GCC 5.1.0-4 交叉编译器构建失败
GCC 5.1.0-4 cross compiler build fail
我正在学习 osdev.org 裸机教程，但我目前停留在 cross compiler.！我正在从 arch 发行版构建。
看来可能是isl的问题。我认为该教程是基于旧版本的 gcc、cloog、isl 等，所以在尝试了几次之后，我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，本教程说某些 cloog 和 isl 实现存在兼容性问题。我不知道那是针对我正在构建的机器还是针对目标，所以我只在我的主机上安装了 cloog，根据 the cloog page. ，它应该带有自己的嵌入式 isl！我是否还应该为构建过程安装另一个 isl（可能是 12.2？）？这甚至是我的问题吗？日志中有红色鲱鱼错误，所以我不确定我是否应该关注日志第 100 行的 libisl.so.13 错误。

这是我第一次没有找到我的答案，很抱歉任何新手海报问题。
我的理解是 gcc-5.x 不再需要 CLooG。建议您使用isl-0.14可用here or here. You might find the current (gcc-5.1) instructions at Linux from Scratch有帮助。毫无疑问，配置选项有 很多，因此很难知道构建的最佳选项，尤其是在构建 'stage 1' (独立式) gcc.
我正在学习 osdev.org 裸机教程，但我目前停留在 cross compiler.！我正在从 arch 发行版构建。
看来可能是isl的问题。我认为该教程是基于旧版本的 gcc、cloog、isl 等，所以在尝试了几次之后，我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，本教程说某些 cloog 和 isl 实现存在兼容性问题。我不知道那是针对我正在构建的机器还是针对目标，所以我只在我的主机上安装了 cloog，根据 the cloog page. ，它应该带有自己的嵌入式 isl！我是否还应该为构建过程安装另一个 isl（可能是 12.2？）？这甚至是我的问题吗？日志中有红色鲱鱼错误，所以我不确定我是否应该关注日志第 100 行的 libisl.so.13 错误。

这是我第一次没有找到我的答案，很抱歉任何新手海报问题。
我的理解是 gcc-5.x 不再需要 CLooG。建议您使用isl-0.14可用here or here. You might find the current (gcc-5.1) instructions at Linux from Scratch有帮助。毫无疑问，配置选项有 很多，因此很难知道构建的最佳选项，尤其是在构建 'stage 1' (独立式) gcc.
