使用mingw调试stl容器,python脚本出现问题

好的,我不会放弃.
我试图在代码块中进行设置,但是效果也不佳：

所以看起来这与日食无关,但脚本行为异常.
编辑：
我刚刚启动了msys,导航到了eclipse可能执行的相同路径(2-environment-cd D：/ work / ludum-dare / Debug),设置了相同的参数(5-enable-pretty-printing除外,因为gdb-python没有似乎知道该设置)并最终获取.gdbinit.完全没有错误.
有谁知道如何在我单击“调试”时找出正在尝试运行的Eclipse？
我还尝试了“标准创建过程启动器”,起初运行很顺利,但是在跟踪控制台中向上滚动时,我看到它只是跳过了python文件中遇到的错误.
编辑：我只是意识到不设置5-enable-pretty-printing不会在printers.py中设置_use_gdb_pp,因此无论如何它都不会以与eclipse中相同的方式运行.
我想mingw eclipse cdt中的漂亮打印坏了
在执行以下步骤之后：https://stackoverflow.com/a/14266862/3239702
我在Eclipse中面临以下输出：

我在网上搜索了其他有此问题的人,但看起来我中奖了.我有：
面向C/C++开发人员的Eclipse IDE
版本：开普勒服务版本1
Build ID：20130919-0819
我的mingw安装程序已全部更新,并且从以下位置安装了gdb-python27：
gdb-python-7.5.1-mingw32-bin.tar.lzma
python 2.7.6 32位
用户环境变量：
PYTHONHOME = C:\Python27
PYTHONPATH = C:\Python27\Lib
PATH = c:\mingw\bin
全局环境变量：
包含更多内容,我只发布相关部分：
PATH = C:\Python27\;
编辑：
我只是尝试了svn(svn：//gcc.gnu.org/svn/gcc/trunk/libstdc -v3 / python)中的python脚本,因此我相应地更改了.gdbinit中的路径.
“ gdb traces”控制台中的输出几乎相同,除了几行不同,但这些行中的错误是相同的,所以我认为只是进行了一些重构或类似的操作.
还有我的.gdbinit文件.在svn结帐之前,使用注释行而不是第4行：
python
import sys
# sys.path.insert(0, 'C:/MinGW/share/gcc-4.8.1/python')
sys.path.insert(0, 'D:/work/libstdc++-v3/python')
from libstdcxx.v6.printers import register_libstdcxx_printers
register_libstdcxx_printers (None)
end
编辑：
尝试调试printers.py脚本：
我向register_libstdcxx_printers函数添加了一些打印：
def register_libstdcxx_printers (obj):
"Register libstdc++ pretty-printers with objfile Obj."
global _use_gdb_pp
global libstdcxx_printer
print("initialy obj: " + str(obj))
print("_use_gdb_pp: " + str(_use_gdb_pp))
if _use_gdb_pp:
gdb.printing.register_pretty_printer(obj, libstdcxx_printer)
else:
if obj is None:
obj = gdb
obj.pretty_printers.append(libstdcxx_printer)
print("after gdb.printing.register_pretty_printer(obj, libstdcxx_printer): obj: " + str(obj))
register_type_printers(obj)
输出是：
559,740 ~"initialy obj: None\n"
559,740 ~"_use_gdb_pp: True\n"
559,740 ~"after gdb.printing.register_pretty_printer(obj, libstdcxx_printer): obj: None\n"
我真的不能怪它没有在None上找不到属性’type_printers’,现在可以吗？
我想没有来自我的.gdbinit的第6行：
register_libstdcxx_printers (None)
解决方法:
MinGW GDB 7.5.1使用标准GDB 7.6中的Python脚本.因此,脚本将失败.
在我将syscalls和python文件夹复制出来之后
http://ftp.gnu.org/gnu/gdb/gdb-7.5.1.tar.gz
并再次尝试了一切,奇迹般地奏效了.
Starting debugger: C:\MinGW\bin\gdb-python27.exe -nx -fullname -quiet

$2 = "'ces:getEntitiesWithComponent(\"position\")'"
因此,对将gdb 7.6 python脚本放入MinGW GDB 7.5.1程序包中的人来说,“工作很不错”.不.
