qtcreator is Qt development IDE, install only this is not enough, because there is no relevant Qt library does, that he is just an empty shell, generally do not have access.
qt version is divided into windows, linux, mac versions, each running on different platforms sheets, and in qt5.9 previous, windows version has broken a number of versions, including MinGW and MSVC , which use the MSVC compiler VS , also you need to install some of the Visual C ++ libraries What, in short, if your computer does not VS installed then do not install this version, otherwise use the compiler pass. And we have to use is MinGW version, note that the compiler is only 32, so looking for 64 students do not find the. Some are used for Android development, I do not know, but it would not open ah, as to what the compiler GCC, G ++ and the like, do not understand, MinGW seems to be based on the G ++.
Then talk about the future qt5.9 version, in fact, is integrated, it in previous versions of some of the segments are integrated into an installation package, you can see from the previous installation package becomes a 1.2G 2.3G. The specific segments would put the choice to install a different version of MinGW and MSVC, etc. For example, before you can choose when to install, and windows version is integrated into qt-opensource-windows-x86-5.9.0 in.
