Debugger: use gdb python pretty printer for the libstdcxx under msys2

Hi, this is my way to use gdb python pretty printer for the libstdcxx under msys2.
Suppose you use 64bit gcc compiler. My msys2 is installed under F:\msys64

In the Menu->Settings->Debugger settings. Open the debugger plugin setting dialog.

Then, in the "Executable path" field, select "F:\msys64\mingw64\bin\gdb.exe"
in the "Debugger initialization commands" field, put the following text in the edit control.

--- Code: ---source F:\msys64\mingw64\etc\gdbinit

--- End code ---

I see that I have to modify the file "F:\msys64\mingw64\etc\gdbinit" file: below is the original code


--- Code: ---python
import sys
sys.path.insert(0, sys.path[0] + '/../../gcc-9.2.0/python')
from libstdcxx.v6.printers import register_libstdcxx_printers
end

--- End code ---

But you have to add one line before the "end" statement like below to let the register_libstdcxx_printers function get executed.


--- Code: ---python
import sys
sys.path.insert(0, sys.path[0] + '/../../gcc-9.2.0/python')
from libstdcxx.v6.printers import register_libstdcxx_printers
register_libstdcxx_printers(None)
end

--- End code ---

BTW: It is the same thing to add the python pretty printer for wxWidgets. You can use this file:

--- Code: ---https://github.com/wxWidgets/wxWidgets/blob/master/misc/gdb/print.py
--- End code ---

a wiki article would be nice :)

Done, see here: Configure GDB pretty printer for Msys2 - CodeBlocks

Though a bit late.

BlueHazzard:
Great!

Suryavarman:
It doesn't work for the wx print.
When i find some time i will use "source -p" like wxWidgets team say:


--- Quote ---this file is meant to
#               be sourced from gdb using "source -p" (or, better, autoloaded
#               in the future...)
