Interface & Abstract

Last Update: 2016/09/07 21:42+08



Assume
that with interface you mean a C++ class with only pure virtual methods (i.e. without any code),
instead with abstract class you mean a C++ class with virtual methods that can be overridden, and some code, but at least one pure virtual method that makes the class not instantiable.

class MyInterface
{
public:
  // Empty virtual destructor for proper cleanup
  virtual ~MyInterface() {}

  virtual void Method1() = 0;
  virtual void Method2() = 0;
};


class MyAbstractClass
{
public:
  virtual ~MyAbstractClass();

  virtual void Method1();
  virtual void Method2();
  void Method3();

  virtual void Method4() = 0; // make MyAbstractClass not instantiable
};

fatal error: socal/socal.h: No such file or directory
修正makefile, 將下面這行

CFLAGS = -static -g -Wall  -I${SOCEDS_DEST_ROOT}/ip/altera/hps/altera_hps/hwlib/include

取代成

ALT_DEVICE_FAMILY ?= soc_cv_av
HWLIBS_ROOT = ${SOCEDS_DEST_ROOT}/ip/altera/hps/altera_hps/hwlib
CFLAGS = -static -g -Wall $(MULTILIBFLAGS) -I${HWLIBS_ROOT}/include -I${HWLIBS_ROOT}/include/soc_cv_av -D$(ALT_DEVICE_FAMILY)
