I compile Pure Data sources with my plugin, I use the GitHub Pure Data repository (https://github.com/pure-data/pure-data).

I think the symbol is well exported :

nm camomile | grep s_signal
0000000000699a60 D _s_signal
000000000010c0c0 t _sys_signal

but I forget to give you the full error :

tried /Users/Pierre/GitHub/Camomile/Patches/freeverb~.pd_darwin and succeeded
verbose(4): /Users/Pierre/GitHub/Camomile/Patches/freeverb~.pd_darwin: dlopen(/Users/Pierre/GitHub/Camomile/Patches/freeverb~.pd_darwin, 10): Symbol not found: _s_signal

so what is the Pd-engine you use?
is it loaded before trying to load the external?
