Glibc 编译错误

Question

我正在 Ubuntu 10.10（VirtualBox 中的 32 位）中编译 glibc-2.12.1。遵循的步骤：

配置 --prefix=/usr --disable-asm
制作

[我正在从一个新目录构建它]

我在运行 make 上遇到以下错误：

我尝试使用 --disable-asm（在配置 --prefix=/usr --disable-asm 中）但它仍然给出相同的错误。

在 Google 上搜索发现这个问题已经存在很长时间了 [参考：http://comments.gmane.org/gmane.comp.lib.glibc.user/758]。

导致此错误的原因是什么以及如何解决？

问题是由您的 GCC 定义 __i686 引起的。您可以通过以下命令确认它实际上是这样做的：

gcc -dD -E -xc /dev/null | grep __i686

如果此命令产生输出，那就是问题所在。要修复它，请使用：

configure --prefix=/usr CC='gcc -U__i686'

或构建更新版本的 glibc。
