This directory contains the data needed to build the locale data files
10
to use the internationalization features of the GNU libc.
12
POSIX.2 describes the `localedef' utility which is part of the GNU libc.
13
You need this program to "compile" the locale description in a form
14
suitable for fast access by the GNU libc functions. Any compilation is
15
based on a given character set.
17
Once you run `make install' for the GNU libc the data files are
18
automatically installed in the right place, ready for use by the
21
To compile the locale data files you simply have to decide which locale
22
(based on the location and the language) and which character set you
23
use. E.g., French speaking Canadians would use the locale `fr_CA' and
24
the character set `ISO_8859-1,1987'. Calling `localedef' to get the
25
desired data should happen like this:
27
localedef -i fr_CA -f ISO-8859-1 fr_CA
29
This will place the 6 output files in the appropriate directory where
30
the GNU libc functions can find them. Please note that you need
31
permission to write to this directory ($(prefix)/share/locale, where
32
$(prefix) is the value you specified while configuring GNU libc). If
33
you do not have the necessary permissions, you can write the files into an
34
arbitrary directory by giving a path including a '/' character instead
35
of `fr_CA'. E.g., to put the new files in a subdirectory of the
36
current directory simply use
38
localedef -i fr_CA -f ISO-8859-1 ./fr_CA
40
How to use these data files is described in the GNU libc manual,
41
especially in the section describing the `setlocale' function.

48
One more note: the `POSIX' locale definition is not meant to be used
49
as an input file for `localedef'. It is rather there to show the
50
values with are built in the libc binaries as default values when no
51
legal locale is found or the "C" or "POSIX" locale is selected.

The collation test suite
55
########################
57
This package also contains a (beginning of a) test suite for the
58
collation functions in the GNU libc. The files are provided sorted.
59
The test program shuffles the lines and sort them afterwards.
61
Some of the files are provided in 8bit form, i.e., not only ASCII
62
characters. So the tools you use to process the files should be 8bit
65
To run the test program the appropriate locale information must be
66
installed. Therefore the localedef program is used to generate this
67
data used the locale and charmap description files contained here.
68
Since we cannot run the localedef program in case of cross-compilation
69
no tests at all are performed.
