Linux 关于交叉编译器的正确配置，我应该参考哪些内容？

对于交叉编译器的配置，我已经参考了“readelf-htarget.bin”（target.bin在目标机器上运行）的输出。我假设由交叉编译器编译的二进制程序的readelf输出应该与target.bin的输出相同

但是，在以下情况下，两个相互具有不同“readelf”输出的程序可以在目标机器上成功运行。此外，另一个readelf输出与target.bin的输出类似的程序在目标机器上不可执行。看起来readelf输出对于交叉编译器的配置并不重要。 然后。。。要为目标机器正确配置交叉编译器，我应该参考哪些内容？

例子： readelf-h target.bin（target.bin是在目标机器上运行的二进制程序）输出：

readelf-h myfail_target.bin（由我编译），在目标计算机上不可执行，输出：

任何评论都将不胜感激。

首先让我印象深刻的是，您的工作代码有

mips32

，但后来我意识到您的顶级示例没有，所以这确实有点令人困惑！（这是你的另一个问题中的hello world程序吗？你可能想在这里发布它，以及其他人看到的编译器命令行和版本）PS我可以理解你在这里的挫折感，我讨厌它，因为有些东西本来就应该行得通，而在我的情况下，通常都很有效，突然之间没有了……我做了一些进一步的挖掘，发现了一些关于2.4.x内核和MIPS ELF中的bug的讨论，尽管这可能只是偶然的，如果您的非工作/工作软件运行在较新的内核上。我想知道小精灵是否真的和它有任何关系。。。这可能更像是一种编译器特性。例如，在调试（非优化）编译和优化编译中，您是否会遇到相同的错误？静态链接和动态链接怎么样？
