Running app on Embedded Linux

[coolguy]

Hi,

I have developed an Qt application using Qt creator in Linux(ubuntu) and compiled it successfully. Now I want to run the same application on another linux/windows/embedded device. I have tried doing it for embedded device. I have downloaded the Qt libraries 4.7.3 for embedded Linux (204 MB) from the link http://qt.nokia.com/downloads.

Then I started installing it by following the guide lines given at http://doc.qt.nokia.com/latest/qt-embedded-deployment.html

I am trying to build the application statically because my application size is very less (less than 100 KB). I have completed the first step shown below successfully

1. ./configure -static -prefix /path/to/Qt <other parameters>
2. make sub-src

But while executing second step I am getting lot of errors like shown below

./include/QtCore/qatomic_arm.h:131: Error: no such instruction: swpb %al,%d make[1]: *** [.obj/release-static/qabstractanimation.o] Error 1 make[1]: Leaving directory /home/pavan/Desktop/qt-everywhere-opensource-src-4.7.3/src/corelib'
make: *** [sub-corelib-sub_src_target_ordered] Error 2

I have installed the required tool chain (arm-linux-gcc-4.4.3). But still I cannot take things forward.

By google I have understood that I need to compile the application using static libraries or shared libraries to run application on any device.
Is it correct?

The procedure I have tried it it correct? Please let me know how to run application developed on one system to run on another system

What do you mean by

2) make sub-src

You have to "configure" Qt, run "make" and probably to "make install".
These are three steps until you can start to compile your application.

Thanks for your reply. I have just followed the guidelines given in the link at http://doc.qt.nokia.com/latest/qt-embedded-deployment.html

The difference between make sub-src and just make is that the former will build only the Qt libraries and the latter will build the libraries plus examples, demos and so on. The latter takes a lot longer to complete. So it is preferred to use make sub-src

Sorry, I did not read careful enough. I was over-looking that the problem occurs already in the make for compiling Qt.

You should provide the complete configure command.

I could compile qt statically and now I got .exe file. I need to deploy on my embedded linux device (mini2440 board). But I could n't run the file. Please help me out how could I run a simple qt application written using QT Creator on embedded linux device.

Thanks in advance

I am struggling a little with your decriptions.
It is not clear what operation systems are you working on.

What is your host OS?
Where are you running QtCreator?
You like to deploy on a linux device, right?

Again, it would be good to know the complete configure command you have been using.
