How to start GDB for C++ called from Python?

阅读更多关于 How to start GDB for C++ called from Python?

问题 I need to debug a C++ function that is called from Python code. How to start GDB (or better DDD) in such a way that it debugs the C++ code called from a given Python command line? The given Python command line is: python3 -m e2e.Tests.Libs.HundredEightyOneTest It calls a C++ code that I need to debug. 回答1: My recommendation: recompile your python interpreter from its source code (so it gets compiled with DWARF debug information, practically speaking with GCC invoked as gcc -Wall -O -g ). Once

GDB: How to list all source files used for compilation

阅读更多关于 GDB: How to list all source files used for compilation

问题 New to the project, have multiple source files used for compilation and some "could" be dynamic libraries, loaded at runtime. When debugging the executable using "GDB", is there a command to list all the source files (static) used to build the executable. Once I have all the source files, it's easy for me to set breakpoints, list functions etc. I couldn't find a command to do it in GDB (I'm sure there should be one). In DDD (gui based gdb), there is a Menu: File->List, which lists all the

问题 Is there a native (not cygwin) version of DDD available for download somewhere? 回答1: There is also a GDB front-end for MS Visual Studio, called WinGDB. It supports both Cygwin and MinGW. You use it just like built-in debugger in VS. It's also possible to debug remotely on Linux via SSH. 回答2: DDD has not been ported to Windows AFAIK. But there ARE native gdb, which can be perfectly built using MingW32. You can also build Insight natively using Mingw32. You can also give a try to BeaverDbg 回答3:

Starting ddd with remote gdbserver

问题 I'm debugging a program that runs on a remote target using ddd ( the remote gdbserver is running on localhost over port 1234 for example, but still acts as remote). I know you can connect to the gdbserver by opening ddd, then calling target remote localhost:1234 on the gdb command line of ddd, as described in: http://www.gnu.org/software/ddd/manual/html_mono/ddd.html#Remote%20Program However, I hate having to call the target remote localhost:1234 command every time I open ddd, and I'd like to

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed last month . I am developing c on linux using vim and debugging using ddd. However I find that ddd performs very poorly at scrolling on this machine so its sometimes very frustrating to use. I like the way that ddd maps fairly closely to the gdb command set as this means I am free to use gdb commands when I choose, but using

Debugging Python and C++ exposed by boost together

阅读更多关于 Debugging Python and C++ exposed by boost together

I can debug Python code using ddd -pydb prog.py . All the python command line arguments can be passed too after prog.py . In my case, many classes have been implemented in C++ that are exposed to python using boost-python . I wish I could debug python code and C++ together. For example I want to set break points like this : break my_python.py:123 break my_cpp.cpp:456 cont Of course I am trying it after compiling c++ codes with debug option but the debugger does not cross boost boundary. Is there any way? EDIT : I saw http://www.boost.org/doc/libs/1_61_0/libs/python/doc/html/faq/how_do_i_debug
