我有一箇舊的程序，從一個客戶端，1個服務器寫的超級基本的'聊天'程序在C中，代碼如下。我正在嘗試將它編譯爲angstrom（運行在ARM芯片上），並且正在獲取這些錯誤。我安裝了angstrom工具鏈，是否需要特殊版本的sys/socket.h（或不同的頭文件，忘記了讀/寫/關閉函數所在的頭文件）等等。客戶端服務器程序的手臂開發
錯誤：
~/Desktop/test $ arm-angstrom-linux-gnueabi-g++ main.c -o main -lnsl
main.c: In function 'int main()':
main.c:66: error: invalid conversion from 'int*' to 'socklen_t*'
main.c:66: error: initializing argument 3 of 'int accept(int, sockaddr*, socklen_t*)'
main.c:75: error: 'read' was not declared in this scope
main.c:77: error: 'write' was not declared in this scope
main.c:79: error: 'close' was not declared in this scope
main.c:81: error: 'unlink' was not declared in this scope
我直接複製從類的代碼，所以第一個錯誤可能只是一些愚蠢的，但最近一說，他們甚至不能找到很多我需要的功能...但不知何故，它承認接受命令，並告訴我我使用了錯誤的論點：/任何想法？
代碼：
#include <stdio.h>
#include <stdlib.h>
#include <sys/types.h>
#include <sys/socket.h> /* define socket */
#include <netinet/in.h> /* define internet socket */
#include <netdb.h> /* define internet socket */
#define SERVER_PORT 9999 /* define a server port number */
int main()
{
int sd, ns, k;
struct sockaddr_in server_addr = { AF_INET, htons(SERVER_PORT) };
struct sockaddr_in client_addr = { AF_INET };
int client_len = sizeof(client_addr);
char buf[512], *host;
/* create a stream socket */
if((sd = socket(AF_INET, SOCK_STREAM, 0)) == -1)
{
perror("server: socket failed");
exit(1);
}
/* bind the socket to an internet port */
if(bind(sd, (struct sockaddr*)&server_addr, sizeof(server_addr)) == -1)
{
perror("server: bind failed");
exit(1);
}
/* listen for clients */
if(listen(sd, 1) == -1)
{
perror("server: listen failed");
exit(1);
}
printf("SERVER is listening for clients to establish a connection\n");
if((ns = accept(sd, (struct sockaddr*)&client_addr,
&client_len)) == -1)
{
perror("server: accept failed");
exit(1);
}
printf("accept() successful.. a client has connected! waiting for a message\n");
/* data transfer on connected socket ns */
while((k = read(ns, buf, sizeof(buf))) != 0)
{ printf("SERVER RECEIVED: %s\n", buf);
write(ns, buf, k);
}
close(ns);
close(sd);
unlink(server_addr.sin_addr);
return(0);
}
