Detected locale "C" with character encoding "ANSI_X3.4-1968"

Hello! In my own Linux image I try to start any Qt app. But I get warning

Detected locale "C" with character encoding "ANSI_X3.4-1968", which is not UTF-8.
Qt depends on a UTF-8 locale, but has failed to switch to one.
If this causes problems, reconfigure your locale. See the locale(1) manual
for more information.

But if I do

export LC_ALL=en_US.utf8 && ./myapp

Then works without warning. How to ask Qt to switch to en_US.utf8 by himself? May be set something in my toolchain_cross.cmake file? I use it to build Qt from source code...

@DungeonLords You should rather change your locale to UTF-8. This should actually be the default with most Linux distributions. What Linux distribution do you use.

You can check what locale is configured on your system using "locale" command.

this is the output of the locale command. i guess my locale is utf8. why am i still getting this error: configure: error: Detected locale "C" with character encoding "ANSI_X3.4-1968", which is not UTF-8.
Qt depends on a UTF-8 locale, and has switched to "C.UTF-8" instead.
If this causes problems, reconfigure your locale. See the locale(1) manual

why am i still getting this error

Looks like Qt does not support C.UTF-8.
How did you install Qt?
