I'm running Pd-0.52-2 on MacOS Monterey (12.6) and having trouble with externals that I created. When developing/debugging, everything is fine. I have 4 externals with extensions .pd_darwin, each dependent upon a DLL named libo2pd.dylib. With everything in ~/Documents/Pd/externals/, I can start my locally compiled pd-0.52-2.app, and everything works. But if I run a downloaded /Applications/Pd-052-2.app and try to create one of these external objects, I get the message:
/Users/rbd/Documents/Pd/externals/o2ensemble.pd_darwin: dlopen(/Users/rbd/Documents/Pd/externals/o2ensemble.pd_darwin, 0x000A): Library not loaded: 'libo2pd.dylib' Referenced from: '/Users/rbd/Documents/Pd/externals/o2ensemble.pd_darwin' Reason: tried: 'libo2pd.dylib' (relative path not allowed in hardened program), '/usr/lib/libo2pd.dylib' (no such file) o2ensemble o2global ... couldn't create
I get the same results running from the command line, and running from the directory with the .dylib and externals does not make any difference. Note that /usr/lib is protected even using sudo, so even if I could install libo2pd.dylib there, I don't think it's an acceptable solution.
I suspect this problem stems from Apple security policies, but I don't know how Pd searches for .dylibs and there's a lot of ambiguity in documentation and discussions since "libraries" and "paths" are used in multiple ways. I also tried setting LD_LIBRARY_PATH and running from the command line, but that didn't work.
Does anyone know to set up Pd for an external that depends on a DLL?
