GDB: ImportError: No module named libstdcxx.v6.printers

Question

I have MSYS2 and MinGW64 installed under Windows 7.

gdb reports "ImportError: No module named libstdcxx.v6.printers":

ImportError: No module named libstdcxx.v6.printers  
/etc/gdbinit:6: Error in sourced command file:  
Error while executing Python code.  
(gdb) quit  

I have found several links:

Import Error: No module name libstdcxx

ImportError: No module named 'libstdcxx' while debuging project with ncurses

How to enable gdb pretty printing for C++ STL objects in Eclipse CDT?

https://github.com/Alexpux/MINGW-packages/issues/383

but none of them helps.

Update:

There are 2 gdbinit.

C:\Appl\msys64\etc\gdbinit:

python
import sys
sys.path.insert(0, sys.path[0] + '/../../gcc-6.3.0/python')
from libstdcxx.v6.printers import register_libstdcxx_printers
register_libstdcxx_printers (None)
end

C:\Appl\msys64\mingw64\etc\gdbinit:

python
import sys
sys.path.insert(0, sys.path[0] + 'C:/Appl/msys64/mingw64/share/gcc-7.1.0/python')
from libstdcxx.v6.printers import register_libstdcxx_printers
end

Thanks for KonstantinL's answer I also encountered this problem and solved it

my gcc version is 11.1 ，There is only one gdbinit at etc/gdbinit

And I found the libstdcxx library at /usr/share/gcc-11.3.0/python

Refer to KonstantinL's answer

Modify the gdbinit as “sys.path.insert(0, '/usr/share/gcc-11.3.0/python')”

GDB can run normally

Thanks for KonstantinL's answer
