編譯在Ubuntu的rpcgen程序

我是rpcgen編程的新手。在編譯ubuntu上下面的示例的rpcgen例如我得到和error.The主要功能是計算在給定數量編譯在Ubuntu的rpcgen程序

的平方square.X

struct square_in { 
long arg1; 
}; 

struct square_out { 
long res1; 
}; 

program SQUARE_PROG { 
version SQUARE_VERS { 
square_out SQUAREPROC(square_in) = 1; 
        /* procedure number = 1 */ 
} = 1;    /* version number = 1 */ 
} = 0x31230000;   /* program number = 0x31230000 */

client.c

#include <rpc/rpc.h> 
    #include "square.h" 

int 
main(int argc, char **argv) 
    { 
CLIENT  *cl; 
square_in in; 
square_out *outp; 

if (argc != 3) 
    //err_quit("usage: client <hostname> <integer-value>"); 
    exit(0); 

cl = clnt_create(argv[1], SQUARE_PROG, SQUARE_VERS, "tcp"); 

in.arg1 = atol(argv[2]); 
if ((outp = squareproc_1(&in, cl)) == NULL) 
    //err_quit("%s", clnt_sperror(cl, argv[1])); 
    exit(0); 

printf("result: %ld\n", outp->res1); 
exit(0); 
}

server.c

#include <rpc/rpc.h> 
#include "square.h" 
#include <stdio.h> 


    square_out * 
    squareproc_1_svc(square_in *inp, struct svc_req *rqstp) 
    { 
static square_out out; 

printf("thread %d started, arg = %ld\n", 
     pr_thread_id(NULL), inp->arg1); 
sleep(5); 
out.res1 = inp->arg1 * inp->arg1; 
printf("thread %d done\n", pr_thread_id(NULL)); 

return(&out); 
     }

生成文件：

PROGS = client server 
CFLAGS += -DDEBUG 

all: ${PROGS} 

square.h square_clnt.c square_svc.c square_xdr.c: square.x 
      rpcgen -C square.x 

square_clnt.o: square_clnt.c square.h 

square_svc.o: square_svc.c square.h 

client: square.h client.o square_clnt.o square_xdr.o 
      ${CC} ${CFLAGS} -o [email protected] client.o square_clnt.o square_xdr.o \ 
       ${LIBS} ${LIBS_RPC} 

server: square.h server.o square_svc.o square_xdr.o 
      ${CC} ${CFLAGS} -o [email protected] server.o square_svc.o square_xdr.o \ 
       ${LIBS} ${LIBS_RPC} 

clean: 
     rm -f ${PROGS} ${CLEANFILES} *_clnt.c *_svc.c *_xdr.c square.h

在執行時，我得到以下錯誤：

cc -DDEBUG -c -o client.o client.c 
cc -DDEBUG -o client client.o square_clnt.o square_xdr.o \ 

cc -DDEBUG -c -o server.o server.c 
cc -DDEBUG -o server server.o square_svc.o square_xdr.o \ 

server.o: In function `squareproc_1_svc': 
server.c:(.text+0x14): undefined reference to `pr_thread_id' 
server.c:(.text+0x52): undefined reference to `pr_thread_id' 
collect2: error: ld returned 1 exit status 
make: *** [server] Error 1

我不認爲你需要使用pr_thread_id。嘗試編譯沒有它。

使用服務器上的文件就像使用

[[email protected] ~]# rpcgen -C square.x 
[[email protected] ~]# cc -c client.c -o client.o 
[[email protected] ~]# cc -c square_clnt.c -o square_clnt.o 
[[email protected] ~]# cc -c square_xdr.c -o square_xdr.o 
[[email protected] ~]# cc -o client client.o square_clnt.o square_xdr.o 
[[email protected] ~]# cc -c client.c server.c square_xdr.c 
[[email protected] ~]# cc -c server.c -o server.o 
[[email protected] ~]# cc -c square_svc.c -o square_svc.o 
[[email protected] ~]# cc -o server server.o square_svc.o square_xdr.o 
[[email protected] ~]# ./server & 

[1] 3334 

[[email protected] ~]# ./client localhost 4 

result is : 16

這

// SERVER FILE: server.c 

#include"rpc/rpc.h" 
#include"square.h" 
#include"stdio.h" 
#include"stdlib.h" 
#include"math.h" 

square_out *squareproc_1_svc(square_in *inp,struct svc_req *rqstp) 
{ 

    static square_out out; 
    out.res1 = inp->arg1 * inp->arg1; 
    return(&out); 
}

和運行程序
