Error. Undefined symbol: pdsp::WhiteNoise::out_signal()

[steeley]

Using OF 0.11.2 on OSX Big Sur

if I patch a VAoscillator it works ok.
osc.out_sine() >> engine.audio_out(1);

if I have a WhiteNoise object called wNoise and do this instead, I get the compile error shown below:
wNoise.out_signal() >> engine.audio_out(1);

i don't have a mac with that OSX version for testing this issue, any PR for solving it are welcome

[steeley]

What software/OS version are you using?
I can try on a different machine maybe.

If you have a pDSP white noise example that you know is working I can try that.

At the moment i'm using Debian 11, i also have access to a window 10 machine (but not all the time). I still have to setup an OSX machine again. But i think it should be tested on osx because the error looks like an OSX specific linking error.

I found that patching the white noise through an amplifier or other module before patching to the output seems to
work without an error.
