Installation

• Log into dev-vm101 as user kvalobs
• If an old kvqc2 exists stop the running kvqc2 process by 'kvstop -l' (lower case L), then type the number corresponding to kvqc2
• Remove active configuration files (this is to just ensure that when the new kvqc2 version is set running it does not find and use an old configuration file)

For example:

$ cd /etc/kvalobs/Qc2Config
$ mv XXX.cfg XXX.hold 
$ mv ProcessUnit.cfg ProcessUnit.hold

( PS NOTE: actually now all the earliy config files have been moved to /etc/kvalobs/Qc2Config/old )

• Install the latest version of kvqc2
• Log in as a user with sudoer permission
• NB one may need to run “apt-get update” first in order to update the package list.

$ sudo apt-get install kvqc2

An alternative is to install the new kvqc2 directly from where the debian package was built on dev-vm101:

i.e. using “sudo dpkg -i kvqc2_1.0.1-1_i386.deb” as illustrated below.

paule@dev-vm101:~/kvqc2-1.0.1$ ls
kvqc2-1.0.1            kvqc2_1.0.1-1_i386.changes  kvqc2_1.0.1.orig.tar.gz
kvqc2_1.0.1-1.diff.gz  kvqc2_1.0.1-1_i386.deb      kvqc2-1.0.1.tar.gz

paule@dev-vm101:~/kvqc2-1.0.1$ sudo dpkg -i kvqc2_1.0.1-1_i386.deb

Bug Fix and Confirmation of apt-get install

Initial tests illustrated that some data was written back to thedatabase at too high a precision. This is fixed in revision 1782: https://svn.met.no/viewvc/kvoss?view=rev&revision=1782 and led to a kvqc2-1.0.2 revision. This also provided the opportunity to check that the install from apt-get install works, i.e.:

paule@dev-vm101:~$ sudo apt-get install kvqc2

Even then, there are surprises in store when building kvQc2:

• requires netcdf
• requires the GNU Scientific Library
• utilises a number of other boost libraries (ITEMIZE) TBD

…. more will appear here in time …
