uuidtest.c 



#include <stdio.h>
#include <uuid/uuid.h>

int main(int argc, char **argv){
  uuid_t uuid;
  char str[36];
  uuid_generate(uuid);
  uuid_unparse(uuid, str);
  printf("%s \n", str);
  return 0;
}



mac下 不需要 链接uuid库 
gcc uuidtest.c 

Linux 编译 链接uuid库
gcc uuidtest.c -luuid
uuidtest.c:3:23: 致命错误:uuid/uuid.h:没有那个文件或目录

yum install uuid uuid-devel
yum install libuuid libuuid-devel

gcc uuidtest.c -luuid 
编译ok

./a.out
