Today, I installed a very nice utility to generate LOC statistics for my code - sloccount. Every time I run this tool, I got following message: perl: warning: Setting locale failed..
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
LANGUAGE = "pl_PL.UTF-8",
LC_ALL = "",
LANG = "pl_PL"
are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
This message clearly says I don’t have LC_ALL set with appropriate value. So, I did not think too long and run tried to set it:
$ export LC_ALL=pl_PL.UTF-8
and checked if everything is OK, and it wasn’t:
$ locale
mloskot:~$ locale
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory
LANG=pl_PL.UTF-8
...
Hmm, strange.
I googled a bit and I found I need to reconfigure my locales. First, I had to install localeconf because I it wasn’t installed:
$ sudo apt-get install localeconf
Then, I was able to reconfigure locales on my box:
$ sudo dpkg-reconfigure locales
$ sudo dpkg-reconfigure localeconf
I answered questions asked bo configuration wizards with checking all boxes next to LC_CTYPE, LCMESSAGES, and other customizable LC* variables, just only to be sure they will be exported.
After these steps, I run locale command, but LC_ALL= was still listed as empty variable, so I added following line to the $HOME/.bash_profile file:
export LC_ALL=pl_PL.UTF-8
Now, all locales are exported properly and I don’t get any error or warning message from Perl scripts. I just wonder why LC_ALL is not set during installation by default.
