1138	=head1 FULLY STATIC BINARIES - UCLIBC AND BUILDROOT
1139
1140	To make truly static (Linux-) libraries, you might want to have a look at
1141	buildroot (L<http://buildroot.uclibc.org/>).
1142
1143	Buildroot is primarily meant to set up a cross-compile environment (which
1144	is not so useful as perl doesn't quite like cross compiles), but it can also compile
1145	a chroot environment where you can use F<staticperl>.
1146
1147	To do so, download buildroot, and enable "Build options => development
1148	files in target filesystem" and optionally "Build options => gcc
1149	optimization level (optimize for size)". At the time of writing, I had
1150	good experiences with GCC 4.4.x but not GCC 4.5.
1151
1152	To minimise code size, I used C<-pipe -ffunction-sections -fdata-sections
1153	-finline-limit=8 -fno-builtin-strlen -mtune=i386>. The C<-mtune=i386>
1154	doesn't decrease codesize much, but it makes the file much more
1155	compressible.
1156
1157	If you don't need Coro or threads, you can go with "linuxthreads.old" (or
1158	no thread support). For Coro, it is highly recommended to switch to a
1159	uClibc newer than 0.9.31 (at the time of this writing, I used the 20101201
1160	snapshot) and enable NPTL, otherwise Coro needs to be configured with the
1161	ultra-slow pthreads backend to work around linuxthreads bugs (it also uses
1162	twice the address space needed for stacks).
1163
1164	If you use C<linuxthreads.old>, then you should also be aware that
1165	uClibc shares C<errno> between all threads when statically linking. See
1166	L<http://lists.uclibc.org/pipermail/uclibc/2010-June/044157.html> for a
1167	workaround (And L<https://bugs.uclibc.org/2089> for discussion).
1168
1169	C<ccache> support is also recommended, especially if you want
1170	to play around with buildroot options. Enabling the C<miniperl>
1171	package will probably enable all options required for a successful
1172	perl build. F<staticperl> itself additionally needs either C<wget>
1173	(recommended, for CPAN) or C<curl>.
1174
1175	As for shells, busybox should provide all that is needed, but the default
1176	busybox configuration doesn't include F<comm> which is needed by perl -
1177	either make a custom busybox config, or compile coreutils.
1178
1179	For the latter route, you might find that bash has some bugs that keep
1180	it from working properly in a chroot - either use dash (and link it to
1181	F</bin/sh> inside the chroot) or link busybox to F</bin/sh>, using it's
1182	built-in ash shell.
1183
1184	Finally, you need F</dev/null> inside the chroot for many scripts to work
1185	- F<cp /dev/null output/target/dev> or bind-mounting your F</dev> will
1186	both provide this.
1187
1188	After you have compiled and set up your buildroot target, you can copy
1189	F<staticperl> from the C<App::Staticperl> distribution or from your
1190	perl f<bin> directory (if you installed it) into the F<output/target>
1191	filesystem, chroot inside and run it.
