这个编译时-N选项的错误怎么解决？

zalem

debian:~/c# gcc -N a.c
/usr/bin/ld: cannot find -lgcc_s
collect2: ld returned 1 exit status

但是这样就可以
debian:~/c# gcc -c -N a.c
debian:~/c# gcc a.o



---edit---

debian:~/c# gcc -c -N a.c
debian:~/c# gcc -N a.o
也是同样的错误，请问gcc_s是个什么库？

这个是man ld里面的

       -N
       --omagic
           Set  the  text and data sections to be readable and writable.  Also, do
           not page-align the data segment, and  disable  linking  against  shared
           libraries.   If  the  output  format supports Unix style magic numbers,
           mark the output as "OMAGIC". Note: Although a writable text section  is
           allowed for PE-COFF targets, it does not conform to the format specifi-
           cation published by Microsoft.

和我看的linux-doc gcc-faq里面说的不大一样，结果想试试就那样了...

-N应该是给连接器用的。表示不连接动态库

谢谢
试了下，redhat8下面就没有问题，算了，也不急着用，估计什么时候能碰到解决方法的文章

-N是ld的选项，手册上说加入它，则不链接共享库。但既然如此，似乎就不该调用ld或collect2，就象gcc的-c选项一样。
