gdb无法正确安装在Mac中

Question

我试过了我能找到的关于安装gdb的所有东西，但仍然无法使它工作。

下面是我如何安装和运行gdb：

1. 用brew install gdb安装gdb
2. 然后它告诉我执行以下操作 (实验3.5) ->brew安装gdb更新==>下载https://homebrew.bintray.com/bottles/gdb- 8.0.1.sierra.bottle.tar已经下载:/Users/https://homebrew.bintray.com/bottles/gdb-/8.0.1.sierra.bottle.tar/Caches/Homebrew/GDB-2/GDB-GDB-8.0.1.sierra.ptainle.tar.gz ==>警告gdb需要特殊权限才能访问Mach端口。您将需要协同设计二进制文件。关于指示，见： https://sourceware.org/gdb/wiki/BuildingOnDarwin 在10.12 (塞拉利昂)或更高版本的SIP中，您需要运行以下命令： echo "set startup-with-shell off" >> ~/.gdbinit
3. 我完成了这两步。我按照这里的精确指令完成了codesign任务
4. 一切进展顺利。但是，当我运行以下代码时，仍然会收到相同的错误消息

我运行了gdb python test.py并收到了以下消息

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

1. 然后我下载了libpython.py，但我不知道该如何处理它。
2. 我没有上述警告信息中所述的/Users/travis/miniconda3/conda-bld/python_1494603145199/work/Python-3.5.3/Programs/python.o'文件夹

Update我尝试遵循这里的台阶，我直接使用了通过brew install gdb下载的gdb8.01.tar.gz，但是我在下面得到了错误消息。

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

update --我从上面的链接中运行了代码，并安装、配置了gdb8.0，但是，我没有$HOME/opt/usr/local文件夹，而只有/opt/usr/local。因此，虽然./configure --prefix=$HOME/opt/usr/local运行过，但我仍然不能运行codesign -f -s "gdb-cert" <gnat_install_prefix>/bin/gdb，因为没有$HOME/opt/usr/local。

更新

对于上面的链接，我可以安装gdb 8.0，但不能运行gfortran，

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

我也不能成功地运行gdb python test.py：

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

通过此链接更新来构建~/.gdbinit可以消除No module named libpython的错误，但是仍然存在警告或更大的问题。

Answer 1

我在这件事上花了不少时间。您需要从源代码编译它。

请看这里：

在macOS塞拉利昂运行GDB

它对我起作用;)

只要一张便条，一定要在密码上签名！注意事项可以在这里找到：调试器的协同设计

更新：

有关python的内容，请看这里的

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

对于gdb本身

它应该足够用下面的方式测试它。

// 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，您将无法访问那里，因为系统完整性保护是开着的。你需要关掉它：

# 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
