Yes, I did follow this instruction on both x86 and ARM

To build/install there is a new simplified script:

$ cd ~/wiringPi
$ ./build

The new build script will compile and install it all for you – it does use the sudo command at one point, so you may wish to inspect the script before running it.


I just do not get where the "lib" prefix came from.

I am still not too comfortable with Linux files scheme so I may be "linked" to wrong place.


I need to study "make" to get better idea how compiler does "build" and where all those "includes" come from.

For example how does "include /usr/local/include " translates to "/home/pi/wiringPi/wiringPi"?
Or does it ?

Stand by , I'll come back after I take a closer look at compiler and make.

Thanks for your help.
Vaclav



FYI here is what is in directory and apparently the *.h file in question is "included" but I see only "libwiringPi.so.2.44" file.
