QT versions, kits and compilers

Question

I am new in QT and was wondering what is the difference between QT versions, kits and compilers. In my \"Build & Run\" tab are avilable:

Kits:

• Desktop

Answer 1

Qt versions are Qt packages that you download from digia (libraries, source code, documentation, etc...), compilers are the compilers you have on your machine and kits are valid combinations of these two.

In your case you have:

• Qt 5.4.2 64bit
• Qt 5.5.0 64bit
• Msvc both 32bit and 64bit

you can combine the two Qt versions (that are 64bit) with the 64bit version of the msvc compiler, but not with its 32bit version.
