HowTo's VSCP

#VSCP update process #howto

In previous versions of VSCP whenever you did an install all configuration files were replaced with the latest version. This is not true anymore.  Now the new version is instead written as a copy with the date of the install appended to it.  So if you after a “make install” or a “dpkg -i vscpd” want the latest configs you have to copy the backup to the actual config file and restart the VSCP server.

Files that is handled in this way is

/etc/vscp/vscpd.conf
/srv/vscp/dm.xml
/srv/vscp/simtempdata.txt
/srv/vscp/variables.xml

Also if you are on unstable code you should remove the databases before you start the updated server . Use

rm /srv/vscp/*.sqlite3

for this.

Also note that the web sample code is not installed in the install/update process no more. The process to get this subsystem installed with be described later.
