digitalWrite(pttPin,LOW); returns error undefined reference to `digitalRead'

[UgoPoddine]

Hi Adolfo,

thank-you for the porting of WiringPI in ARM64 envirnment.
The basic use runs very well.
Unfortunately I'm, finding an issue in compiling a small C++ daemon that performs very basic WiringPI activity (e.g. setting GPIO....)
The 32bit version runs well, buy on the ARM64 system the same compiled version can not be executed due to ELF64 problem.
I have tryed to recompile in the 64bit environment, bur the compilation returns error undefined reference to `digitalRead'.
You porting has been installed on a PI3+ usind the .deb file.

Ant help appreciated
Best regards
Ugo
