（原标题为：求解：一个菜鸟编程中的问题！） 编写了一个shell命令cp 代码如下： #include #include #include #include #define maxOnce 1024 int main(int argc,char * argv[]) { int fdsrc,fddist; char buf[maxOnce]; char buf1[maxOnce]; int size; if(argc!=3) printf("error for input\n"); if((fdsrc=open(argv[1],O_RDONLY)==-1) perror("error for open\n ");//出错...

在Suse11.0上用交叉编译器xscale-linux-gcc编译一个库，出现如题的错误： “ xscale-linux-gcc -O2 -fPIC -I. -I ../../kernel -I ../lib -DHAVE_CONFIG_H -D_U_="__attribute__((unused))" -c bpf_filter.c bpf_filter.c:1: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘.’ token make: *** [bpf_filter.o] Error 1 ” bpf_filter.c文件的内容就一行： link ./bpf/net/bpf_filter.c 我一直用...

我想给我的cnetos 5.1的iptables增加ipp2p功能，linux内核版本2.6.18-53.el5，iptables版本为1.3.5，现在我从网上下载了kernel为2.6.18.8的源码包，iptables仍为1.3.5源码，patch-o-matic-ng-20071120。给内核打补丁，在内核的配置文件中选择ipp2p为模块， 1。make modules_prepare 2.make M=net/ipv4/netfilter 出错： CC [M] net/ipv4/netfilter/ipt_ipp2p.o net/ipv4/netfilter/ipt_ipp2p.c:749: 错误：expected declarati...

错误具体如下： shell.c: In function ‘main’: shell.c:40: 错误：expected expression before ‘char’ shell.c:40: 错误：提供给函数 ‘setup’ 的实参太少 这个是第四十行代码： setup( char inputBuffer[],char *args[ ] ,int *background); 函数定义如下： void setup(char inputBuffer[ ],char *args[ ] ,int *background) ｛ ...... ...... ...... ...... ｝

error: expected declaration specifiers or ‘...’ before ‘foo’ Hey guys. I am trying to implement a system call in linux kernel. I usually use ubutntu, but this I am doing on Fedora. I am using kernel 2.6. Here is what I did: 1. Added a line to arch/i386/kernel/syscall_table.S: .long sys_foo 2. Added a line to linux/include/asm-i386/unistd.h: #define __NR_foo 324 also incremented the call ...
