Hi,

It seems you are using a Qt 4 qmake which probably is the one installed with your system's Qt development package.

Did you take a look into your QtCreator Qt versions ?

This is from the "about" in my Qt Creator GUI:

@Qt Creator 2.7.0
Based on Qt 5.0.2 (32 bit)

Built on Apr 9 2013 at 09:31:06

From revision b6257ef735

Is that what you mean?
Is there another place I can see the versions?

SGaist

No it's not, the version of Qt used to build QtCreator and the one you use to build your application are not related.

Go to Options/Preferences -> Build & Run -> Qt Versions

Ahh.... I see... this makes sense now!, here is what it says:

Auto Detect:
Qt 5.0.2 GCC 32bit /opt/Qt5.0.2/5.0.2/gcc/bin/qmake

Manual:
Qt 4.8.1 in PATH (System) /usr/bin/qmake-qt4

I think you are right, so what do I need to change to make that Qt5?, just point it to the Qt5 path? (where would that be?)

But... I just looked at my working Linux and that is exactly the same :(, except it has a different "manual" version 4.6.2...

Go in the Kits tab and either add a new kit using your Qt 5 or change the current kit to use your Qt 5

code_fodder

Right... so, I have no idea exactly what happened, but this has fixed my issue! :)

What I did was:
Attempted to "Add..." and kit in the build and run menu. Saw loads of options that I did not understand. Then cancelled it. Went back in and saw a new "Desktop" entry under "Manual:". I clicked on new entry again, click auto-detect a few times... Then finally I deleted my new entry.

After that I could not build my project (option was greyed out).

Then I closed and opened Qt Creator and tried again, it came up with the "you need to configure your project" page (like when you get the project with no .pro.user file). I had two options, I check the one that had 5.0.2 in it and un-checked the other.

Then... it all just works! - I have the same kits and versions in my build & run options...
I guess this allowed Qt to update itself or something?

Anyway, here is my build output:
@g++ -c -pipe -Wall -g -Wall -W -D_REENTRANT -fPIE -DQT_QML_DEBUG -DQT_DECLARATIVE_DEBUG -DQT_XML_LIB -DQT_NETWORK_LIB -DQT_CORE_LIB -I/opt/Qt5.0.2/5.0.2/gcc/mkspecs/linux-g++ -I. -Icommsnet -Icommsnet/device -Icommsnet/vocoder -Iconfig -Iif -Irpe -Irtp -ItacChat -Iutils -I/opt/Qt5.0.2/5.0.2/gcc/include -I/opt/Qt5.0.2/5.0.2/gcc/include/QtXml -I/opt/Qt5.0.2/5.0.2/gcc/include/QtNetwork -I/opt/Qt5.0.2/5.0.2/gcc/include/QtCore -I../_out -o ../_out/main.o main.cpp

Ahhh.... I never knew how that happened!, I thought it was an admin guy doing that :o

I will update it now.
Thanks
