build shared lib on macOS

 

• clang compiler
  • does not recognize GCC-specific -Wno-format-truncation
  • on Mac use .dylib extension instead of .so
  • Major number is located before the extension

ex.

On Linux

$(CC) $(CFLAGS) -shared $(LDFLAGS) -Wl,-soname -Wl,libxxx.so.$(LIBMAJOR) -o libxxx.so $(OBJECTS)

 

$(CC) $(CFLAGS) -dynamiclib -current_version $(LIBVER) $(OBJECTS) -o libxxx.$(LIBMAJOR).dylib
