qlocale_unix.cpp line 36 in Qt 4.8 is a comment:


Did you mean line 58?

If this is just an #include issue, try compiling with precompiled headers 
(pass -pch to configure).

QWS was *only* designed for Linux. Do not try to run it on any other platform. 
You should use X11 on QNX instead. The early QPA might work, but we really 
can't recommend it until Qt 5.

You are doing something wrong: trying Qt 4.8 for any new project in 
almost-2018. Please upgrade.

Don't pass options you don't understand. That option is the one that turned 
the Linux-only QWS subsystem on. Remove it and make sure your buildsystem has 
X11 headers.

Or upgrade to Qt 5.
