System requirements

---

We're deprecating support for Linux Red Hat 8 and 9; QNX Momentics 6.3 is the last release that you can install on these hosts.

---

In order to install the QNX Neutrino Core OS 6.3.2A, you need approximately 60 MB of disk space, including the space required for backups and temporary space used in installing the files. About half of this disk space must be where your temporary directory resides.

The QNX Neutrino Core OS 6.3.2A installer doesn't support JRE 1.5. The installer needs the Sun JVM; it doesn't work with the IBM JVM.

The System Profiler in the SP2 and SP3 version of the IDE requires a minimum color depth of 16 bits.

Related products

After you've installed the QNX Neutrino Core OS 6.3.2A, you might want to install these related products:

---

The SP2 to SP3 Update and SP3 contain the latest documentation, including the Documentation Update 1.0.0. Don't install the Documentation Update 1.0.0 after installing the SP2 to SP3 Update or SP3, or your system's documentation will be in an inconsistent state.

---

Any other products that we've released for SP1, SP2, or SP3 are compatible with the QNX Neutrino Core OS 6.3.2A.

The following patch addresses issues that we discovered since releasing QNX Momentics 6.3.0 Service Pack 2:

Debug Malloc Library Patch (Patch ID 155)

A version of the debug malloc library that works correctly on SH platforms. (Ref# 27639)

You can install it before or after installing the QNX Neutrino Core OS 6.3.2A. This patch is included in QNX Momentics 6.3.0 Service Pack 3. For the latest patches, see our website.

There are several ways that you incorporate QNX Momentics 6.3.0 Service Pack 3 in your system, depending on what you've already installed:

Here's a summary:

• To do a fresh installation, use QNX Momentics 6.3.0 Service Pack 3.
• If you've already installed 6.3.0 SP2, install the 6.3.0 SP2 to SP3 Upgrade.
• You can install the QNX Neutrino Core OS 6.3.2A on a system that has SP3, or SP2 plus the 6.3.0 SP2 to SP3 Upgrade.
• If you've installed the QNX Neutrino Core OS 6.3.2 or the QNX Neutrino Core OS 6.3.2A on a system that has 6.3.0 SP2, and you want to upgrade to SP3, install the 6.3.0 SP2 to SP3 Upgrade.

  Installing the 6.3.0 SP2 to SP3 Upgrade on a system with the QNX Neutrino Core OS 6.3.2 updates the core OS to 6.3.2A.

Installing the QNX Neutrino Core OS 6.3.2A

The installer backs up the affected files, and it stores the backup in base_directory/install/ntocore/6.3.2/backup.jar (see “Determining your base directory,” below).

If you interrupt the backup, or it fails, the installation is aborted. Before you can try again to install the QNX Neutrino Core OS 6.3.2A, you must delete the base_directory/install/ntocore/6.3.2 directory

The QNX Neutrino Core OS 6.3.2A doesn't change any user files. For a list of the affected files, see base_directory/install/ntocore/6.3.2/shiplist after installing the archive.

---

If you've installed QNX Momentics 6.3.0 SP1 on your machine, but not SP2, and you later decide to install SP2, you must uninstall the QNX Neutrino Core OS 6.3.2A and its related products first. Close all QNX Momentics applications before you install the QNX Neutrino Core OS 6.3.2A. If you haven't set your HOME environment variable, the installer sets it to be the directory where you installed QNX Momentics (e.g. /opt/qnx630).

---

To install the QNX Neutrino Core OS 6.3.2A, do the following:

1. Log in as root.
2. Log into your myQNX account on our website, and then go to the Download Center.
3. Download the QNX Neutrino Core OS 6.3.2A package, ntocore-6.3.2a-nnnnnnnnnnn-linux.bin, where nnnnnnnnnnn is an 11-digit build number. The package is a .bin script.
4. Run chmod to make the script executable. For example:

   chmod a+x ntocore-6.3.2a-20061234567-linux.bin

5. Run the script at the system prompt. For example:

   ./ntocore-6.3.2a-20061234567-linux.bin

   ---

   If InstallShield complains that it can't find a JVM, make sure that you've successfully installed QNX Momentics 6.3.0 before you try to install the QNX Neutrino Core OS 6.3.2A.

   ---

6. Follow the instructions provided by InstallShield.
7. If InstallShield doesn't display the release notes, launch a browser and use it to display base_directory/install/ntocore/6.3.2/rel_6.3.2a_core_os.html (see “Determining your base directory,” below).
8. If you're installing on a Red Hat Enterprise version 4 host, log out and back in again.

The installer automatically installs the qconfig Patch (Patch ID 205), which installs a new version of qconfig that provides more information about the QNX products that you've installed. The Documentation Update 1.0.0 includes updated information about this utility. (Ref# 29317)

Uninstalling the QNX Neutrino Core OS 6.3.2A

---

If you delete or rename the backup that was made when you installed the QNX Neutrino Core OS 6.3.2A, or if the backup has been corrupted, the uninstaller will warn you. Continuing to uninstall the QNX Neutrino Core OS 6.3.2A will leave your system with an incomplete version of QNX Momentics 6.3.0, and you won't be able to reinstall the QNX Neutrino Core OS 6.3.2A; you'll likely have to completely reinstall QNX Momentics 6.3.0. Use our uninstaller to remove the QNX Neutrino Core OS 6.3.2A; if you simply delete the directories, your machine might end up in an inconsistent state, and you might not be able to run the IDE. You should uninstall QNX products in the reverse order in which you installed them. To determine this order, use a command like this: ls -lt `find base_directory -name "*uninstall*.bin"` where base_directory is where you installed QNX Momentics.

---

To uninstall the QNX Neutrino Core OS 6.3.2A, do the following:

1. Log in as root.
2. Go to the base_directory/_uninstall/ntocore/6.3.2 directory (see “Determining your base directory,” below).
3. Start the QNX InstallShield application:

   ./uninstaller.bin
     

   InstallShield will now remove the QNX Neutrino Core OS 6.3.2A.

How can I tell if I've already installed the QNX Neutrino Core OS 6.3.2A?

To determine whether or not you've installed the QNX Neutrino Core OS 6.3.2A, use the qconfig command or check for the existence of the base_directory/install/ntocore/6.3.2 directory (see “Determining your base directory,” below).

Determining your base directory

To determine the base directory for QNX Momentics, open a command shell and use the qconfig command. For example:

$ qconfig
QNX Installations

  Installation Name: QNX Momentics 6.3.0
            Version: 6.3.0
     Base Directory: /opt/qnx630/
           QNX_HOST: /opt/qnx630/host/linux/x86/
         QNX_TARGET: /opt/qnx630/target/qnx6/

The base directory in this example is /opt/qnx630/, but it could be different on your machine, depending on where you installed QNX Momentics.

Getting started with the documentation

After you've installed your development suite, you'll find an extensive set of online documentation in HTML format. Look under the following directory:

${QNX_TARGET}/usr/help/product/momentics/bookset.html

This “roadmap” page contains links to the various HTML booksets that accompany the OS (e.g. System Architecture, Programmer's Guide, Library Reference, Utilities Reference, etc.).

You'll find the installation and release notes in the base_directory/install/ntocore/6.3.2 directory (see “Determining your base directory,” above).

---

For the most up-to-date version of the installation and release notes, go to our website, www.qnx.com, log into your myQNX account, and then go to the Download Center.

---

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.

---

Coexistence of 6.3 and 6.2.1 is supported only on Windows and Solaris hosts (we didn't support Linux hosts in 6.2.1).
