GCC 5.1.0-4交叉编译器构建失败

我正在学习osdev.org裸机教程，而我目前还停留在！我在一个拱门发行版上建房

看起来这可能是isl的问题。我认为本教程基于较旧版本的gcc、cloog、isl等，因此在尝试了几次之后，我重新开始使用新的源代码，并将cloog和isl排除在源文件之外（教程说它们是可选的）

此外，本教程还指出，某些CLOG和isl实现存在兼容性问题。我不知道这是用于我正在构建的机器，还是用于目标机器，所以我只在我的主机上安装了cloog，据我所知，它应该自带了自己的嵌入式isl！我还应该为构建过程安装另一个isl（可能是12.2？）吗？这就是我的问题吗？日志中有一些令人费解的错误，所以我不确定我是否应该关注日志第100行的libisl.so.13错误

这是我第一次在搜索中找不到答案，对于noobie海报出现的问题，我深表歉意。

我的理解是，gcc-5.x不再需要

。建议您使用isl-0.14

available或。您可能会在网站上找到当前的（gcc-5.1）说明。毫无疑问，您知道有很多配置选项，因此很难知道适合您构建的最佳选项，尤其是在构建“阶段1”（独立式）gcc时
