Symbol not defined when using gdb to debug the kernel.

[pppkkkuuu]

I boot the kernel successfully by running make boot, and I run make gdb to connect to the VM. But when I want to set a break point, e.g., break sys_access, break sys_dup2. It says that:

When I launched the gdb, it say my gdb is configured for x86_64-linux-gnu, and here is the output when I run show configuration in gdb. I doubt may be I should change the target of my gdb to x86 instead?

I have same problem. Did you find a solution to the problem?

[pppkkkuuu]

Not yet.

Not yet.

Branch so_2020 work well for me. But it base kernel 4.19.

I checked the symbols defined inside the vmlinux file and all the syscalls are preceded by __ia32_, so sys_access becomes __ia32_sys_access.
