Installing this patch on QNX SDP 6.4.1

To install this patch on QNX SDP 6.4.1, do the following:

1. Log in as root (or with administrator privileges on Windows).
2. On Debian 3.1 hosts, set up your environment by typing:

   source /etc/profile
     

3. Download the patch-640-1523-applypatch.tar archive to your host environment.
4. On Windows hosts, run cmd.exe.
5. Use the applypatch utility to install the patch:
   • On Linux, if you use sudo (as would be the case on Ubuntu), you must specify the -E option to preserve the environment. In this case, the PATH environment variable is set to a safe one for security reasons, so you need to specify the full path to the utility:

     sudo -E $QNX_HOST/usr/bin/applypatch patch-640-1523-applypatch.tar
         

   • On other hosts, type:

     applypatch patch-640-1523-applypatch.tar
         

   For more information about applypatch, see its entry in the Utilities Reference.

Installing this patch on QNX SDP 6.4.0

1. Log in as root (or with administrator privileges on Windows).
2. On Debian 3.1 hosts, set up your environment by typing:

   source /etc/profile
     

3. Download the patch-640-1523-applypatch.tar archive to your host environment.
4. Determine the base directory of your QNX SDP installation by opening a command shell and using the qconfig command. For example:

   $ qconfig
   QNX Installations
   
     Installation Name: QNX Software Development Platform 6.4.0
               Version: 6.4.0
        Base Directory: /usr/qnx640/
              QNX_HOST: /usr/qnx640/host/qnx6/x86/
            QNX_TARGET: /usr/qnx640/target/qnx6/
     

   The base directory in this example is /usr/qnx640/, but it could be different on your machine, depending on your host and where you installed QNX SDP.

5. Extract the archive you downloaded into the base directory:
   • Windows hosts:
     1. Open a command prompt (cmd.exe) and switch to the drive indicated in the base directory that you found earlier (e.g. C:).
     2. Copy the archive to your base directory, replacing base_dir with the path you found earlier:

        copy drive:\patch-640-1523-applypatch.tar base_dir

     3. Use the following commands to extract the archive contents. Don't specify the drive letter in the archive path:

        cd base_dir
        tar -xvf patch-640-1523-applypatch.tar

   • Neutrino, Linux, and Solaris hosts:

     Open a command shell and use the following commands (replacing base_dir with the path found earlier, and archive_path with the full path to the downloaded archive):

     cd base_dir
     tar -x -v -f archive_path/patch-640-1523-applypatch.tar

Structure of a patch

The patch is installed in the base_dir/patches/640-1523/ directory. This directory includes:

version

Includes the patch number and the build information.

manifest

Contains the checksums of the files shipped in the patch (as generated by the cksum utility).

shiplist

A list of the files included in the patch.

host

A directory of fixes related to components that would be built into host-specific development systems.

---

The patch might include components for hosts other than the one you're using. Before applying the patch, you can remove any unnecessary directories under base_dir/patches/640-1523/host.

---

Applying the patch

Next, you must replace the files on your development host with the patched files.

---

Since this is a destructive procedure, we recommend that you create a backup of the affected files.

---

Creating a backup

To create a backup on any of our hosts:

1. (Windows only) From the cmd.exe prompt, run ksh.
2. Go to the base directory:

   cd base_dir

3. Make a backup of the files that will be overwritten:

   pax -w < patches/640-1523/shiplist > patches/640-1523-backup.tar

   You can use whatever name you like for the backup archive. The pax utility might display some error messages when it attempts to back up nonexistent files for host operating systems other than the one you're using. You can ignore these messages.

4. (Windows only) Exit ksh.

Copying the files — Windows hosts

To apply the patch on a Windows system from the command prompt (remember to switch back to cmd.exe from ksh):

1. Switch to the drive specified in your base directory (e.g. C:).
2. Go to the patch directory (remember to replace / characters in the base directory with \):

   cd base_dir\patches\640-1523

3. Install the host updates:

   cp -Rp host base_dir\.

Copying the files — Neutrino and Linux hosts

To apply the patch on a Neutrino or Linux system:

1. Go to the patch directory:

   cd base_dir/patches/640-1523

2. Install the host updates:

   cp -Rp host base_dir/.

Uninstalling this patch on QNX SDP 6.4.1

To uninstall this patch on QNX SDP 6.4.1, do the following:

1. Log in as root (or with administrator privileges on Windows).
2. On Debian 3.1 hosts, set up your environment by typing:

   source /etc/profile
     

3. On Windows hosts, run cmd.exe.
4. Use the applypatch utility to install the patch:
   • On Linux, if you use sudo (as would be the case on Ubuntu), you must specify the -E option to preserve the environment. In this case, the PATH environment variable is set to a safe one for security reasons, so you need to specify the full path to the utility:

     sudo -E $QNX_HOST/usr/bin/applypatch -U 1523
         

   • On other hosts, type:

     applypatch -U 1523
