With regards to the rest, I don't understand where to put LD_LIBRARY_PATH
and also the weewxd
first try these two lines at the command prompt:
export LD_LIBRARY_PATH=/opt/owfs/lib
weewxd /etc/weewx/weewx.conf
the LD_LIBRARY_PATH tells weewxd where to find shared libraries. most of the
time you don't have to set LD_LIBRARY_PATH, because libraries live in locations
that are already known, e.g., /lib or /usr/lib. /opt/owfs is a standard way to
install owfs, but /opt/owfs/lib is not in the list of known library locations.
Weewx is being run as a service. ie sudo service weewx start
There is no RC script as far as I am aware.
/etc/init.d/weewx is the RC script. it is invoked when you do 'sudo service
weewx start'
if setting the LD_LIBRARY_PATH worked in the experiment above, then you need to
set it when weewxd is run via the rc script.
one way to do that is to put this near the top of the rc script:
LD_LIBRARY_PATH=/opt/owfs
a safer way to do that is to put it in the defaults file for weewx:
echo "LD_LIBRARY_PATH=/opt/owfs" | sudo tee /etc/defaults/weewx
that way you won't have to modify /etc/init.d/weewx every time up upgrade weewx.
