If you aren't going to use owtcl, try
./configure --disable-owtcl
I'm perplexed by the owserver in background problem. Is it being loaded from the command line, or within the nagios system. Perhaps Nagios doesn't allow owserver to fork into the background?

Hi,
I've been trying to integrate owfs with my Nagios (www.nagios.org)
installation at work this week and have had a few problems.
The system is Debian Sarge, kernel 2.6.8.
I run ./configure in the owfs-2.5p5 folder, this seems to complete ok.
Ends with :
Current configuration:
Deployment location: /opt/owfs
Compile-time options:
Caching is enabled
USB is DISABLED
I2C is enabled
HA7Net is enabled
Multithreading is enabled
Parallel port DS1410E is enabled
TAI8570 barometer is enabled
Thermocouple is enabled
Debug-output is enabled
Profiling is DISABLED
Zeroconf (Bonjour) is DISABLED
Module configuration:
owfs is enabled
owhttpd is enabled
owftpd is enabled
owserver is enabled
owcapi is enabled
swig is enabled
owperl is enabled
owphp is DISABLED
owpython is enabled
owtcl is DISABLED
Then I run `make`, which appears to chug along happily for a while and then
borks with the following :

After all that, I was able to run owserver and connect to a Link Hub.
If I run owserver with --forground, it's fine, I can access readings with
owread (which is great btw).
Running in background though, any attempt to owread results in owserver
unloading.
Not knowing how to fix all this, but still keen to make some progress, I had
a look at the python bindings.
I hacked together this script.
#! /usr/bin/env python
import ow
import sys
def main(argv=None):
if argv is None:
argv = sys.argv
if len( argv ) < 2:
print "usage: temperature.py serial_port_path ID temperature|humidity
CriticalLow WarningLow WarningHigh CriticalHigh"
return 3
else:
ow.init(argv[1])
sensor=ow.Sensor (argv[2])
if argv[3]=="temperature":
v=float(sensor.temperature)
elif argv[3]=="humidity":
v=float(sensor.humidity)
if v>float(argv[7]) or v<float(argv[4]):
print "CRITICAL: ", v
return 2
elif v>float(argv[6]) or v<float(argv[5]):
print "WARNING: ", v
return 1
else :
print "OK:", v
return 0
if __name__ == "__main__":
sys.exit(main())
This runs and works fine if I run it manually, but when nagios runs it
fails.
I narrowed it down to this line :
sensor=ow.Sensor(argv[2])
if I comment this out and fake the data it all works, nagios accepts the
results of the script.
With it in something fails.
Thanks for reading, sorry it's so long.
