Installing Qt for Symbian SDK 4.6.2 on Linux

Qt 4.6.2 was released last Monday, so I took some time to update the GnuPoc and Qt installer scripts I previously released for 4.6.1.

Besides the upgrade to Qt 4.6.2, there are other minor changes:

• Both installers now check MD5 signatures of the necessary files, to make sure they are not corrupted.
• The GnuPoc installer now supports the 3.1 SDK (see updated instructions below).
• Added “unset QMAKESPEC” command to setup instructions (at least Gentoo sets it globally, which affects qmake).

The instructions are basically the same as the previous ones, but I will post the full instructions here for completeness.

Preparation

Download all required files to a single directory (e.g. “~/downloads”):

• S60_5th_Edition_SDK_v1_0_en.zip (623MB) or S60-SDK-200634-3.1-Cpp-f.1090b.zip (355MB): S60 SDK for Symbian OS (be sure to click on the “Download all-in-one S60 SDKs” button for 5th edition, or “Download S60 SDKs for C++” for 3rd edition, FP1)
• s60_open_c_cpp_plug_in_v1_6_en.zip (35MB): Open C/C++ Plug-in
• qt-symbian-opensource-4.6.2.exe (201MB): Qt for Open Source C++ development on Symbian
• gnu-csl-arm-2005Q1C-arm-none-symbianelf-i686-pc-linux-gnu.tar.bz2 (11MB): CodeSourcery’s ARM toolchain for Symbian
• gnupoc-package-1.15.tar.gz (6.2MB): tools and patches to run Symbian SDK on Linux
• gnupoc_1.15_installer_v2.sh: Unofficial GnuPoc installer (supports 3.1 and 5.0 SDKs)
• qt_for_symbian_4.6.2_linux_installer_v3.sh: Unofficial Qt for Symbian installer for Linux

For building the native tools from gnupoc, you will need:

• the GCC C/C++ compilers
• development files for zlib
• development files for openssl

On Ubuntu, you can install these using the following command:

sudo apt-get install build-essential zlib1g-dev libssl-dev

Installation

First, install GnuPoc + S60 SDK + the Open C/C++ plugin:

./gnupoc_1.15_installer_v2.sh \
    <download-dir> \
    <gnupoc-dir>\
    <x.y>

Replace <download-dir> with the location of all files downloaded in previous section (e.g. “~/downloads”), <gnupoc-dir> with the destination directory for GnuPoc and the SDK files (e.g. “~/gnupoc”) and <x.y> with the SDK version you want to install (e.g. “3.1″ or “5.0″). Note that both directories must have absolute paths.

If installation was successful, you should see an output like:

Installation has finished. Before using the GnuPoc SDK, run these commands on the console:
 
export PATH=<gnupoc-dir>/bin:$PATH
export EPOCROOT=<gnupoc-dir>/symbian-sdks/5.0/ # trailing "/" is required!
 
(These commands must be run again every time a new console is opened.)

Run the commands as instructed on the message. Next, install Qt for Symbian:

./qt_for_symbian_4.6.2_linux_installer_v3.sh \
    <download-dir> \
    <qt-s60-dir>

Replace <download-dir> with the location of all files downloaded in previous section (e.g. “~/downloads”), and <qt-s60-dir> with the destination directory for the Qt files (e.g. “~/gnupoc/qt-4.6.2″). Note that both directories must have absolute paths.

If installation was successful, you should see an output like:
Installation has finished. Before using the Qt for Symbian SDK, run this command on the console:
 
export PATH=<qt-s60-dir>/bin:$PATH
unset QMAKESPEC    # make sure there is no QMAKESPEC variable set
 
(This command must be run again every time a new console is opened.)

Before using Qt for Symbian, you should run the command as instructed on the message above.

Usage example

To test the installation, I will describe how to build the “colliding mice” example.

1. cd into the example source:

cd <qt-s60-dir>/examples/graphicsview/collidingmice/

2. Now build the example and generate the SIS file

qmake
make debug-gcce
make sis

A few notes:

• Make sure Qt is installed on the device before installing Qt applications. The easiest way to install it is to copy the “qt_installer.sis” package found under <qt-s60-dir> over bluetooth and open the received message to begin the installation.
• Only the “debug-gcce” (if you are using the GCCE toolchain AKA “CodeSourcery toolchain”) or “debug-armv5″ (if you are using RVCT) will work, because the current Qt releases only ship debug versions of the libraries
