debugging - gdbserver:目标描述指定的未知体系结构 "aarch64"

Question

我尝试如下远程使用gdbserver进行调试

在目标机器上启动gdbserver

$ gdbserver localhost:2000 hello -l 20 -b 10 --enable-targets=all

主机具有已启用调试的程序二进制文件

"copied binary from ARM target to host" 

在主机上运行gdb

$ gdb -q --args hello --enable-target=all

连接到目标

(gdb) target remote 192.168.15.132
192.168.15.132: No such file or directory.
(gdb) target remote 192.168.15.132:2000

here: 00000000;1f:80fcffffffff0000;20:403cfdb7ffff0000;thread:pd60.d60;core:1;
(gdb) q

我正在寻找正确调试ARM远程目标的建议。

要调试为其他体系结构编译的可执行文件，请安装gdb-multiarch并运行gdb-multiarch而不是gdb。不同的发行版对gdb的编译方式不同，有些甚至在其存储库中缺少multitarch版本-RHEL doesn't include it，但是它存在于Ubuntu和Debian中。
