wmfscpos is a wmaker dockapp which displays the temperature, voltage and fan information from an FSC Poseidon chip.
wmfscpos was formerly known as wmlm-fsc and is based on Ben Jarvis' wmlm.
If you're using kernel 2.4, you'll need the additional modules from lm_sensors.
2.6 series kernels starting from 2.6.12 include the new fscpos driver. For kernels 2.6.10 and 2.6.11 you can get a patch from the downloads section.
Building wmfscpos is rather easy:
# cd wmfscpos-1.0.0-RC1/wmfscpos/
# make install
Debian GNU/Linux users might fetch a binary from this project's website or just
build their own. You need to have debhelper, xlibs-dev and libsensors-dev
installed for that:
# cd wmfscpos/
# fakeroot debian/rules binary
