Learning computer room can be old, are xp system. After you install the DEV C ++ found to MinGW64.
And I used to compile the debug command:
g++ -g *.cpp -o a
gdb a
Compile the program can not be debugged.
Always thought, simply can not debug, but recently I discovered the above command you can change it a little debugging.
g++ -g *.cpp -o a -m32
gdb32 a
