为了正确配置交叉编译器，我应该参考哪些内容？

Question

我已经提到了＆＃34; readelf -h target.bin＆＃34;的输出。 （target.bin在目标机器上运行）用于交叉编译器的配置。我假设交叉编译器编译的二进制程序的readelf输出应该与target.bin相同。

但是，在下面的例子中，两个程序有不同的＆＃34; readelf＆＃34;彼此的输出可以在目标机器上成功运行。此外，另一个具有类似readelf输出到target.bin输出的程序在目标机器上不可执行。似乎readelf输出对于交叉编译器的配置并不重要。 那么......为了正确配置目标机器的交叉编译器，我应该参考哪些内容？

实施例

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