I am guessing your GDB is using python2 and not python3 |

Thanks, in the end, only use the parameter ‘--with-python=/usr/bin/python3.5’ to compile successfully and use it normally.
I also want to ask a question: How to upgrade the gdb version of gdb-multiarch? His gdb version is not consistent with the compiled gdb version

I am not sure how you are building your gdb, but I think you can just use |

Thank you. According to your suggestion, my problem is solved. You can debug the program of mips architecture without using gdb-multiarch.

I am not sure how you are building your gdb, but I think you can just use --enable-targets=all on your normal build.

Hello, I want to ask a question：
I want to use gdb to debug mips architecture programs, but the compiled gdb does not support stack, vmmap and other instructions. After using the gef plug-in, the vmmap instruction shows the following exceptions:
0x400868 <main+24> sw gp, 16(sp)
0x40086c <main+28> sw a0, 536(s8)
0x400870 <main+32> sw a1, 540(s8)
→ 0x400874 <main+36> lui v0, 0x40
0x400878 <main+40> lhu v0, 3084(v0)
0x40087c <main+44> sh v0, 24(s8)
0x400880 <main+48> addiu v0, s8, 26
0x400884 <main+52> li v1, 498
0x400888 <main+56> move a2, v1

Undefined command: "stack". Try "help".
The vmmap command cannot display libc, and the stack command cannot be used；What is going on?

A similar question just happened on me. I'm wondering how to let gdb use python3 interpret script instead of python2 on Ubuntu1604. |
