expected declaration specifiers or ‘...’ before ‘gssize
我安装mysql-proxy遇到了<em>expected</em> <em>declaration</em> <em>specifiers</em> or ‘...’ before ‘gssize这个问题,搜了一下说是要修改rnlinux系统头文件的问题,不知道怎么解决,求解
expected declaration specifiers or '...' before 'fd_set'
<em>expected</em> <em>declaration</em> <em>specifiers</em> or '...' before 'fd_set'rnrn我<em>编译</em>c程序,和一个外部libcurl的a文件,就出这个错,是什么原因?
求助,报错expected declaration specifiers or '...'before show_sys_call
在做系统调用的内核修改,其中有个c文件代码如下:rn#includern#includern#includern#includern#define _ _NR_show_sys_call 297rn_syscall1(int¸show_system_call¸int¸system_callno)rnmain()rn int i ¸n;rn printf("Enter No:"); rn scanf("%d"¸&i);rn n= show_sys_call(i);rn if(n!=-1)rn printf("system call --.%d has been called %ld times!\n"¸i¸n);rnrnrnrn在终端执行gcc sys_show_system_call.c -o show.out的时候报的错。rn查了资料看了网上其他网友说的,改成了g++,报错就为show_system_call未声明和<em>expected</em> constructor,destructor,or type conversion before ; token 等等。rn求教各位大侠。。。rnrnrn其他还有两个c文件,分别是sys_list_system_call和sys_clear_system_call,报的错都和这个一模一样。。。
