[Csnd-dev] Building example CPOF plugin opcodes

Hi!

I'm trying to build the example CPOF plugin opcodes (develop branch) on 
MacOS using:

gcc -O2 -dynamiclib -o opcodes.dylib opcodes.cpp 
-I/Users/mesca/Library/Frameworks/CsoundLib64.framework/Headers 
-std=c++11 -DUSE_DOUBLE

Unfortunately, I have a bunch of unresolved symbols, including:

opcodes.cpp:73:13: error: no member named 'plugin_deinit' in 'csnd::Csound'
     csound->plugin_deinit(this);
     ~~~~~~  ^
opcodes.cpp:138:36: error: no member named 'sr' in 'csnd::Csound'
     delay.allocate(csound, csound->sr() * inargs[1]);

Also, using csound->init_error()/message()/... result in:

ld: symbol(s) not found for architecture arm64

What am I missing?
