LPRng, Internationalization and gettext

Internationalization in LPRng is done using the gettext
packages.   There are three possibilities to use this
functionality:

a)  no internationalization (default)
      ./configure
b)  installating and compiling the gettext support library
    as part of LPRng:
      ./configure --enable-nls --with-included-gettext
c)  nationalization if system supports it and gettext installed
    on your system:
      ./configure --enable-nls

You may discover that system support for NLS has been put into
/usr/local/{include,lib}.  Sometimes the C compiler does not
search these directories by default and you will need to use:

 configure '--with-cppopts=-I/usr/local/include' \
   '--with-ldopts=-L/usr/local/lib'

If your system does not have the gettext code installed,
then you can simply install the necessary libraries as
described below.

How to Install the gettext software:

1. Get the gettext distribution and install it on your local system

   ftp://prep.ai.mit.edu/pub/gnu/gettext/gettext-<version>

   Unpack it by using:

    tar zxvf gettext-<version>.tgz
    cd gettext-<version>

   Read the documentation.  It is pretty straight forward with
   respect to installation.

2. If you want to install the distribution on your system
   configure, make and install the distribution.  The
   following is an outline of the commands:

        tar zxvf gettext-<version>.tgz
        cd gettext-<version>
        ./configure --prefix=/usr --with-included-gettext
        make
        su
        make install

   Now reconfigure and remake LPRng:
        cd .../LPRng
        rm -f config.cache
        configure --enable-nls

3. If you do not want to install the gettext distribution
   on your system, you will have to do a bit more work.

   First unpack the distribution and then
   copy the intl directories and contents
   to LPRng/intl:

        tar zxvf gettext-<version>.tgz
        cd gettext-<version>
        tar cf - intl | (cd ..../LPRng; tar xvf -)
        cd .../LPRng
        rm -f config.cache
        ./configure --enable-nls --with-included-gettext ....

UPDATES TO GETTEXT

If there has been a major update in the gettext distributution
then you will need to modify the gettext support files:

1. po/Makefile.in.in:

  Copy the gettext/po/Makefile.in.in file from
  the gettext distribution to the po directory:
  
       cp .../gettext-<version>/po/Makefile.in.in /tmp
       cd .../LPRng
       cp /tmp/Makefile.in.in po
       configure
  
  Modify the localedir information so the top level configure
  can update it:
  
  ORIGINAL:
    localedir = $(prefix)/share/locale
  
  NEW:
    localedir = @LOCALEDIR@
  

2. aclocal.m4

  The aclocal.m4 file uses the aclocal.m4 macros from the
  gettext-0.10.39 distribution.

  The default has been changed to NO nls support:

   ORIGINAL:
      AC_ARG_ENABLE(nls,
        [  --disable-nls           do not use Native Language Support],
        USE_NLS=$enableval, USE_NLS=yes)

   NEW:

      AC_ARG_ENABLE(nls,
        [  --enable-nls           use Native Language Support],
        USE_NLS=$enableval, USE_NLS=no)

  You can do this by the following steps:
     
       cp aclocal.m4 aclocal.bak

       edit aclocal.m4 and truncate it at the start of the NLS macros
       ....
          #  NLS Support
       .... (truncate after the comments)

  concatenate the new gettext aclocal macros to the end
     of this file:

       cat .../gettext-xxx/aclocal.m4 >>aclocal.m4

  Edit the new aclocal.m4 and change:

      AC_ARG_ENABLE(nls,
        [  --disable-nls           do not use Native Language Support],
        USE_NLS=$enableval, USE_NLS=yes)

      to:

      AC_ARG_ENABLE(nls,
        [  --enable-nls           use Native Language Support],
        USE_NLS=$enableval, USE_NLS=no)
