Build Your Qt Project on Windows and Mac OSX

Why i needed to build my app on another platform?

I’ve used Qt just for its cross platform-ness indeed its “code less and do more ” paradigm is apt  so there were hinderances in using MinGW compiler to build my project targeted to windows platform, below is the listed procedure and screenshots

Its a 2 Stage Process, Installing Libraries and building your project

Working on Microsoft Windows 7 and Mac OSX Snow Leopard

*Note: Phew Dont Worry its very simple, ive just added some information, so it looks little long

Procedure:

Prerequisites:

  1. mingw-get-inst
  2. Qt libraries 4.8.2 for Windows (or Higher Version)
  3. Your .proj file (Associated .ui, .cpp, .h etc)

STAGE 1: Setting up the environment

Step1:Download and install mingw-get-inst

Get if from here
You would need this as in Qt libraries installation it will ask you for the g++ component

Do select

  • C Compiler
  • C++ Compiler
  • MingW Developer Toolkit

Step2:Download and Install Qt libraries 4.8.2 for Windows

  1. Goto : http://qt.nokia.com/downloads
  2. Scroll down to Qt Library
  3. and choose your version

*Choose with minGW*

ex:Qt libraries 4.8.2 for Windows (minGW 4.4, 318 MB)

You Can get the above file from here

and finish the installation in case if it asks you for g++ component , point to the MinGW/bin folder you just installed in step1

Step4:Setting Up Environment Variables

In User variables create

Variable                 Value

QMAKESPEC          win32-g++

QTDIR                      C:\Qt\4.8.2

*The above value is the  location where you installed your version of Qt

Next: Set the Path Variable

add this

C:\MinGW\bin;C:\Qt\4.8.2\bin;
*They are locations where you installed MinGW and Qt respectively

STAGE 2: Make and Build Project

Step1:Goto Start > All Programs > Qt by Nokia v4.8.2 (MinGW OpenSource)>Qt 4.8.2 Command Prompt
Now you can put your folder containing .proj file (Associated .ui, .cpp, .h etc) in one folder and placethem in C:\Qt\4.8.2
In the Screenshot the folder where my project files reside are in Galaxyand Galaxy.proj is the project file
Now go to the Galaxy Directory as cd Galaxy

Step2: Make

qmake -o Makefile Galaxy.pro

Step3: Build

mingw32-make -f Makefile.Debug

Now Within Galaxy Folder you have Debug and Release where your executable .exe file resides

Now Enjoy Making Projects on Mac OSX and Easily Deploy on Windows too

Here are the screenshots for my prototype apllication in windows and OSX

*Censored as it is a Coveted Project :D *

Deployed on  Mac OSX (Project Written and Built Initially):

Solution for Pointer Content Bug in Netbeans 7.1

Using Netbeans 7.1

I had a pointer variable declared as

int **nodes

As program continued ,i allocated size on the fly and at a point i needed to watch the contents of this pointer (as an array of values)

The watch pane of Netbeans does not reflect the values

SOLUTION:

Create a watch with  *nodes@22

where you want to watch  all the values in nodes[22][]

Attached Screenshot for reference

in the picture 1st three rows reflect the bug

and post that row is the solution ! Happy Debugging!!!!

Note: For n00bs , you can add a Watch in Variables too !!! :D

‘Nan’ Can Cripple You and your Code

NaN- Not a number is one such night mare that can cripple your entire Code , your hours (Or even Minutes ;) ) of punching the keyboard , that almost teases your patience of debugging the program

Only oneTIP for this : How certain you are about your code and how perfect is your code analysis and Data flow is ,

Just Check for Division By Zero Evaluation!

In any Division Arithmeticity Do check this , keep it as a habit and it should just flow when you are busy in such Divisional Logics in your code

The dirty way is to add a very small (negligible) padding to your denominator , Sure you woudnt do that if your coding for a Nuke Reactor or NASA JPL Mars Program ;)
