I want to run a Baka-MPlayer (a QT application) with another language (Dutch). I tried doing LANG=nl_NL.UTF-8 ./baka-mplayer, but it didn't work. My current LANG variable is set to en_GB.UTF-8 When I type in LANG=nl_NL.UTF-8 locale, it gives an error that the locale isn't installed.

    More info is needed, but if you mean changing temporarily the system language so that the application detects a different language in the system if it requests it, then your answer might be here askubuntu.com/questions/142812/… – MyUserIsThis Jan 18 '16 at 14:19
  • @MyUserIsThis: Actually I think the OP may have provided sufficient info. It's a well known problem that some qt applications don't interpret the locale correctly. – Gunnar Hjalmarsson Jan 18 '16 at 15:43
  • Furthermore, I don't think this is a duplicate of question 142812. If at all a duplicate, I'd rather suggest askubuntu.com/questions/447454/… – Gunnar Hjalmarsson Jan 18 '16 at 15:54

Some qt applications use (incorrectly) the LC_NUMERIC locale category to pick the display language. Hence you may want to try:

LC_NUMERIC=nl_NL.UTF-8 ./application

Or, if that doesn't work either, try:

LC_ALL=nl_NL.UTF-8 ./application


When seeing the additional info after you edited the question, it looks like you haven't installed the Dutch language. You'd better do so using Language Support.
