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.
source F:\msys64\mingw64\etc\gdbinit
I see that I have to modify the file "F:\msys64\mingw64\etc\gdbinit" file: below is the original 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
But you have to add one line before the "end" statement like below to let the register_libstdcxx_printers function get executed.
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
BTW: It is the same thing to add the python pretty printer for wxWidgets. You can use this file:
