现undefined reference to `__gnu_mcount_nc'的解决

在编译内核时出现了如下错误:

上网参阅以下两个网页,

http://forum.ubuntu.org.cn/viewtopic.php?t=333083http://blog.sina.com.cn/s/blog_7d3976fc01012itz.html得出解决方法:

在网上下载一个补丁文件:地址如下:

www.arm9home.net/job.php?action-download-pid-37009-tid-7318-aid-1431.html

方法一,下载到Linux内核目录下,然后gunzip -dc __gnu_mcount_nc_patch.patch.gz |patch -p1


方法二,下载之后放在linux根目录下,并解压得到:__gnu_mcount_nc_patch.patch 文件。

然后,在终端进入linux根目录,执行以下语句进行打包:

zcat __gnu_mcount_nc_patch.patch | patch p1 或者 

 (注意:“__”为两个下划线连在一起,“p1”后面的是阿拉伯数字1,还要注意空格)

再重新编译就好了
