出現(xiàn)上面的錯誤，使用gcc 加選項-lrt解決。

?

錯誤：

[root@localhost myunp2]# gcc -lrt -o slot slot.c -lunpipc slot.c: 在函數(shù)‘main’中: slot.c:8:22: 錯誤：‘IPC_PRIVATE’未聲明(在此函數(shù)內(nèi)第一次使用)msqid=Msgget(IPC_PRIVATE,SVMSG_MODE|IPC_CREAT);^ slot.c:8:22: 附注：每個未聲明的標識符在其出現(xiàn)的函數(shù)內(nèi)只報告一次 In file included from slot.c:1:0: unpipc.h:153:21: 錯誤：‘MSG_R’未聲明(在此函數(shù)內(nèi)第一次使用)#define SVMSG_MODE (MSG_R | MSG_W | MSG_R>>3 | MSG_R>>6)^ slot.c:8:34: 附注：in expansion of macro ‘SVMSG_MODE’msqid=Msgget(IPC_PRIVATE,SVMSG_MODE|IPC_CREAT);^ unpipc.h:153:29: 錯誤：‘MSG_W’未聲明(在此函數(shù)內(nèi)第一次使用)#define SVMSG_MODE (MSG_R | MSG_W | MSG_R>>3 | MSG_R>>6)^ slot.c:8:34: 附注：in expansion of macro ‘SVMSG_MODE’msqid=Msgget(IPC_PRIVATE,SVMSG_MODE|IPC_CREAT);^ slot.c:8:45: 錯誤：‘IPC_CREAT’未聲明(在此函數(shù)內(nèi)第一次使用)msqid=Msgget(IPC_PRIVATE,SVMSG_MODE|IPC_CREAT);^ slot.c:11:22: 錯誤：‘IPC_RMID’未聲明(在此函數(shù)內(nèi)第一次使用)Msgctl(msqid,IPC_RMID,NULL);

解決方法：

1.unpv22e里面的Make.defines?
修改?
#CFLAGS = -g -O2 -D_REENTRANT -Wall?
CFLAGS = -g -O2 -D_GNU_SOURCE -D__USE_GNU -D_REENTRANT -Wall?

2 將unpv22e中的unpipc.h拷貝到需要編譯的代碼的目錄。

3 將config.h也拷貝到這個目錄，由于unpipc.h依賴于這個頭文件。
