'Running gdb on xv6-riscv-fall19

So I follow the commands on the website.

I open one windows and I used the command: sudo make qemu-gdb. And it asked me to use another terminal to start gdb.

When I used the gdb provided by the Linux system. It shows this error message:

.gdbinit:2: Error in sourced command file:
Undefined item: "riscv:rv64".

What should I do to fix the issue?

Solution 1:^[1]

You need to use riscv64-unknown-elf-gdb instead of gdb. It would be installed in your system when you install riscv-gnu-toolchain specified in xv6 site.

Solution 2:^[2]

use /usr/bin/gdb-multiarch instead

Solution 3:^[3]

Your gdb version should be 8.3 and later

Solution 4:^[4]

Replace all gdb with riscv64-unknown-elf-gdb when you are following the textbook and you should be good to go.

You can also run

riscv64-unknown-elf-gdb --version

to check the availability of this command. If something is not right, see this page to re-install the toolchain. (Remember to make clean before re-making to clean the temporary files.)

Solution 5:^[5]

riscv64-unknown-elf-gdb didn't come with the riscv-gnu-toolchain for me. Using gdb-multiarch in ubuntu 18 works for me.
