error: ‘int64_t’ does not name a type

我在CodeBlock中编译工程没有出现问题，但是放到ubuntu上用自己写的Makefile make的时候报错

error: ‘int64_t’ does not name a type

#
   2 # Makefile

   6 #define
   7 CC=gcc
   8 CXX=g++
   9 TARGET=TestPthreadDemo
  10 #CXXFLAGS = -std=c++11
  11 CXXFLAGS =
  12
  13 #files
  14 objects = TestPthreadDemo.o MultilPthread.o
  15 headers = MultilPthread.h
  16
  17 #rules
  18 $(TARGET): $(objects)
  19         $(CXX)  $(CXXFLAGS) $^ -o $@
  20
  21 %.o: %.cpp $(headers)
  22         $(CXX) -c $(CXXFLAGS) $< -o $@
  23
  24 .PHONY : clean
  25 clean :
  26         rm $(objects)
  27
  28 distclean:
  29         rm $(TARGET) 

需要添加头文件
#include <stdint.h>
