Hi All.
This is my first post on the forum.
I recently obtained Raspberrypi 4 B
I have installed
libgpiod-dev Version 1.6.3-1+rpi1+b2
libgpiod Version 1.6.3-1+rpi1+b2
I'm using vcode via ssh and was able to create and compile simple "Hello World" application on Raspberrypi.
I decided to go one step further and wanted to use libgpiod
this is my modified programI'm building it with vcode as i did previously with simple application but with addition of -lgpiodcxx.
And this is the terminal output
Starting build...
