undefined symbol: wiringPiSetup #1

My apologies if I am asking this in the wrong place, but i have reached a complete dead end!

I am using a library called node-rcswitch which is reliant on WiringPi.

I am running my project off of a NanoPi NEO so have installed WiringNP as a replacement for WiringPi. node-rcswitch uses the -lwiringPi flag when compiling and does so without error.

However, when i come to use it at run time i get the following error: undefined symbol: wiringPiSetup

Am i missing something with regards to WiringNP? As far as i understand it, WiringNP can be used in exactly the same way as WiringPi. I just can't figure out why its not working at runtime. =(

You can check examples/gpio makefiles to see how to add libraries / define compiler options for proper compilation. Please let me know if it helps

Unfortunately that doesn't help. Like i said, the program is compiled with the -lwiringPi flag, and i have even tried with all the flags listed in the examples here. The script calls the wiringPiSetup function at the beginning. Yet i still get that error =(
