我正在尝试编写一个在Micokernel和Monolithic系统上实现消息传递的应用程序。 这个代码在Linux上运行得很好，但在Denbian GNU / Hurd上失败
#include <sys/types.h> #include <sys/msg.h> #include <stdio.h> #include <string.h> #include <stdlib.h> #define MSGSZ 128 /* * Declare the message structure. */ typedef struct msgbufer { long mtype; char mtext[MSGSZ]; } message_buf; int main() { int msqid; int msgflg = IPC_CREAT | 0666; key_t key; message_buf sbuf; size_t buf_length; /* * Get the message queue id for the * "name" 1234, which was created by * the server. */ key = 1234; (void) fprintf(stderr, "\nmsgget: Calling msgget(%i,\ %#o)\n", key, msgflg); if ((msqid = msgget(key, msgflg )) < 0) { perror("msgget"); exit(1); } else (void) fprintf(stderr,"msgget: msgget succeeded: msqid = %d\n", msqid); /* * We'll send message type 1 */ sbuf.mtype = 1; (void) strcpy(sbuf.mtext, "Hello other process 2."); buf_length = strlen(sbuf.mtext) + 1 ; /* * Send a message. */ int err = msgsnd(msqid, &sbuf, buf_length, IPC_NOWAIT); if (err < 0) { printf ("%d, %li, %s, %lu\n", msqid, sbuf.mtype, sbuf.mtext, buf_length); perror("msgsnd"); exit(1); } else printf("Message: \"%s\" Sent\n", sbuf.mtext); exit(0); } 这是我得到的错误：
send.cpp: (.text+0xf9): warning: msgsnd is not implemented and will always fail send.cpp: (.text+0xf9): warning: msgget is not implemented and will always fail
任何想法？
