[collectd] collectd-3.7.1 compile error, et. al.

Same applies for me. As the ACPI code is based on information provided by me,
I will try to trace down the problem during the next days. I didn't test this
plugin until now ;-)

strace did show me that /proc/acpi/battery/BAT1/state (which is the right file
in my case) was read by collectd - however not much happened after that...

AFAIK, you're right... this plugin does not support APM. It should handle all
batteries found on the system.

Did you use the 3.7.1 tarball or did you use a Subversion checkout?

To check if the battery module is present, you can simply look for
/usr/lib/collectd/battery.so ;-)

Those are lines 44 thru 48 of network.c:

44  #ifdef HAVE_LIBRRD
45  extern int operating_mode;
46  #else
47  static int operating_mode = MODE_CLIENT;
48  #endif

As the error occurs on line 47, this means you don't have librrd*-dev
installed. How could you build the package without it? librrd*-dev is a build
dependency.

Anyway, this looks like a bug to me ;-) However, I don't know exactly which
changes are implied by not having HAVE_LIBRRD defined.

Well, the second part of the name ("w83697hf" in this case) is an identifier 
of the chip. You have to adjust it to the name of your chip...

None that I know of.
