I have received the code now but the project contained in the zip does
not build on my RPi3 with Raspbian and Lazarus 1.6 FPC 3.0.

I get the following error message:

Compile Project, Target: x_pigpiod_if2: Exit code 256, Errors: 1
/usr/bin/ld: warning: link.res contains output sections; did you
forget -T?
/usr/bin/ld: cannot find -lpigpiod_if2
x_pigpiod_if2.lpr(21,0) Error: Error while linking

The file it complains about is pigpiod_if2 and is not contained in the
zipfile. But there is a pigpiod_if2.pas file that seems to define a
lot of functions contained in a file with this name...
I do not know if it is an external binary library, which must be
supplied or where it resides.
