ELF relocation 问题

[sunshine-cdl]

孙老师您好，我在使用您2021/6的工具链编译其他软件时遇到了如下问题：

我完全无法解决这个问题。它似乎有点过于底层，而且是由目标软件编译过程中一个非常非常庞大的命令引发的，因此它变得十分不可控……希望您能以专业人士的视点给出一些建议，不胜感激。

我也不是很清楚你碰到的问题，不过你是在编译GHC时侯碰到的吧？ 为此我去编译了一下GHC，没有遇到你出现的问题。

老师您好，我就是提问者，现在是用另外一个账号 我们使用的工具链是gcc8.3/glibc2.28/binutils2.31那一版，编译的是ghc9.5 这个问题发生在最后的链接阶段，构建交叉编译器是没问题的 另外，我们在使用gcc12/glibc2.35那一版工具链时不会出现这个问题，烦请您再帮我们看看

[sunhaiyong1978]

也可能是gcc8.3这组工具链不匹配导致的。
