ofUtils.cpp:(.text+0x9f0c): undefined reference to `__atomic_fetch_add_8'

Hi, I am struggling to solve the problem.
I am installing openFrameworks 0.10.01 armv_6 on Raspberry pi 2, and trying to run an polygonExample.
However, I’ve got 2 Error like:

Linking bin/polygonExample for linuxarmv6l

I don’t know the solution.
Is anyone who know the problem?

Many Thanks.

This is likely due to the updated Raspbian OS Buster. To solve this problem, you need to link the “atomic” library. You can solve this temporarily by updating your project linker flags. To do this, follow the instructions here:

It works well ! I really appreciate to you!!:joy:

i install today of v0.11.0 armv6l in my rasberry pi. 3 with rasbian buster based.
also run the dependencies script successful.
I try to compile the empty example but i get a lots of undefined reference errors.
i also change add -latomic in the config but don’t works for me. like bebeam sugest!

Any help appreciate.

I JUST WANT CONFIRM THAT ADD -latomic IN THE config.make like bebem suggest. Working for my now.

hi @Juan can you post the command line steps you took to build the project and the errors you are getting?

Also, did you follow the instructions here?:
