    [quote author="chethan7845" date="1384232456"]am getting error while compiling my code...[/quote]Hi, please describe the error and post the error messages. Otherwise, it is hard to help you.

    Is this for a new project? If so, I recommend installing "Qt 5.1.1":http://qt-project.org/downloads instead.

    [quote author="Rahul Das" date="1384237535"]See this "Wiki":http://qt-project.org/wiki/Building_Qt_5_from_Git[/quote]The OP is asking how to get started with using Qt. That wiki isn't going to help.

        In the wiki, you can find the dependencies Or the additional packages.

        It is not mandatory to use the "QtSDK":http://doc.qt.digia.com/sdk-1.2/index.html . For Ex : You can use Qt plugin with IDEs like Eclipse , Or VS, as long as the Qt libs and tools are in place.

                  Finding fatal errors such as “fatal error LNK1181: cannot open input file ‘qtmaind.lib’ “[/quote]Your DLLs have gotten mixed up.

                  Do this:

                  Uninstall all versions of Qt from your computer

                  Make sure you don't have Qt in your PATH

                  Make sure you don't have MinGW in your PATH

                  Go to http://qt-project.org/downloads and download "Qt 5.1.1 for Windows 32-bit (MinGW 4.8, OpenGL, 666 MB)"

                  [quote author="Rahul Das" date="1384238982"]It is not mandatory to use the "QtSDK":http://doc.qt.digia.com/sdk-1.2/index.html .[/quote]That is the Nokia SDK. It is obsolete. Do not use it.

                      Hi chethan7845,

                      Please post your question in a new thread. It is completely unrelated to this one.
