Problem with compiling

[jeanrl]

Hi people!

I'm new user QT-Creator, but i'm programer have 20 years in varibles linguagers.
I am having trouble compiling the program for example musicplayer. Compile output:

Error while building project capabilities
When executing build step 'Make'
My SO is Windows Vista and my version of QT-Creator is 4.5.
I am thinking of migrating to QT, but must first resolve these problems, so need help from you.
Thank's

hm, i am not a programmer, but it looks like phonon is missing. Therefore your source does not compile on windows.

[jeanrl]

But I did the complete installation, then imagine what he must have also installed the libraries of the phono.
Like I said before, although be programmer I never used the QT, then I'm totally lost.
Thank's.

Hi, have a look at installing phonon:

Warning: The MinGW version of Qt does not support building the Qt backend.

What about this? Does it work anymore?

I had already installed the DirectX SDK, but I had just only given the command
"config ...-phonon", then yesterday applied the command "make" and despite 2 hours after he submitted 2 errors when I returned to run the example musicplayer it came to running, but without running their functionality such as file upload audio featuring the message: WARNING: bool Phonon:: FactoryPrivate: createBackend () phonon backend plugin could not be loaded.
Still do not understand the reasons, things are still very confusing to me yet.
I need to use the phonon multimedia functions or it is a framework and I use if you want and do not want I use the multimedia functions right?
Thank's
