定义enum 在多个文件类中使用，编译报错

[yuanzhenhai]

如题：
我在main.h中定义了

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <sys/types.h>

#include <iostream>
#include <string>
using namespace std;
using std::string;

#include "file1.h"
#include "file2.h"

typedef enum _SOURCESTREAM_STATE
{
	SOURCESTREAM_INVALID = -1,
	SOURCESTREAM_INIT = 0,
	SOURCESTREAM_START = 1,
	SOURCESTREAM_STOP = 2,
}SOURCESTREAM_STATE;

在file1.h中声明函数如下：

#include "main.h"
void file1_funtion(SOURCESTREAM_STATE state);

在file1.cpp中定义函数如下：

#include "file1.h"
void file1_funtion(SOURCESTREAM_STATE state)
{
	if (state == SOURCESTREAM_START)
	{
		printf("[%s][%d][%s]\n", __FILE__, __LINE__, __func__);
	}
}

file2.h file2.cpp与file1.h file2.cpp差不多，只是函数名不一样， 编译报错如下：
realtimedsp@realtimedsp-desktop:~/test/2014_test/enum$ make
g++ -c -g -DDEBUG -lpthread file1.cpp
In file included from main.h:16:0,
from file1.h:5,
from file1.cpp:3:
file2.h:7:20: error: variable or field ‘file2_funtion’ declared void
file2.h:7:20: error: ‘SOURCESTREAM_STATE’ was not declared in this scope
make: *** [file1.o] Error 1

请多多指教！！

本来是有类的，但是在没类也报错是，所以应该与类无关，Makefile如下： TARGET = $(notdir $(CURDIR)) #TARGET = test CC = g++ #CC = /opt/arm-2009q1/bin/arm-none-linux-gnueabi-gcc PATH1 = /usr/local #PATH1 = /usr/local_arm USER_LIB = $(PATH1)/lib USER_INCLUDE = $(PATH1)/include INCLUDE = -I $(USER_INCLUDE) ##INCLUDE += -I /usr/include/c++/4.6 LIB = -L $(USER_LIB) ##LIB += -L /usr/lib64 C_FLAGS = -g -DDEBUG -lpthread RM = rm SOURCES = $(wildcard *.cpp) HEADERS = $(wildcard *.h) OBJFILES = $(SOURCES:%.cpp=%.o) # stdsoap2.o SERVER_OBJS = $(OBJFILES) .PHONY: clean all: $(TARGET) $(TARGET): $(SERVER_OBJS) $(CC) -o $(TARGET) $(SERVER_OBJS) $(INCLUDE) $(LIB) $(C_FLAGS) %.o: %.cpp $(CC) -c $(C_FLAGS) $< clean: @echo Removing generated files.. rm -f *.o $(TARGET) $(OBJFILES) *.log

main.h和file1.h互相include？这可不太好吧

[brookmill]

能不能把main.h里面这两行删掉 #include "file1.h" #include "file2.h"

感谢brookmill，是include问题
