Installation procedure

Log in as root (or with administrator privileges on Windows).
Open a web browser, go to our website, www.qnx.com, and log on to your myQNX account.
Click Download Center-->Products & Updates-->QNX Momentics-->QNX Momentics 6.3.x-->QNX Momentics 6.3.0 Service Pack 2 and related downloads-->QNX Momentics 6.3.0 Service Pack 2 Patches and Updates.
Download the patch-630SP2-0487-qconn-401.tar archive to your host environment.
Determine the base directory of your QNX Momentics installation by opening a command shell and using the qconfig command. For example:
```
$ qconfig
QNX Installations

Installation Name: QNX Momentics 6.3.0
Version: 6.3.0
Base Directory: /usr/qnx630/
QNX_HOST: /usr/qnx630/host/qnx6/x86/
QNX_TARGET: /usr/qnx630/target/qnx6/
  
```
The base directory in this example is /usr/qnx630/, but it could be different on your machine, depending on your host and where you installed QNX Momentics.

Extract the archive you downloaded into the base directory:

Method 1: Command-line based

Windows hosts:
1. Open a command prompt (cmd.exe) and switch to the drive indicated in the base directory from step 2 (e.g. C:).
2. Copy the archive to your base directory, replacing base_dir with the path from step 2:
  copy drive:\patch-630SP2-0487-qconn-401.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-630SP2-0487-qconn-401.tar
Neutrino, Linux, and Solaris hosts:
Open a command shell and use the following commands (replacing base_dir with the path from step 2, and archive_path with the full path to the downloaded archive):
cd base_dir
tar -x -v -f archive_path/patch-630SP2-0487-qconn-401.tar

Method 2: GUI based

Use any GUI-based application that supports the TAR format (e.g. WinZIP under Windows). Ensure that the destination directory is your base directory.

If you use WinZIP, choose Options-->Configuration, switch to the Miscellaneous tab in this dialog, and turn off the TAR file smart CR/LF conversion option. If this option is turned on, and you extract the archive, then your shiplist file will contain ^M characters.

Structure of a patch

The patch is installed in the base_dir/patches/630SP2-0487/ 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.
target: A directory of fixes related to components that would be built into QNX Neutrino target or runtime systems.

Applying the patch

Next, you must determine how to incorporate the patch into your host system. The patch is stored in a directory (or folder) that's separate from your development system. This allows you some flexibility in how to apply the patch.

There are three methods for using a patch:

modifying build and configuration files to look in the patch subdirectory
creating an override directory tree
replacing the development host files with those from the patch.

Method 1: Modifying build and configuration files

In the first method, you can use the files in the patch by simply modifying buildfiles to include the full path to the files in the patch subdirectory. This allows you to test the patch before committing to it. It doesn't affect your development host. If you choose to stop using the patch, you just need to change the buildfiles back.

Method 2: Using an override directory tree

You can use a similar approach that involves creating an "override" tree. You can tell the system builder and mkifs utilities to look for binaries in a particular subdirectory before looking in the standard location ($QNX_TARGET).

To do this from the command line:

cd base_dir
mkdir build
pax -rw patches/630SP2-0487/target/qnx6/* build/
Add base_dir/build to your system builder paths. For mkifs, you can use the -r option, specifying the same path.

Method 3: Replacing the development host files

The third method replaces 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:

(Windows only) From the cmd.exe prompt, run ksh.
Go to the base directory:
cd base_dir
Make a backup of the files that will be overwritten:
pax -w < patches/630SP2-0487/shiplist > patches/630SP2-0487-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.
(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):

Switch to the drive specified in your base directory (e.g. C:).
Go to the patch directory (remember to replace / characters in the base directory with \):
cd base_dir\patches\630SP2-0487
Install the target updates:
cp -Rp target base_dir\.

Copying the files -- Neutrino, Linux, and Solaris hosts

To apply the patch on a Neutrino, Linux, or Solaris system:

Go to the patch directory:
cd base_dir/patches/630SP2-0487
Install the target updates:
cp -Rp target base_dir/.
(QNX Neutrino only) If the patch includes a target/qnx/x86 directory, install the runtime updates:
```
cd target/qnx6/x86
cp -fRp . /
  
```

Updating your target system

After installing this patch, you need to update the version of qconn on your target machine. How you do this depends on your target system; you might have to build a new image, or you might simply have to copy the new version to your target. For example:

Use slay qconn on the target to stop any existing qconn.
Copy $QNX_TARGET/target/usr/sbin/qconn to your target system's /usr/sbin directory.
Make sure the qconn in the target's /usr/sbin directory is executable; if it isn't, use chmod +x to make it executable.
On the target, launch the new qconn.
