gdb以信号？，未知信号终止 [英] gdb terminated with signal ?, unknown signal

问题描述

我试图在Mac OSX V10.12上用gdb调试代码，但是在gdb启动我的程序时总是得到这个未知的错误。

我对gdb安装完成后，用-g标记编译我的代码。

这就是发生了什么：

 计算机：hello用户$ gdb a.out

完成。 
（gdb）r 
启动程序：/Users/user/Documents/Programming/hello/a.out 
启动程序在信号？，未知信号时终止。 
  

暂时我得到了SIGTRAP信号，但我无法弄清楚为什么现在再次抛出Unknown信号。

解决方案

适用于Mac OS X 10.12.5及更新版本的解决方案

在home-direcetory中创建一个.gdbinit文件，并在其中写入set startup-with-shell off。

文件可以使用 vi〜/ .gdbinit 。

创建。

打开一个新的终端并使用gdb。

I'm just trying to debug code with gdb on Mac OSX Version 10.12 but always getting this unknown error when launching my program in gdb.

I codesigned the gdb after installation and compiled my code with the -g flag.

This is what is happening:

done.
(gdb) r
Starting program: /Users/user/Documents/Programming/hello/a.out 
During startup program terminated with signal ?, Unknown signal.

Temporary I got the SIGTRAP signal, but I could not figure out why it's now throwing the Unknown signal again.

解决方案

Solution for Mac OS X 10.12.5 and newer

Create a .gdbinit file in your home-direcetory and write "set startup-with-shell off" in it.

File can be created using vi ~/.gdbinit.

Open a new terminal and gdb will work.
