Enabling Language Translation on Your System
In order to properly manage translations, openDCIM utilizes the standard open source utility called Gettext.
To ensure that you have GetText installed on your system correctly, run the following command:
$ echo "<?php error_reporting(0); print phpinfo(); ?>" | php | grep "GetText"
You want a response of:
GetText Support => enabled
If not, you'll need to search your particular distribution's documentation for how to install GetText both at the system level and to enable it within PHP.
Important note! If you wish to interact with the template repository, you must install en_US.utf8 locale on your system, as all templates are in that format.
A dependency of Gettext is that the locale for the language that you wish to support must be installed on your server. This is basically a mapping of the character sets so that extended characters may be displayed properly.
See what locales are currently installed on your system:
$ locale -a C C.UTF-8 en_AG en_AG.utf8 en_AU.utf8 en_BW.utf8 en_CA.utf8 en_DK.utf8 en_GB.utf8 en_HK.utf8 en_IE.utf8 en_IN en_IN.utf8 en_NG en_NG.utf8 en_NZ.utf8 en_PH.utf8 en_SG.utf8 en_US.utf8 en_ZA.utf8 en_ZM en_ZM.utf8 en_ZW.utf8 POSIX
Above is the output on an Ubuntu system installed for English. You'll noticed that other than POSIX and C, only en_ prefix locales are present.
If you wish to install another locale, such as Traditional Spanish (es_ES), you would do the following:
$ sudo locale-gen es_ES.utf8
The postfix of .utf8 is important as that is the character encoding we use for internationalization. If you simply installed the es_ES locale then some characters may not display correctly.
