eclipse调试C++代码报错: Could not determine GDB version using command: gdb --version

Traceback (most recent call last):
  File "", line 3, in 
ImportError: No module named libstdcxx.v6.printers
d:\msyq64\mingw64\bin\../etc/gdbinit:5: Error in sourced command file:
Undefined command: "".  Try "help".
(gdb) q

按照报错提示，打开d:\msyq64\mingw64\bin\../etc/gdbinit看了下内容：

python
import sys
sys.path.insert(0, sys.path[0] + '/../../gcc-5.3.0/python')
from libstdcxx.v6.printers import register_libstdcxx_printers
register_libstdcxx_printers (None)
end

可疑的是里面有gcc版本号，于是我看了一下我当前gcc的版本号：

$ gcc -v
Using built-in specs.
COLLECT_GCC=D:\msys64\mingw64\bin\gcc.exe
COLLECT_LTO_WRAPPER=D:/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/6.1.0/lto-wrapper.exe
Target: x86_64-w64-mingw32

Thread model: posix
gcc version 6.1.0 (Rev1, Built by MSYS2 project)

发现并不是5.3.0，于是尝试将d:\msyq64\mingw64\bin\../etc/gdbinit中的gcc-5.3.0改成gcc-6.1.0，然后再将执行了一下gdb：

居然好了，特将此记录，供各位参考。
