[Gambas-user] Shared WiringPi library for RasPi

[CJ]

After compiling and updating to latest stable 3.4.1 version I retested
the HW interrupt code I had problems with when running 3.3.4 and have the
same error when testing on the RaspberryPi...

Code compiles OK but when I pull GPIO18 pin low (i.e generating the
interrupt)
it crashes with a "Stack overflow" error message.

  root at ...3122...:/home/Projekt/libwiringPi_irq# ./libwiringPi_irq.gambas
  wiringPi Init OK...

Below is the output from gdb...

A informed by Benoît this is how to declare it in Gambas3 to use the
interrupt
function in wiringPi library...

Pointer) In "lib..."

>directly like a C function.

As mentioned before problem may very well be in my code when setting up the
interrupt handler, attached is the source code and wonder if I'm doing it
correctly by placing the interrupt handler in a separate classfile so any
pointer
appreciated...
