在Ubuntu 16.04上,我成功地通过以下步骤在Python 3.5中获取了Python堆栈跟踪:
1. 安装`python3-dbg`和`python3-dev`:
```
$ sudo apt install python3-dbg python3-dev
```
`python3-dbg`软件包附带了如何在`/usr/share/doc/python3-dbg/README.debug`中使用它的简短文档,我将在下一步中使用它。
2. 将解压缩的GDB助手脚本`/usr/share/doc/python3.5/gdbinit.gz`追加到`~/.gdbinit`文件中:
```
zcat /usr/share/doc/python3.5/gdbinit.gz >> ~/.gdbinit
```
现在,gdb将能够找到Python二进制文件的符号,并且`py-bt`命令可以在gdb中显示Python堆栈跟踪。
