我刚刚开始在 ubuntu (9.04) 下使用 gcc 编写 ansi c。我收到以下错误消息：

错误信息：

main.c:6: error: expected identifier or ‘(’ before ‘/’ token
In file included from /usr/include/stdio.h:75,
                 from main.c:9:
/usr/include/libio.h:332: error: expected specifier-qualifier-list before ‘size_t’
/usr/include/libio.h:364: error: expected declaration specifiers or ‘...’ before ‘size_t’
/usr/include/libio.h:373: error: expected declaration specifiers or ‘...’ before ‘size_t’
/usr/include/libio.h:493: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘_IO_sgetn’
In file included from main.c:9:
/usr/include/stdio.h:314: error: expected declaration specifiers or ‘...’ before ‘size_t’
/usr/include/stdio.h:682: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘fread’
/usr/include/stdio.h:688: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘fwrite’
main.c:12: error: expected identifier or ‘(’ before ‘/’ token

我认为这是一个非常简单的问题，可能在 ubuntu 或 gcc 的配置中。我也是linux下编程的新手。我搜索了帮助并浏览了教程，但找不到答案。谢谢！

代码： 

/* cheat with the preprocessor to skip over missing lines to attempt
   to duplicate the circumstance of the original code */
#line 9
// #include <some_random_header.h>
#include <stdio.h>
#include <math.h>    
int main(int argc, char **argv)
    {
     printf("TestOutput\n");

     return (0);
    }

命令：

~/Documents/projects/Trials$ gcc -Wall -ansi main.c

你真的确定你显示的代码就是你实际编译的代码吗？你得到错误：

main.c:12: error: expected identifier or ‘(’ before ‘/’ token

但代码实际上并没有 12 行。

我使用“//”来注释行，这是 ansi-c 不喜欢的。谢谢大家的意见！
