Trying to link to Qt 5 on dmd 2.068.0~beta1

[Shriramana Sharma via Digitalmars-d]

Trying to compile the attached program to test DMD 2.068's promised
C++ interfacing capabilities:

$ dmd qt.d -L-L/usr/share/x86_64-linux-gnu -L-lQt5Core -L-lQt5Gui
qt.o:(.rodata+0x40): undefined reference to `QWidget::show()'
qt.o: In function `_Dmain':
qt.d:(.text._Dmain+0x3b): undefined reference to
`QApplication::__ctor(int&, char**)'
qt.d:(.text._Dmain+0x4f): undefined reference to `QApplication::exec()'
collect2: error: ld returned 1 exit status
--- errorlevel 1

Seems like I'm doing something hopelessly wrong. Please enlighten.
Also, please specifically review my hastily put-together argv(string[]
args) function...

I'm using Kubuntu Trusty 64 bit.
