QT4.8 software used to be a huge effort to build, not willing to throw away. Reinstall Qt4.8 Version
1. Install Qt-creator
Install Qt-creator-win-opensource-2.4.0.exe version, not recommended to use the latest version 4.0
2. Install QTSDK
# Install Qt-creator-opensource-windows-x86-4.0.0.exe version to use PCL library
Install Qt-opensource-windows-x86-vs2010-4.8.6.exe version to use PCL library
3. Association-Configuration Building Tools
Creator is not able to build the 4.8 version of the project for the time being, requiring compiler affinity. Find the build and run in the tools-options:
QT Version Select the Qmake under the installation directory, the directory is C:\qt\qt4.8.6x86vs10\bin\qmake.exe, do not select the wrong location
Tool chains can be automatically detected
4. Build QT Project

Common errors:
For users who do not have VS2010 installed, you may need to install the VC + + 2008 Redistributable-x86 installation package, you need to download the Microsoft website.
Reason:
Unable to open include file: "Qmainwindow" is because QT5 can not compile QT4.8 project at this moment;
Unable to compile QWT6.0, also the second reason.
