让gdb自动读取。/.gdbinit

Question

通过在我的Linux/x86-64/Debian Sid AMD2970WX桌面上调试RefPerSys时使用原始的gdb (Debian 8.2.1-2) (GPLv3+，在gitlab上)提交ec4ab756d302056cace0b，我可以重复地获得

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

warning: File "/home/basile/refpersys/.gdbinit" auto-loading has been declined by your `auto-load safe-path' set to "$debugdir:$datadir/auto-load".
To enable execution of this file add
    add-auto-load-safe-path /home/basile/refpersys/.gdbinit
line to your configuration file "/home/basile/.gdbinit".
To completely disable this security protection add
    set auto-load safe-path /

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"

在没有诊断的情况下，这样的gdb调用能够消化我的./.gdbinit，这有什么神奇之处呢？该.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(过去也是这么做的)从gdb的源代码重建它。但是今天，我变得无能为力，更喜欢专注于我的bug。

FWIW

正如启动gdb时出现的警告所示：

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，并将该行添加到您的存储库中的.gdbinit文件中，但它需要放到您的主目录中。

如果.gdbinit文件还不存在于您的主目录中，您可以创建它并只添加上面所需的行，它应该可以工作。
