当我为LFS 7.1“制作”glibc-2.14.1时出现以下错误.我使用ubuntu作为主机操作系统.

谁能告诉我该怎么办？
解决方法
对于glibc 2.15,我不得不像ks1322那样：
$../glibc2.15/configure CFLAGS =“ – O2 -U_FORTIFY_SOURCE -fno-stack-protector”
$make
-O2是恢复默认优化所必需的,这是避免许多故障所必需的.
-U_FORTIFY_SOURCE需要避免gcc ../sysdeps/unix/sysv/linux/syslog.c失败(在函数’__vsyslog_chk’中：[…]内联调用’syslog’失败)
-fno-stack-protector需要避免gcc […] elf / dl-allobjs.os libc_pic.a((init-first.os):(.data 0x0)的失败：’__ libc_multiple_libcs’的多重定义).
使用这些CFLAGS,我只得到一个警告(errlist.c计数133膨胀到GLIBC_2.12计数134(旧errno.h？)).
附：不使用黄金链接器(ld.gold,来自binutils-gold包)也非常重要,因为libc的配置会拒绝它.通过将/usr/bin/ld符号链接从ld.gold更改为ld.bfd可以轻松完成此操作.
