How can I set up my environment for building Qt/Qt applications with MinGW?

In order to build Qt with MinGW, then follow these steps:

1) Download MinGW from our ftp site. There is a link to it in the compiler notes here [doc.qt.nokia.com]

The patched version is a version with more support for DirectShow. That is required if you want to build the phonon DirectShow backend, if you don’t need to build that we require mingw-gcc 4.4 or up as a compiler.

2) Download the qt-everywhere-someVersion.zip package

3) Open a command prompt by typing

  1.  cmd
in Run/Search in the Start Menu

4) Set up the environment as follows in this command prompt:

set PATH=yourPathToMinGW\bin;PATH set INCLUDE= set LIB= set QMAKESPEC=win32-g++

and then type

  1. configure -anyOptionsYouWant && mingw32-make

in this command prompt

5) When building Qt applications, add yourQtVersion\bin to the PATH environment variable like:

  1.   set PATH=yourQtVersion\bin;%PATH%

I followed these instructions to compile qtbase from here – git://gitorious.org/qt/qtbase.git with mingw that comes with qtcreator 2.3 but i get these errors
