Re: [weewx-user] Re: Weewx not working after update

2016-11-27 Thread David Johns 

Thanks M..

That has sorted Weewx from crashing. I also did have the unrecoverable error 
below but I have corrected that by comparing my config with weewx.conf.dist. I 
found I had some old template tags from when I was messing with different 
templates months ago. No idea why they would have caused problems now but I am 
glad I resolved this one.

I also messed up my templates as they had been overwritten in the upgrade but I 
have now corrected these.

I realise I have a problem with my AAG wind instrument and I think I will take 
it down tomorrow and give it a service in an attempt to resolve this.

The remaining problem I have now is that I cannot get either my new HB 
barometer or the EDS0066 pressure sensor to work.

david,

i mistyped.  the directory is /etc/default, not /etc/defaults.  so do this:

echo "LD_LIBRARY_PATH=/opt/owfs/lib" | sudo tee /etc/default/weewx

that should make weewx run properly when you invoke it using the 'service' 
command.

your second problem is actually a bigger issue - owfs is not returning data for 
your sensors.  is the owfs server running? (it looks like you are reading from 
the owfs server, not from a serial/i2c/usb interface)

now you have a problem reading a sensor.

please install owfs 0.19rc1.  it will provide more details about the sensor 
problem.

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

/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.

2016-11-27 Thread David Johns 

Hi

owfs was installed in /opt/owfs as I believe that is the default when it was 
installed by compiling.

With regards to the rest, I don't understand where to put LD_LIBRARY_PATH and 
also the weewxd

Weewx is being run as a service. ie sudo service weewx start

There is no RC script as far as I am aware.

My owfs is actually located in opt/owfs as it is compiled to the latest 
version. The latest on offer through Ubuntu is only 2.9 and I believe this does 
not support the new Hobbyboards barometer.


david,

where was owfs in your previous installation/configuration? did you 
build/install it yourself, or did you install it using your system's package 
manager?

you probably just need to set LD_LIBRARY_PATH so that weewx can find the shared 
libraries.  for example, try something like this:

export LD_LIBRARY_PATH=/opt/owfs/lib
weewxd /etc/weewx/weewx.conf

if that works, then set LD_LIBRARY_PATH in your rc script

simulator works because it does not use owfs
