Qt 4.6.2 build a project

[Robix]

Hello. I have some of latest versions of Qt.
But I need to build a project that have created Qt 4.6.2 several years ago.

How easy build it without errors ?

The easiest way is to get the Qt version it was developed with, or at least a latter version of the same major series.
If you need to build with Qt5, you will need to do some porting.

Cheers,

Thanks.
Porting in this case meaning some automated process or "hand" programming ?

Is there in internet older version of Qt to download? If I find Qt 4.6.2 I can install it together with Qt 5 ?

Depends on the program.
In most cases this involves at least some manual adjusting.

Yes.
