Sharp SL-series Zaurus “Qtopia” Development Start-up Guide

Ver 1.11, February 28, 2003, 12/63

1.1.3. Qt/Embedded / Qtopia Build Environment

Native development for the Zaurus is done using C++ and Qt by TrollTech. Qtopia comes with a virtual frame

buffer (qvfb) so that you can test applications under X11 without having to have a Zaurus. To run applications on

the Zaurus (and the qvfb) you need to link against QPE rather then Qt. See section 4 for more details about qvfb.

To start development you need to obtain the Qtopia SDK from Trolltech. GPL edition

(qtopia-free-1.5.0-1.i386.rpm) can be located at the following URL. Note that if you use this GPL version, you

have to follow the terms and conditions set forth in the GPL (GNU Public License, see http://www.gnu.org/

for

details). If you are doing commercial development you need to obtain the commercial SDK:

http://www.trolltech.com/developer/download/qtopia.html

. (GPL edition Qtopia SDK)

https://www.regnow.com/softsell/nph-softsell.cgi?item=7131-1

(Commercial Edition)

Install the rpm in the same manner as to how the cross compiler was installed:

rpm -Uvh qtopia-free-1.5.0-1.i386.rpm

By default, RPM installs the Qtopia SDK in the

/opt/Qtopia/

directory.

1.1.4. Configuring Your Compiler Environment

After the toolchain and the SDK are installed, you should create the two batch files in your home directory. One

sets up the environment variables for compiling x86 versions of SL-series Zaurus applications (using the qvfb)

and the other for setting the environment variables for doing native ARM cross-compiling for the SL-series Zaurus.

More information can be found at (http://docs.zaurus.com/linux_compiler_setup_howto.shtml

) The following are

examples of the scripts:

Batch file #1, dev-x86-qpe.sh

#!/bin/bash

# dev-x86-qpe.sh

# location : /usr/bin

if [ -z ${ORG_PATH} ]

then

ORG_PATH=${PATH}

export ORG_PATH

if [ -z ${ORG_LD_LIBRARY_PATH} ]

then

ORG_LD_LIBRARY_PATH=${LD_LIBRARY_PATH}

export ORG_LD_LIBRARY_PATH
