Software requirements:

This code is developed on Debian 10.x and should also work on Debian derivatives like Ubuntu and other GNU/Linux distributions.

If you are on Debian or Ubuntu all required libraries should be installed from your distribution. Please do not compile them from source!

Microsoft Windows is currently not supported and I have no plans to do so. If you feel an urgend need to port this code to Windows I would be happy to take patches.

To install the l10n into your database the following steps are requered:

1. Install the libraries for the C/C++ stored procedures

The easiest way to do this on Debian/Ubuntu is to build packages and install them:

make deb

To make this work you will need to install the required libraries:

sudo apt-get install devscripts equivs
sudo mk-build-deps -i debian/control

On other Distributions it should work to use make/make install, given the required libraries listed in debian/control have been installed. I would be happy if somebody would contribute a spec-file for rpm based distributions.

The build process will need to download country_osm_grid.sql from https://www.nominatim.org/data/country_grid.sql.gz If your computer is offline for some reason. Just download this file and put it inside your build directory.

Thai transcript is a seperate extension because it is based on python (https://pypi.org/project/tltk/) and installing postgresql-plpython3 is probably not an option for everybody.

If osml10n_thai_transcript is not installed transcription for thai language will fall back to libicu which will not produce very good results.

To make osml10n_thai_transcript work tltk must be installed on the system level using the pip (pip3) package manager:

sudo pip3 install tltk

2. Load the required extensions into your database

CREATE EXTENSION osml10n CASCADE;
CREATE EXTENSION osml10n_thai_transcript CASCADE;

If you already installed the previous version of this software use:

ALTER EXTENSION osml10n UPDATE;
ALTER EXTENSION osml10n_thai_transcript UPDATE;

WARNING: This will only work from the previous version to the current version, not across multiple versions.

After installing or updating the extension you should be able to do the following:

yourdb=# select osml10n_translit('北京');
 osml10n_translit
---------------
 běi jīng
 (1 row)
yourdb=# select osml10n_kanji_transcript('漢字');
 osml10n_kanji_transcript
---------------------
 kanji
 (1 row)
yourdb=# select osml10n_thai_transcript('ถนนข้าวสาร');
 osml10n_thai_transcript
---------------------
 thanon khaosan
 (1 row)

To check if everything went well run the test script provided in the tests/runtests_in_virtualenv.sh directory. As this test uses pg_virtualenv it is not required to create a database to run the test.
