Cross-compile the target machine version of QTE and qtopia (by onebyte)

[Compiling environment Note:]

The Linux operating system of the host machine is fedro core 5.

Tool chain version: Arm-Linux-G ++ 2.95.3,

Host compilation tool chain GCC version 4.1.0

QT-X11 version 2.3.2

QT/e 2.3.7

Qtopia version 1.7.0

(1) Compile QT-X11

• Decompress qt-x11-2.3.2.tar.gz and change the decompressed folder name to qt-x11.

• CD qt-x11

• Change the src/tools/qvaluestack in the qt-x11 folder. h 57th line source code remove (this-> fromlast (); for this-> remove (this-> fromlast (); otherwise, [XML/qxml. o] Error

• Create a set-env file

  Export qtdir = $ pwd

  Export Path = $ qtdir/bin: $ path

  Export manpath = $ qtdir/doc/MAN: $ manpath

  Export LD_LIBRARY_PATH = $ qtdir/lib: $ LD_LIBRARY_PATH

  Echo Yes |./configure-no-xft-no-OpenGL-no-Sm

  Make

• In this folder, run the "source set-env" command (there is a space between. And set-env)

(2) Compile the qte-2.3.7 of the target machine version

• To compile qtopia, copy the./src/QT/qconfig-qpe.h under the qtopia folder to the src/tools/

• Then create the set-env file.

  #! /Bin/bash

  # Compile a QTE script

  # $ PWD indicates the folder where QTE is located.

  Export qtdir = $ pwd

  Export qtedir = $ qtdir

  Export Path = $ qtdir/bin: $ path

  Export Path =/usr/local/ARM/2.95.3/bin: $ path

  Export LD_LIBRARY_PATH = $ qtdir/lib: $ LD_LIBRARY_PATH

  Echo Yes |./configure-platform linux-x86-g ++-xplatform Linux-arm-G ++-qconfig qpe-Depths 16,24, 32

  Make

• Run "source set-env"

• Note that in configure, you must specify platform and xplatform, and set platform to linux-x86-g ++, otherwise when using Linux-generic-G ++, find the default g ++ path of the current system. Because the new G ++ path is set in the path, an error occurs.

• To be transplanted to the target machine, run $ qtedir/lib/libqte. so. x. y. copy Z to the Lib folder on the target machine and name it/lib/libqte. so. X (based on the preceding libqte number );

  Copy $ qtedir/lib/fonts/fontdir to the installation path of QT/E on the target machine (by setting $ qtdir on the target machine ), for example,/usr/local/Qt-embedded/lib/fonts/fontdir

(3) Compile the qtopia-1.7.0 of the target machine version

• When compiling qtopia, you need to use the UIC command of QTE to explain the related resources, copy the UIC command in the bin directory of the compiled qt-x11 to qtedir/bin.

• Create a set-env file:

  #! /Bin/bash

  # Install qtopia

  Export qpedir = $ pwd

  # The qtdir here is the QT/e path compiled earlier.

  Export qtdir =/friendly-arm/ARM-qtopia/QT

  Export qtedir = $ qtdir

  # Set the location of the tool chain on the local machine according to your personal situation

  Export Path =/usr/local/ARM/2.95.3/bin: $ path

  Export Path = $ qtdir/bin: $ path

  Export Path = $ qpedir/bin: $ path

  Export LD_LIBRARY_PATH = $ qtdir/lib: $ LD_LIBRARY_PATH

  CD./src

  Echo Yes |./configure-platform Linux-arm-G ++

  Make

• Run "source set-env"

• If you want to port data to the target machine, bind, apps, etc, plugins, services, sounds, i18n, Lib, pics, copy the help folder to qpedir on the target machine (by setting qpedir)

• Create the qtopia script file in the bin directory of the target machine (as shown below)

  #! /Bin/sh

  Export set home =/root

  Export set qtdir =/opt/QT

  Export set qpedir =/opt/qtopia

  Export set qws_keyboard = "USB:/dev/input/event1"

  Export set qws_mouse_proto = "USB:/dev/input/mouse0"

  Export set Path = $ qpedir/bin: $ path

  Export set LD_LIBRARY_PATH = $ qtdir/lib: $ qpedir/lib

  $ Qpedir/bin/qpe>/dev/null 2>/dev/null

• After the target machine is started, qtopia can be directly started.
