6 years ago The libraries are there but the PATH for LDLIBRARYPATH is missing.
You can temporarily set the PATH with export:
export LD_LIBRARY_PATH=$LD_LIBRARYPATH:/opt/vc/lib
To make the changes permanent add the export command to a file in /etc/profile.d/.
In order to run /opt/vc/bin/vcgencmd as lepidopter, you should add the user lepidopter to the video group.
Another way to get the current temperature without using any program is to read the content of the file /sys/class/thermal/thermal_zone0/temp you can pretty print the temperature:
echo $((`cat /sys/class/thermal/thermal_zone0/temp|cut -c1-2`)).$((`cat /sys/class/thermal/thermal_zone0/temp|cut -c3-5`))Thank you for reporting this.
I was trying to check the Raspberry Pi's temp during the test, but it seems that a couple of libraries are missing from the distribution.
