Build fails on Arch Linux

[aakodadi]

Build fails on arch with the following error:

sources/main.cpp: In function ‘void myMessageOutput(QtMsgType, const QMessageLogContext&, const QString&)’:
sources/main.cpp:45:24: error: format not a string literal and no format arguments [-Werror=format-security]

This is with

qt5-base 5.15.2
gcc 11.1.0-1

[tuxmaster5000]

I don't see this problem on Fedora 33 using:
gcc-10.3.1-1.fc33.x86_64
qt5-qtbase-devel-5.15.2-15.fc33.x86_64
So I can't reproduce it.

Thanks. I'll see if I can narrow it down to GCC.

Removed -Wformat -Werror=format-security from the default CFLAGS (system wide) and it works now (You have to start with clean source as they get shoved into the generated src/Makefile)

Working on gcc 11.1 removing those flags
