Can't build a "Hello World" Qt application

[craigugoretz]

I have a Netbeans project that displays a blank form to the screen. When I go to build and run it, I get these error messages:

"/usr/bin/make" -f nbproject/Makefile-Release.mk QMAKE=/C/Qt/4.6.4/bin/qmake.exe SUBPROJECTS= .build-conf

BUILD FAILED (exit value 2, total time: 2s)

By the way, when I create a console "Hello World" application using Netbeans, it builds and runs just fine. When using Qt, however, there seems to be a file locking issue (as my best explanation of the phenomena).

Craig,

It looks like the file QtApplication_2.exe is open while you are trying to build it. I would look in the Task Manager for a process by that name.

Thanks,
DCM
