I’m following a pdf tutorial on creating externals for PD and I'm compiling using gcc and the terminal. I believe there is another step afterward to get pd to recognize the object as an external but I can’t seem to find the info for os X.

gcc -c helloworld.c -o helloworld.o
ld -export_dynamic -shared -o helloworld.pd_linux helloworld.o -lc -lm

any info would be greatly appreciated.

best,
