GDB不会阅读外国架构核心文件 [英] gdb won't read core file from foreign architecture

问题描述

我想读我的Linux桌面上的ARM内核文件，但它似乎没有能够找出我的核心文件。有什么办法，我可以指导GDB什么类型我的核心文件？

I'm trying to read an ARM core file on my Linux desktop, but it seems not to be able to figure out my core file. Is there any way I can instruct gdb what type my core file is?

$ file ~/daemon
./daemon: ELF 32-bit LSB executable, ARM, version 1, dynamically linked (uses shared libs), for GNU/Linux 2.0.0, not stripped
$ file ~/core
./core: ELF 32-bit LSB core file ARM, version 1 (SYSV), SVR4-style, from './daemon -v -v -v -v -e 10 -t foo'
$ gdb-multiarch ~/daemon ~/core

发电平台是ARM版本，这GDB-multiarch声称支持，按照集架构名单。

The generating platform is armv4, which gdb-multiarch claim to support, according to the "set architecture" list.

编辑：为了澄清，我正在运行GDB的台式机是x86_64的Linux的GNU的，即一个64位的Ubuntu英特尔箱

To clarify, my desktop machine running gdb is "x86_64-linux-gnu", namely an 64-bit Intel Ubuntu box.

推荐答案
