从eclipse中运行的python代码调试Visual Studio中的C ++代码

Question

Does any one know how we can do this? I have python code in eclipse and whenever it calls c++ functions, i want the break point to go to the visual studio c++ project.

Answer 1

You can use a __debugbreak in visual studio so that every time the code is invoked it triggers the debugger (you may want to search the function in MSDN).

Insert the instruction in the C++ function (or class method) you want to debug, eg

void foo()
{
  __debugbreak();
  [...]
}

at this point compile the library and run the python script, when library loads and the code is executed a messagebox appears telling if you want to attach the visual studio debugger.

It is the replacement of the old __asm { int 3 } .

Answer 2

If the C++ app runs as a separate process then its pretty easy. You can run the process yourself or attach visual studio to existing running process and put break points.

If C++ code is an embedded DLL/LIB then you can use python as debug/launch process. As soon as python will load the DLL/LIB into your python code visual studio will activate your break points.

Alternatively you can also add windows debugger launcher calls to your code. As soon as your code gets executed, you will see a dialog box asking if you want to attach a debugger.
