Thank you.
I configured this long time ago and don't know if there's better since this date, but here is what's in my C::B settings (Settings->Debugger->Init commands) in Windows (on Mac, I don't use the debugger from C::B):
Code: Select all
python
import sys
import gdb
sys.path.insert(0,'C:/MinGW64/bin/wxprint')
import wxprint
end
set print pretty 1
My default (the one in PATH) Python is 2.7 and here is the referenced wxprint.py script in my MinGW64 (aka. TDM-GCC 86_64) tree:
