Installation procedure
To install the process manager Proc32:
- Log in as root
- Download the archive (QNX4-Proc32-425Q_20050719.tar.gz).
- Get the cksum to ensure that the archive is correct:
# cksum QNX4-Proc32-425Q_20050719.tar.gz
- Compare the result against the checksum posted on our website http://www.qnx.com/download
- Extract the archive with the updated drivers:
# cd /
The following procedure will overwrite your existing /boot/sys/Proc32. Make sure to save it into a backup directory if you wish to keep it.
# gzip -d <download-path>/QNX4-Proc32-425Q_20050719.tar.gz # tar -xvof <download-path>/QNX4-Proc32-425Q_20050719.tar
The following files will be installed:
- /boot/sys/Proc32
- /boot/sys/Proc32-cksum.txt
- Make sure that the Proc32 binary is executable:
# chmod 775 /boot/sys/Proc32 # chown root:root /boot/sys/Proc32
 |
Please make sure to build the OS image as documented in the QNX 4 manual in
order to take advantage of this new Proc32.
For instance:
# cd /boot
# buildqnx -v ./build/myimage ./images/myimage
Backup the existing OS image into the alternate boot, in case you ever need it:
# cp -V /.boot /.altboot
Copy the new OS image into /.boot:
# cp -V ./images/myimage /.boot
Then reboot your system. |
