About This Guide

Thank you for choosing the QNX Software Development Platform version 6.5.0. This guide tells you how to install it from DVD or CD.

Please read this preface for information that applies to all host OSs:

Typographical conventions

Throughout this manual, we use certain typographical conventions to distinguish technical terms. In general, the conventions we use conform to those found in IEEE POSIX publications. The following table summarizes our conventions:

Reference	Example
Commands	`make`
Environment variables	PATH
File and pathnames	`/dev/null`
Keyboard keys	Enter
Variable names	stdin
User-interface components	Cancel

We use an arrow (→) in directions for accessing menu items, like this:

You'll find the Other... menu item under Perspective-->Show View.

We use notes and cautions to highlight important messages:

Notes point out something important or useful.

Cautions tell you about commands or procedures that may have unwanted or undesirable side effects.

Before you start

Before you install this software, please note the following:

QNX SDP 6.5.0 introduces a new licensing scheme; for more information, see “What's new: Licensing” in the release notes.

The 6.5.0 installers do a fresh installation of the QNX Software Development Platform.
On Linux and Windows hosts, QNX SDP 6.5.0 includes the QNX Momentics Tool Suite, which you can use to develop applications to run on the QNX Neutrino RTOS on a separate target system.
QNX SDP 6.5.0 for self-hosted QNX Neutrino systems first installs the QNX Neutrino RTOS, followed by the QNX Momentics Tool Suite.
QNX SDP 6.5.0 includes everything you need to build for all supported target platforms (ARM, MIPS, PowerPC, SH-4, and x86).
The DVD includes QNX SDP for all host OSs for creating software for all supported targets; the CD includes QNX SDP for QNX Neutrino hosts that you can use to build software for x86 targets only.
If you downloaded a CD or DVD image from our website, make sure that its checksum matches that given on the website.
Once you've installed the QNX Software Development Platform, you can find the license agreements in base_dir/install/qnxsdp/6.5.0, where base_dir is where you installed SDP (see the output from the qconfig command).
QNX SDP 6.5.0 can coexist with QNX SDP 6.4.0, 6.4.1, and QNX Momentics 6.3, but if you want 6.5.0 to replace 6.4.1, 6.4.0, or 6.3, you must uninstall the older versions and any updates to them before installing 6.5.0. You should uninstall QNX products in the reverse order in which you installed them. To determine this order, use a command like this:
QNX Neutrino hosts
```
ls -lt `find base_directory -name "*uninstall*.sh"`
  
```
Windows hosts
```
ls -lt `$QNX_HOST/usr/bin/find base_directory -name "*uninstall*.exe"`
  
```
Linux hosts
```
ls -lt `find base_directory -name "*uninstall*.bin"`
  
```
where base_directory is where you installed the QNX Software Development Platform.

Getting started with the documentation

After you've installed QNX SDP 6.5.0, you'll find an extensive set of HTML documentation:

On Linux and Windows development hosts, you can read it in the Integrated Development Environment's help system. On Linux, use the qde command to start the IDE; on Windows, use the desktop icon.
On self-hosted QNX Neutrino systems, you can read it in the Photon helpviewer, or you can use a web browser to display:
${QNX_TARGET}/usr/help/product/momentics/bookset.html

The “roadmap” page contains links to the various HTML booksets that accompany the OS. We recommend that you start with Welcome to the QNX Software Development Platform for an overview of QNX SDP. Next, see 10 Steps to Developing a QNX Program: Quickstart Guide for a short tutorial that will help you get started, and then refer to the other documents (System Architecture, QNX Neutrino Programmer's Guide, Library Reference, Utilities Reference, and so on).

For information about new features and known issues in QNX SDP, see the release notes. The online documentation includes a copy, but for for the most up-to-date version, go to our website, www.qnx.com, log into your myQNX account, and then go to the Download area.

You can install and work with multiple versions of QNX Neutrino. Whether you're using the command line or the IDE, you can choose which version of the OS to build programs for. For more information, see the IDE User's Guide or the QNX Neutrino Programmer's Guide.
