Qt quick guide. used to run polyline simplication program.

Qt (version 4.7.4) is installed under C:\Qt\4.7.4 on my XPS-15 laptop.

the demo from cp is under C:\Demo_MFC\psimpl_v7_win32_demo.

The demo application was made using Qt 4.7.3, Qt Creator 2.1.0 and Visual Studio 2008 Express. Complete source code is included.

4. Qt correct setup for QMAKESPEC, QTDIR and PATH

When you want to use different configurations for different platforms in your .pro file, it’s necessary to correctly setup three variables: QMAKESPEC, QTDIR and PATH.

Hi I have recently downloaded qt 4.7.3 for windows qt-win-opensource-4.7.3-vs2008.exe from this Link , I was using Qt Creator 3.0.1 based on Qt 5.2.1 (MSVC 2010, 32 bit) till now , but I need to build my project in Qt 4.7.3 ...the problem is I couldn't find the Qtcreator.exe in the downloaded folder , it contains all the libraries and everything except the.exe file .Is there any solution to get the Qtcreator.exe file for Qt 4.7.3 or is there any way to configure it with my Qt creator 3.0.1?

6. How to Set New User and System Environment Variables in Windows

Environment variables are a set of dynamic named values that can affect the way running processes will behave on a computer. The variables can be used both in scripts and on the command line. Environment variables makes it easy when certain standard directories and parameters need to be referenced but where the actual locations or names can vary from computer to computer.

10. Setting environment variables for build in Visual Studio (2008)

I looked at some projects generated by the Qt plugin for VS and noticed that they use the environment variable QTDIR to refer for example to the Qt header files. However I failed to figure out where this variable is set. I guess it must be somewhere in the project settings, however I could not find it. Also please note that I am referring to the environment variables required during the build, not the ones for debugging.

11. Documentation for setting environment variables in windows?

Hi, I've been having tons of issues with the latest Qt release(which can be seen in my post history) and i'm trying to tackle the next issue by setting environment variables. Is there documentation that tells me how to set them properly? cause Qt is complaining that they need to be set..

12. Qt tools: Environment Variables

In order to successfully use Qt three environment variables have to be setup: QTDIR, PATH and QMAKESPEC. In order to compile Qt, the QTDIR has to be set to point at the directory containing the Qt distribution. In my Mandrake 9 installation QTDIR is set to /usr/lib/qt3. To be able to invoke the Qt tools from the command line the PATH variable needs to be set. Simply include ${QTDIR}/bin at the end of your PATH. In order to use qmake properly the QMAKESPEC has to be setup. QMAKESPEC points at a directory holding files describing the target environment to qmake. Qt includes a directory called mkspecs, located at $QTDIR/mkspecs, containing a number of prepared specifications. Hopefully one of these fits you needs, for example an x86 Linux installation using gcc as the compiler uses linux-g++, thus QMAKESPEC should be set to $QTDIR/mkspecs/linux-g++.
