5 years ago Our gdb doesn't include the embedded python interpreter. I just use a recent system gdb instead. If you wanted to, a standalone GDB package with python integration would be useful. Maybe conda-forge would accept such a package?

Thanks for the reply Ray. Really I don't want to debug python code so I don't need the python integration. Just looking to debug C++ extensions. Can't seem to get past the "Don't know how to run. Try "help target". I thought gdb would run python as C code and stop in any C++ python extension errors, is python integration necessary for that?

5 years ago Yes it is.

5 years ago You can run also python and stick an infinite loop in your extension module then connect to python's PID with gdb.

5 years ago I ran into a similar problem with the gdb_linux-64 package. Trying to attach to an already running process, I get a Don't know how to attach error:

Don't know how to attach. Try "help target".The conda-forge gdb package works just fine though.
Edit: There is an issue with ncurses that affects many package including gdb:
The defaults ncurses doesn't have the versioned libtinfo.so.6 (it only has libtinfo.so)

Actual Behavior
I'm trying to debug a C++ python extension that was built using the new Anaconda compilers. Note I'm not trying to debug the python .py code, nor the C python code, just the C/C++ extensions we developed. The gdb package gdb_linux-64 was also installed to the environment. When running gdb I get the following:
$ x86_64-conda_cos6-linux-gnu-gdb python GNU gdb (crosstool-NG fa8859cb) 7.12.1 Copyright (C) 2017 Free Software Foundation, Inc.

Reading symbols from python...done. (gdb) run gdb_test.py Don't know how to run. Try "help target".
This same approach of running gdb and python works fine for the system python. It's probably something simple, however, after much web searching and looking at other issues, I could not find much help on how to run the Anaconda gdb in an environment. I tried "help target", but it's not very clear what to do. Perhaps ~/.gdbinit needs something added, currently I don't have one.
Any guidance on how to get gdb working would be most appreciated.
Expected Behavior
The gdb program runs the test script.
