Fine. "Gadget" then. ;)

@Wieland I mean a self contained compiler+IDE, like that steup Java SDK + Netbeans IDE :D

SGaist

As previously suggested: Qt MinGW version, it includes the compiler

Mnabil

@SGaist That what supposed a cross Operating Systems platform to be

mcosta

@Mnabil I don't agree.

A really cross OS C++ platform should use the standard OS compiler.
We using the same code to build for

Windows (Visual C++)
Linux (gcc)
Mac (clang)
iOS (clang-ios)
Android

In that way you get the best for the native compiler

Microsoft doesn't allow us to include their compiler with the Qt installer. If you want the compiler included, get the MinGW version, not the MSVC version.

@mcosta does that mean I've to have all platforms to compile for them, or I write once and Qt website will compile my project to various Operating Systems?

mcosta

@Mnabil In theory you can also cross-compile using GCC but if you want use the native compiler you have to build in the platform.

I have a Mac with Windows and Linux Virtual machines so I can compile my code for all platform I need

Mnabil

Thank you all for kind help now things running well

Last thing would you please recommend books or resources to depend to move on Qt as much quick as possible, specially in Business/Finance/Mathematical oriented applications

mcosta

Hi,

the only book I know is enough updated is http://qmlbook.github.io/ but is about QtQuick.

pecially in Business/Finance/Mathematical oriented applications

Qt is a generic framework so, once you got some basic skills, you can adapt it to your domain.

Here are two titles form Packt Publishing:

I haven't read them though, so I can't comment on their quality.

Anyway, there are some very good resources online too. For example, a "Getting Started" tutorial from the official documentation: https://doc.qt.io/qt-5/gettingstartedqt.html

Search YouTube for "Qt 5" videos.
