Answer 1

看来 crosstool-ng 使用的 mpfr 版本与您的 autoconf 版本不兼容。我建议尝试更新版本的 crosstool-ng（1.19 版于 2013 年发布）。

如果你真的需要crosstool-ng 1.19，你可以尝试从"Companion tools"编译autoconf版本（必须设置EXPERIMENTAL）。

您也可以尝试安装另一个版本的autoconf。我相信 Ubuntu 14.04 提供了 autoconf 2.13、2.59 和 2.68。你可以试试。

Answer 2

解决方案： 问题是我的 mpfr 版本...所以为了修复我用 ./-ct-ng menuconfig 配置的问题，我告诉他 重建这个模块 。它位于 配套库 .
