linux - 让 gdb 自动读取 ./.gdbinit

Question

使用原始 gdb (Debian 8.2.1-2) 调试 RefPerSys(GPLv3+，在 gitlab 上)提交 ec4ab756d302056cace0b在我的 Linux/x86-64/Debian Sid AMD2970WX 桌面上，我重现了

rimski.x86_64 ~/refpersys 14:39 .0 % gdb --args ./refpersys --object-tinybenchmark1

For more information about this security protection see the
"Auto-loading safe path" section in the GDB manual.  E.g., run from the shell:
    info "(gdb)Auto-loading safe path"

拥有我的 ./.gdbinit 有什么魔力？在没有诊断的情况下被这样的 gdb 调用消化了吗？ .gdbinit 包含:

# file refpersys/.gdbinit 
# GPLv3+ licensed 
add-auto-load-safe-path ./.gdbinit 
break abort 
break rps_fatal_stop_at 
set max-value-size 67108864

我可以(过去也这样做过)从其源代码重建 gdb。但今天，我很蹩脚，更喜欢专注于我的错误。

正如启动 gdb 时警告所说:

To enable execution of this file add
    add-auto-load-safe-path /home/basile/refpersys/.gdbinit
line to your configuration file "/home/basile/.gdbinit".

您似乎误解了该行并将其添加到您的存储库中的 .gdbinit 文件中，但它需要进入您的主目录。

如果 .gdbinit 文件在您的主目录中尚不存在，您可以创建它并仅在上面添加所需的行，它应该可以工作。
