gdb终止了信号？,未知信号

Question

我只是试图在Mac OSX版本10.12上使用gdb调试代码,但在gdb中启动程序时总是会收到此未知错误.

我在安装后对gdb进行了编码,并使用-g标志编译了我的代码.

这就是发生的事情:

computer:hello user$ gdb a.out

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

临时我得到了SIGTRAP信号,但我无法弄清楚为什么它现在再次抛出未知信号.

Answer 1

适用于Mac OS X 10.12.5及更高版本的解决方案

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

可以使用创建文件vi ~/.gdbinit.

打开一个新的终端,gdb将工作.

这是因为您使用的是最新版本的 OSX 10.12 或 10.12.1。降级或等待 OSX/GDB 修复似乎是最好的选择。我一整天都在忙着弄清楚这个问题。不要浪费时间尝试与 Sierra 一起解决这个问题！
