python - gdb 无法在 Mac Sierra 中正确安装

Question

我尝试了所有能找到的关于安装 gdb 的方法，但仍然无法使其工作。

以下是我安装和运行 gdb 的方法:

1. 使用 brew install gdb 安装 gdb

2. 然后它告诉我执行以下操作

   (experiment3.5) ->brew 安装 gdb 正在更新自制程序... ==>正在下载https://homebrew.bintray.com/bottles/gdb- 8.0.1.sierra.bottle.tar 已下载:/Users/Natsume/Library/Caches/Homebrew/gdb- 8.0.1.sierra.bottle.tar.gz ==>浇注gdb-8.0.1.sierra.bottle.tar.gz ==> 注意事项 gdb 需要特殊权限才能访问 Mach 端口。 您需要对二进制文件进行协同设计。有关说明，请参阅:
   https://sourceware.org/gdb/wiki/BuildingOnDarwin

   在 10.12 (Sierra) 或更高版本上使用 SIP，您需要运行以下命令:

   echo "set startup-with-shell off" >> ~/.gdbinit

3. 我确实完成了这两步。我按照确切的指令 here 完成了协同设计任务

4. 一切都很顺利。但是，当我运行以下代码时，我仍然收到相同的错误消息

我跑了gdb python test.py并收到以下消息

(experiment3.5)  ->gdb python signal_test.py

Python Exception <type 'exceptions.ImportError'> No module named libpython:
"/Users/Natsume/Documents/shendusuipian/pytorch/raw_pytorch/60min_intro/signal_test.py" is not a core dump: File format not recognized

然后我确实下载了libpython.py ，但我不知道该怎么办。

我没有这样的文件夹/Users/travis/miniconda3/conda-bld/python_1494603145199/work/Python-3.5.3/Programs/python.o'如上面警告消息中所述

更新我试图关注the steps here ，我直接用了gdb8.01.tar.gz通过brew install gdb下载，但我在下面收到错误消息。

Focus on one: /Users/Natsume/Desktop/src/gdb/8.0.1
 ->./configure --prefix=$HOME/opt/usr/local
-bash: ./configure: No such file or directory
Focus on one: /Users/Natsume/Desktop/src/gdb/8.0.1

更新我从上面的链接运行了代码，并安装、配置了 gdb8.0，但是，我没有 $HOME/opt/usr/local 这样的文件夹。 ，但只有/opt/usr/local 。因此，虽然./configure --prefix=$HOME/opt/usr/local跑过去了，还是跑不了codesign -f -s "gdb-cert" <gnat_install_prefix>/bin/gdb ，因为没有 $HOME/opt/usr/local .

更新

正是按照上面的链接，我可以安装 gdb 8.0 ，但我无法运行gfortran ,

(experiment3.5)  ->gfortran
-bash: gfortran: command not found

我也不能运行gdb python test.py成功:

(experiment3.5)  ->gdb --args python signal_test.py

更新通过this link build ~/.gdbinit可以摆脱 No module named libpython 的错误已解决；但是，警告或更大的问题仍然存在

Answer 1

我在这个问题上花了相当多的时间。您需要从源代码编译它。

看这里:

Running GDB in macOS sierra

这对我有用；)

请注意一点，请确保对其进行代码签名!注释可以在这里找到:Codesigning the Debugger

更新:

有关 Python 的内容，请看这里

http://unconj.ca/blog/setting-up-gdb-for-debugging-python-on-os-x.html

对于 gdb 本身

按照以下方式测试应该足够了

// simple.c
#include <stdio.h>

int main() {
  printf("Hello\n");
  return 0;
}

然后

# assuming that gdb is signed
cc -g -o simple simple.c
gdb ./simple

更新 - 系统完整性保护

当涉及到某些区域(例如/usr/bin)时，由于系统完整性保护处于打开状态，您将无法访问那里。您需要将其关闭:

# You need to boot to Recovery OS in a first place (before you call csrutil)
> csrutil disable

# you can also use another location as output
> lipo /usr/bin/python -thin x86_64 -output ~/python64
