I have lm_sensors installed and working, I can type "sensors" from the console and I will get a nice list of the CPU temperatures as I want them.

However I would also like to have the xfce4-sensors-plugin working so that I can have a more convenient manner of observing the temperature.

I get the following errors upon compilation:

../lib/.libs/libxfce4sensors.so: undefined reference to `sensors_get_feature'
../lib/.libs/libxfce4sensors.so: undefined reference to `sensors_get_all_features'
../lib/.libs/libxfce4sensors.so: undefined reference to `sensors_get_ignored'
collect2: ld returned 1 exit status
make[2]: *** [xfce4-sensors-plugin] Error 1

make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/tmp/SBo/xfce4-sensors-plugin-'
make: *** [all] Error 2
This is the output from the Slackware package from slackbuilds.org for version 0.1.

I have also tried version 0.9 and 1.0 (compile directly from source, no package) -- to no avail.

I tried looking at the source to identify where these functions missing are, I couldn't find them in the source, which makes me believe this is a library that I'm missing. However, which library? When I search on e.g. Freshmeat.net I only find one applicable entry for "sensors", and on Slackbuilds.org I only find the 0.1 version of this plugin -- not even anything lm_sensors related at all besides that one.

My system is a plain x86 with Slackware 13.1.

Any thoughts?
