Cannot run program "/opt/vc/bin/vcgencmd"

[anakin59490]

Hi,

I try to retrieve Info System like the example : https://github.com/Pi4J/pi4j-v1/blob/master/pi4j-example/src/main/java/SystemInfoExample.java

But I get the following error: Cannot run program "/opt/vc/bin/vcgencmd"

because vcgencmd is in "/usr/bin/"

How can I solve that ?

Thank you in advance
