I will teach you how to port konqueror (1)

KonquerorMany people use it. It is much better than some browsers. This article will teach you how to port konqueror.

1. Compile the QTE Library

Generally, If You Want To develop Qt/Embedded, you 'd better compile Qt/Embedded into two versions: the host version and the target version.

2. After obtaining the source code of Qt/Embeded, decompress it to two directories respectively.

3. Compile the host version

1) export environment variable

Export QTDIR =/usr/local/qtopia/work/qt-2.3.5

Export QTEDIR = $ QTDIR

Export PATH = $ QTDIR/bin: $ PATH

Export LD_LIBRARY_PATH = $ QTDIR/lib: $ LD_LIBRARY_PATH

2) Run./configure

./Configure-depths 16.32,-no-ipv6-no-cups-no-pch-qvfb

3) Compile the Qt/Embedded function library

Make sub-src

4) Compile Qt/Embedded auxiliary development tools

Cd tools; make

In this step, a uic command that can be run in the host environment (x86) is placed in the $ QTDIR/bin directory.

In this case, you can use the qvfb tool provided by qte to run the example in examples in the qvfb window.

4. Compile the target version

First install the cross-compilation tool

Qte version is qt-2.3.5

Because I am using a PXA255 board, the touch screen driver is inconsistent with the touch screen interface in qt-embedded.

You must modify src/kernel/qwsmouse_qws.cpp in the qte directory.

Add a member variable unsigned char prevstate when defining the QCustomTPanelHandlerPrivate class.

The modified class definition is as follows:

Class QCustomTPanelHandlerPrivate: public QWSMouseHandler {

Q_OBJECT

Public:

QCustomTPanelHandlerPrivate (MouseProtocol, QString dev );

~ QCustomTPanelHandlerPrivate ();

Private:

Int mouseFD;

Unsigned char prevstate;

Private slots:

Void readMouseData ();

};

Then modify the member function readMouseData.

To:

Void QCustomTPanelHandlerPrivate: readMouseData ()

{

If (! Qt_screen)

Return;

CustomTPdata data;

Short data2 [4] = {0 };

Int ret;

Ret = read (mouseFD, data2, sizeof (data2 ));

If (ret ){

Data. status = data2 [0];

Data. xpos = data2 [1];

Data. ypos = data2 [2];

QPoint q;

Q. setX (data. xpos );

Q. setY (data. ypos );

MousePos = q;

If (data. status &&! Prevstate ){

Emit mouseChanged (mousePos, Qt: LeftButton );

} Else if (! Data. status & prevstate ){

Emit mouseChanged (mousePos, 0 );

}

Prevstate = data. status;

}

If (ret <0 ){

QDebug ("Error % s", strerror (errno ));

}

}

Then compile qte

The compilation script is as follows:

#! /Bin/sh

Export QTDIR = 'pwd'

Export CC = arm-linux-gcc

Export AR = arm-linux-ar

Export NM = arm-linux-nm

Export RANLIB = arm-linux-ranlib

Export CXX = arm-linux-g ++

Export LINKER = arm-linux-g ++

Export STIRP = arm-linux-strip

Export OPTIONS = "-DQT_QWS_IPAQ-DQWS-dno-exceptions-fno-rtti-pipe"

Make clean
