An i386 binary is provided, built under Fedora Core 3. Various file paths are hardcoded i.e
/proc/acpi/ac_adapter/ADP0/state /proc/acpi/battery/BAT0/info /usr/share/enlightenment/epplet_data/E-Power/E-Power-Bat-*.pngThe quickest way to compile from source is to unpack the epplets source and then just copy the E-Power.c file into the main epplets directory.
E-Power.c source.
