Error AFTER success

[ceh2624]

I wonder, has anyone seen this before? I just installed Qt 5.3.2 on my desktop PC: Kubuntu 14.0.4. I created a very simple GUI application: one push button and one label for 'Hello World'. When I tried to build it I got two issues as follows:
@:-1: error: error: all: No such file or directory
:-1: error: [first] Error 1
@

The funny thing is that the executable was correctly built except that it will not rum from within Qt. When I run it from the Dolphin file manager or from a bash prompt, it runs perfectly.

Any Ideas?
