How to compile shared lib with clang on osx

Question

source file

rsetti::fastidio { /tmp }-> cat foo.c

    #include 
    void ACFunction() {
      printf(\"ACFunction()\\n\");
      AGoFunction()         


        

Answer 1

By using:

-Wl,-undefined -Wl,dynamic_lookup

or

clang -shared -undefined dynamic_lookup -o libfoo.so foo.c

seems to maintain the same behaviour of GCC.
