QT QNX Installation , refer my other repository
https://github.com/varghes/BeagleboneBlack-QNX-QT

Compilation : (on Windows )

1. open command line  "Cmd"
2. "cd" Change directory to the application directory (.pro )
3. qmake -spec unsupported/qws/qnx-armv7-g++
4. make



Debugging

1.Create Debug version of application
 .pro file  add this on Top

 CONFIG += qt warn_on debug
    debug {
        TARGET = myappdebug
    }
    release {
        TARGET = myapp
    }

2. qmake -spec unsupported/qws/qnx-armv7-g++ CONFIG+=debug
3. make CONFIG+=debug


QNX IDE Changes For Debugging

1.debug configuration-> Environment variable
add this environment variable
 TMPDIR=/ramdisk
 XDG_CONFIG_HOME=/ramdisk

2.compile using commandline , Debug using IDE


 .build File Changes

 1. Copy the executable file to
    prebuilt\armle-v7\sbin
 2. make the script file changes

beaglebone black - QNX QT

           
                  Unlike Raspberry ,beaglebone (AM335X) has a very good documentation , also it has got a very good SDK support which makes porting to any OS is like a cake walk. 
QNX support is already there for this board. only problem is display wont work . It has got some hdmi code , probably thats for some old beaglebone version.  

If you use LCD Cape , please use the original code from QNX site . My focus is only on HDMI & QT .I dont have LCD Cape.

If you want to learn QNX  / If you want work on QNX for the first time, buy this board & use this  BSP ,it has got all the drivers plus graphics /QT support. beaglebone board price is 55$ something last time when I checked. I hate buying bsp from third party vendors, we are paying for QNX , so bsp should be  free , or use the board/processor which has the free bsp support.

Source Code 
                 
         Source code is maintained here 

            https://github.com/varghes/BeagleboneBlack-QNX-QT

Setup :

Test the board and SD Card First:
        Write any working Linux image to the sd card &  hold the boot button(boot from SD card) , power on , make sure you can see the serial debug messages . 

QT Installation :

              Installation files are here . 

               https://drive.google.com/open?id=0B02sL8YIqsjCNS1ZWFNkQzRRY0E

this was there in the QNX site.. but now the link is removed  (qt_qnx_2011-02-24b.zip) , they might have thought QT support is beyond their scope. So I have uploaded here in my google drive.  qt got lgpl license. which is fine for distribution.

1. unzip it ... Installation folder contains files for different OS , mine is windows. If you are using linux /other OS use the correct folder.

2. qt_qnx_host_win32_x86 goes to  C:\QNX650\host (mine installed here) , just copy the files only 
    dont copy the  folder /replace the folder 

 qt_qnx_targets\target\qnx6\armle-v7  (both bin & lib also copy the qt4/pkgconfig folder )goes to  
C:\QNX650\target\qnx6\armle-v7

qt_qnx_targets\target\qnx6\usr goes to C:\QNX650\target\qnx6\usr


 Build QT Project :

1.Open The QNX IDE -> File ->New -> QNX C++ Project -> 
     build variants -> armV7 

2.Test application code 

#include <qt4/QtGui/QApplication>
#include <qt4/QtGui/QPushButton>
#include <stdio.h>
#include <cstdlib>
#include <iostream>

int main(int argc, char *argv[]){
printf("Application Running... ");
QApplication app(argc,argv);
QPushButton Button1("Hello World");
Button1.resize(180,90);
Button1.show();
return app.exec();

}

3. Right click on the project -> properties  , check build variants

4. Select Compiler Tab ->  Extra Include path 

Add from -> "Disk"  -  then "apply "

[QNX Directory ] /target/qnx6/armle-v7/usr/lib/qt4/imports
[QNX Directory ]/target/qnx6/armle-v7/usr/lib/qt4/plugins
[QNX Directory ]/target/qnx6/usr/include/qt4

5. Linker Tab 
category  "Extra library  "  click "Add"     and type
            QtGui
            QtCore
click "apply "  , click "ok"   , Now "build project" can compile the QT source code.

qnx executable image can be found here  , in the project folder . arm\o-le-v7

.build scripts changes 

 BSP files are here  ... as usual 
a. unzip it  b.create an empty project c. File -> import ->General ->Existing Projects in to Workspace -> File system (select the unzipped folder ) -> build

libQtGui.so.4 , libQtCore.so.4 both are the main libraries  , I have included other libraries to test the qtdemo ,designer , browser  applications
Script changes, Project settings are already done in the BSP  & Example QT project  , So you dont have to make any changes.

if build is successful , you should be able to see the final image 

First QT application should be followed with the command "-qws"
example 
qt_v7_demo -qws &

This window will become desktop window .


Flashing SD Card 

"ifs-ti-beaglebone.bin  " before adding the QT files the the image size was around 15 MB only ..
After QT library additions it becomes 75MB .. if you use the 2 core QT Libraries , you can reduce the image size.

boot files are here 

https://drive.google.com/open?id=0B02sL8YIqsjCWlpRWVVTVWpkZ00

TI_SDCard_boot_utility_v1_0.exe   you can use this tool to copy MLO file  .. under windows 10 ,"run as administrator" mode  .. if you have any issues, use Windows XP ,VMware virtual machine .

If it works , you should be able to see the serial debug message . uEnv.txt usually  directs the control to SD Card automatically .  if doesn't work , while powering ON , hold the boot button( next to usb B connector )
