任何人都知道C ++的良好免费调试器吗？

Question

I've been having a really hard time with those kinds of bugs that just don't make any sense, and an even bigger one with trying to figure out how Code::Blocks' debugger works. If there's any way to make it show pointers' contents, or to be able to switch between scopes' variables, then my problems would be solved already, though alternatives are always welcome.

Help me out guys, scattering couts through the entire code is the most counter-intuitive and insanity-inducing burden ever. D|

g ++ http://gcc.gnu.org/ “ GNU编译器集合包括C，C ++，Objective-C，Fortran，Java，Ada和Go的前端，以及这些语言的库（libstdc ++，libgcj。 ..）。GCC最初是作为GNU操作系统的编译器编写的。GNU系统开发为100％免费的软件，在尊重用户自由的意义上说是免费的。”

Answer 3

If there's any way to make it show pointers' contents

Yes. In Code::Blocks in you should be able to right-click and pointer in the Watches list and select 'Dereference pointer'. If the pointer is a member of an object, you may have to add it manually by right-clicking in the Watches list and and typing the full reference to the member.

// Type 'pA->int1' in the 'Add watch' and code::blocks should add it. 
class A {
  public:
    int int1;
};

int main()
{
  A * pA = new A;
}

To add to other answers (obviously GDB...), LLDB is BSD-style licensed which is more permissive. It is part of the LLVM Compiler Infrastructure . is very similar to GDB (see a comparison ).
