Shell execute error

---

does anybody have some idea as to what could be causing this:

ShellActionHandler: stderr output from command gpio write 6 1: gpio: Symbol `piModelNames’ has different size in shared object, consider re-linking

error when executing this:

execute “gpio write 6 1” and after 10 seconds execute “gpio write 6 0”

rule??

Looks like any commands to Wiringpi gets this error…

@Hubald-Alberti
tried with `execute “sudo gpio write 6 1” … ?
dont know if this matters at all

at the bash the command is working?

Seems like a dependency problem where different versions of WiringPi linked libraries are loaded somehow. Do you have multiple versions of WiringPi installed? If understand this correctly it refuses the execution of wiringPi command, right? Does it behave the same way if you execute from the command line?

See also http://stackoverflow.com/questions/15054973/c-symbol-has-different-size-in-shared-object for a general explanation of the matter.

From commandline it functions as hoped, it switches on-/off the pin 6.

The mentioning of multiple versions of Wiringpi makes me realise this could be the culprit. I recently had to do a complete reinstall of Pimatic because i cripp;ed the system trying to get my neopixels to work…
Using the installer i installed Wiringpi (easy!) but after puutting back my old configfile i ran into some problems with wiringpi and i (re-)installed it.

Could this be it??!!
Thanks for the help everyone, i really love this program and just getting on the learning-curve

Well maybe. The installer will install wiringpi to /home/pi/wiringpi
the Installation routine checks if wiringpi is installed at /home/pi/wiringpi. If exists the installation will be canceled.
If not exists it will install.
