c - 错误 : expected ‘=’ , ‘,’ , ‘;’ , ‘asm’ 或 ‘__attribute__’ 数字常量前

Question

我遇到了错误src/sr_main.c:在函数“main”中:src/sr_main.c:72: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘attribute’ 数字常量src/sr_main.c:72: 警告:语句无效src/sr_main.c:81: error: ‘natEnabled’ undeclared (first use in this function

我不知道为什么会出现此错误。一切似乎在语法上都是正确的。

59 int main(int argc, char **argv)
 60 {
 61   int c;
 62   char *host   = DEFAULT_HOST;
 63   char *user = 0;
 64   char *server = DEFAULT_SERVER;
 65   char *rtable = DEFAULT_RTABLE;
 66   char *filter = DEFAULT_FILTER;
 67   char *template = NULL;
 68   unsigned int port = DEFAULT_PORT;
 69   unsigned int topo = DEFAULT_TOPO;
 70   char *logfile = 0;
 71   struct sr_instance sr;
 72   int natEnabled 0;
 73 
 74   printf("Using %s\n", VERSION_INFO);
 75 
 76   while ((c = getopt(argc, argv, "hs:n:v:p:u:t:r:l:T:")) != EOF)
 77   {
 78     switch (c)
 79     {
 80     case 'n':
 81       natEnabled =1;
 82       break;
 83     case 'h':
 84       usage(argv[0]);
 85       exit(0);
 86       break;

是的，听编译器，你需要int natEnabled=0;
