« on: April 04, 2005, 11:31:09 am »

Hi,

I want to try to cross-compile this library, in order to cross-compile my application that is using a thread.
Where is it possible to find the sources file ?

Thanks,

Linux Issues / Qtpoia SDK problems

« on: April 02, 2005, 09:23:56 am »

Hi,

I have to use a thread in my application written in qt, and I'm changing it to qtopia 1.7

if i write : CONFIG += qtopia warn_on release
in my gpus.pro

I've got this error :

MyThread.h:5: error: erreur d'analyse syntaxique before `{' token

#ifndef MYTHREAD_H
#define MYTHREAD_H
#include <qthread.h>

class MyThread : public QThread{
 
 public:
  virtual void run();
};

#endif

--> I think it doesn't find qthread.h

---------------------------------------------------------------------------

if if i write : CONFIG += qtopia warn_on release thread
in my gpus.pro

I've got this error :

Thanks TimW,
I have no more the problem after have erase thread from gpus.pro.

But, I've got one more problem, but I think it's a problem of understanding .
Indeed, I've got a gpus.ui and I want to include gpus.h in my main.cpp.
gpus.h is created by qt,.

I hope you understand my problem of comprehension in order to explain me how I can do this.

don't forget that I put my code in a precedent answer.

Thanks,
Matthieu.

Hi everybody,
I put up this topic because it is really interesting.
I've got a question to all of the persons which understand this topic.

I post the code a this application, I've got an erroer during the compilation.

Qt/Qtopia / Difference Between Qtopia And Qt/embedded

« on: March 30, 2005, 05:47:38 am »

On trolltech site, you've two major libraries : QT and QTopia

when you click on QTopia library, you've got the list of the class present in this library.
But on the page of Qtopia, there is a poinetr to QT/embedded, which has mroe classes than QTopia.

I don't understand the difference between qtopia and qt/embedded.

Qt/Qtopia / Qt Designer3 -> Zaurus

« on: March 30, 2005, 02:02:28 am »

A quick solution might be to flash your Zaurus with pdaxrom which gives you X and qt3, and for which you can easily cross compile or natively compile a qt application....
[div align=\"right\"][a href=\"index.php?act=findpost&pid=72758\"][{POST_SNAPBACK}][/a][/div]

ok so if I flash my Z with pdaxrom.
How can I compile mon qt application ?

I post my code here.

PS : I'm a student wich have to do a project. So I don't have the Z, but my teacher can update it if necessary.
So I don' t really have the possibility to test the result of a cross-compiling.

Qt/Qtopia / Qt Designer3 -> Zaurus

« on: March 30, 2005, 01:19:45 am »

Hi,

iamasmith is right, it's exactly what I want to do.

I made all my application, I've got .cpp .h files and now I want to cross compile all of this in order to use the application on a zaurus.

In fact, I'm a newbie in programming for zaurus, and I didn't really known the difference between qt2 and qt3.

So I took qt designer3, I've to put it on the zaurus for tomorrow, so I'm a little speed.

My code is really simple. I use a qprocess, because I have to do some snmp requests, and only qt 3 is compatible with this.

Is there anybody able to cross-compile some code written in qt3 for a zaurus ?

Thanks,
Matthieu

Hi,

I'm a newbie in zaurus programming.
I wrote a little program with qt designer3, it turns under linux and now I want to put it on a zaurus c760.
How can I make it easy ?

Thanks a lot,
