Macos Mojave上的GDB错误

Question

环境：Mac/Mojave和GDB 8.2.1（通过Homebrew）。

我通过说明进行了https://forward-in-code.blogspot.com/2018/11/mojave-vs-gdb.html i。：

• 最新的GDB通过brew，它解决了可执行格式的问题

• 带有新权利的签名GDB

此外，我还修改了SIP以允许调试（在恢复OS终端：csrutil enable --without debug）。

但是，我仍然无法让GDB工作：

(gdb) file main
Reading symbols from main...done.
(gdb) run
Starting program: /Users/joubertold/code/Rhodus/obj/debug/main 
[New Thread 0x1a03 of process 5082]
[New Thread 0x2803 of process 5082]
During startup program terminated with signal ?, Unknown signal.
(gdb) 

有趣的是，LLDB在同一二进制中为我工作：

(lldb) file main
Current executable set to 'main' (x86_64).
(lldb) run
Process 5086 launched: '/Users/joubertold/code/Rhodus/obj/debug/main' (x86_64)
Rhodus
 1 is ONE
 1 is between 1 and 10
 1 is between 1 and 10
 1 is between 1 and 10
 1 is between 1 and 10
 1 is between 1 and 10
 1 is between 1 and 10
 1 is between 1 and 10
 1 is between 1 and 10
 1 is beyond
 1 is beyond
 1 is beyond
Process 5086 exited with status = 0 (0x00000000) 
(lldb) 

有什么想法吗？

Answer 1

我让GDB在莫哈维（Mojave）上工作：

a）获取最新的GDB源存档（在写作时，ftp://sourceware.org/pub/gdb/snapshots/current/current/gdb-weekly-8.2.50.20190212.tar.xz）它添加了用于识别Mac上可执行文件的处理。

b）构建GDB。我在darwin-nat.c中遇到了可变阴影的错误，所以我编辑了文件并重建（diff https://gist.github.com/joubertnel/267CA0FFF4EAAD494CC19EC3BA7953ED）。

）。

c）在https://forward-in-code.blogspot.com/2018/11/mojave-vs-gdb.html

中遵循步骤

瞧。

不幸的是，接受的答案对我不起作用。

对于与我同样情况下的任何人，我建议使用Visual Studio代码或Xcode来调试您的C程序。
