如何从.gdbinit强制断点？ [英] How do I force a breakpoint from .gdbinit?

问题描述

当我使用以下方法在 .gdbinit 中设置断点时：

When I set a breakpoint in my .gdbinit using:

b foobar

我明白了：

Function "foobar" not defined.
Make breakpoint pending on future shared library load? (y or [n]) [answered N; input not from terminal]

现在第一行是可以理解的，因为该函数位于共享库中。但是，此默认设置为 no 。

Now the first line is understandable, because the function resides in a shared library. However, this defaults to no.

在这种非交互情况下，如何强制其设置断点？

How do I force it to set the breakpoint in such a non-interactive scenario?

推荐答案

这可以使用待设置的断点来完成。从设置断点文档：

gdb提供了一些附加命令来控制 break 命令无法将断点地址规范解析为地址时发生的情况：

gdb provides some additional commands for controlling what happens when the break command cannot resolve breakpoint address specification to an address:

设置断点等待自动-这是默认行为。当gdb找不到断点位置时，它会询问您是否应创建挂起的断点。


设置断点挂起-这表示无法识别的断点位置应自动导致创建挂起的断点。


设置断点挂起-这表明将不创建挂起断点。任何无法识别的断点位置都会导致错误。

set breakpoint pending auto - This is the default behavior. When gdb cannot find the breakpoint location, it queries you whether a pending breakpoint should be created.
set breakpoint pending on - This indicates that an unrecognized breakpoint location should automatically result in a pending breakpoint being created.
set breakpoint pending off - This indicates that pending breakpoints are not to be created. Any unrecognized breakpoint location results in an error.
