Hi,

We will develop with my friend a program with C++/Qt and we will sell it (commercial). The application will work cross platform. We have some questions:

1) Which company (nokia...) develops the Qt as free for commercial use? Are The supported platforms (operation systems) less than the others? I mean is there any difference of these Qt?

2) Which IDE (free for commercial with QT/C++ entegration plugins) do you suggest for Linux? If I will write a code on Linux, I will use different IDEs to compile the code for different operation systems? If yes which IDEs do you suggest for other operation systems just for compiling the code?

2) This is little bit stupid question but I will ask it to be sure. C++ (with it's standart libaries) lincence is free for commercial use?

Thanks in advance
