
| Sometimes such kludges can't be helped.  If you have to kludge around
| compilers bugs and the like, make sure you <tt>#ifdef</tt> your work
| properly; also, document your kludge so that people know to remove it
| once the external problems have been fixed.

| The <package>buildd</package> system is used as a distributed,
| client-server build distribution system.  It is usually used in
| conjunction with <em>auto-builders</em>, which are ``slave'' hosts
| which simply check out and attempt to auto-build packages which need
| to be ported.  There is also an email interface to the system, which
| allows porters to ``check out'' a source package (usually one which
| cannot yet be autobuilt) and work on it.

| We are very excited about this system, since it potentially has so
| many uses.  Independent development groups can use the system for
| different sub-flavors of Debian, which may or may not really be of
| general interest (for instance, a flavor of Debian built with gcc
| bounds checking).  It will also enable Debian to recompile entire
| distributions quickly.
