In order to use locale support on a Linux system, you need locale data to be present: * on a (e)glibc based system, this data is typically in the /usr/lib/locale/locale-archive file, which can be created and extended using the localedef program * on an uClibc based system, the set of supported locales is defined at build time by an uClibc configuration option. This patch implements generating locale data for the following cases: * Internal toolchain * External toolchain based on (e)glibc. uClibc external toolchains are not supported, because with uClibc, the set of supported locales is defined at build time. CodeSourcery and Linaro toolchains have been tested, Crosstool-NG toolchains are believed to work properly as well. * Toolchains built using the Crosstool-NG backend, but only (e)glibc toolchains. This feature was runtime tested with internal uClibc toolchain, CodeSourcery ARM toolchain and Linaro ARM toolchain, thanks to a simple C program that shows the data and a gettext translated message. Note that this option differs from the "purge locales" option, which is responsible for removing translation files and other locale stuff installed by packages. At some point in the future, we may want to clarify the respective roles of those options.

To build and use the buildroot stuff, do the following:
1) run 'make menuconfig'
2) select the packages you wish to compile
3) run 'make'
4) wait while it compiles
5) Use your shiny new root filesystem. Depending on which sort of
root filesystem you selected, you may want to loop mount it,
chroot into it, nfs mount it on your target device, burn it
to flash, or whatever is appropriate for your target system.
You do not need to be root to build or run buildroot. Have fun!
Offline build:
==============
In order to do an offline-build (not connected to the net), fetch all
selected source by issuing a
$ make source
before you disconnect.
If your build-host is never connected, then you have to copy buildroot
and your toplevel .config to a machine that has an internet-connection
and issue "make source" there, then copy the content of your dl/ dir to
the build-host.
Building out-of-tree:
=====================
Buildroot supports building out of tree with a syntax similar
to the Linux kernel. To use it, add O=<directory> to the
make command line, E.G.:
$ make O=/tmp/build
And all the output files (including .config) will be located under /tmp/build.
More finegrained configuration:
===============================
You can specify a config-file for uClibc:
$ make UCLIBC_CONFIG_FILE=/my/uClibc.config
And you can specify a config-file for busybox:
$ make BUSYBOX_CONFIG_FILE=/my/busybox.config
To use a non-standard host-compiler (if you do not have 'gcc'),
make sure that the compiler is in your PATH and that the library paths are
setup properly, if your compiler is built dynamically:
$ make HOSTCC=gcc-4.3.orig HOSTCXX=gcc-4.3-mine
Depending on your configuration, there are some targets you can use to
use menuconfig of certain packages. This includes:
$ make HOSTCC=gcc-4.3 linux-menuconfig
$ make HOSTCC=gcc-4.3 uclibc-menuconfig
$ make HOSTCC=gcc-4.3 busybox-menuconfig
