NFC on linux |undefined reference to `nfc_init'|

#1

hi everyone and happy coding to you all !

i am trying to build a little program, by using ofxNFCReader… on Linux
and i did everything to deal with it (correctly i think), Codeblocks keep saying this to me:

can you told me where is the problem? i a bit new in Linux, and it looks quite difficult to me :frowning:

thank you for your patience and have a happy day :slight_smile:

#2

seems like that addon only has the 32bit linux version of libnfc, you can just install it in the system using:

sudo apt-get install libnfc-dev

#3

Thank for your reply… but… it still not working: it is making the same errors. :frowning:

#4

you’ll probably need to add:

PLATFORM_CFLAGS=-lnfc -lusb

in your projects config.make

#5

still the same problem…
do you think i missed something when i install this libs, like :
acscssid-1.0.8
libusb-1.0.9
pcsc-lite-1.5.3

this is what i had to install to make it work normally. maybe it come from here ? (noob in linux)
