Generating locales is possible in two situations: - With the internal toolchain backend, when the uClibc library is used. With uClibc, locales are generated at build time of the C library, so with uClibc it's only possible with the internal toolchain backend. - With either the internal or external toolchain backend when the glibc library is used. With glibc, locales can be generated afterwards, using the host-localedef utility. Until we had the musl C library supported in the internal toolchain backend, the condition: BR2_TOOLCHAIN_BUILDROOT || BR2_TOOLCHAIN_USES_GLIBC was correct to capture the above two situations. Now that we have musl support in the internal toolchain backend, then BR2_TOOLCHAIN_BUILDROOT is incorrect, and we should use BR2_TOOLCHAIN_BUILDROOT_UCLIBC instead. Basic locale support in musl has appeared in musl 1.1.4, but we are not yet capable of generating the locale files for musl.

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
