i start to learn debugging python code using gdb. But when i add breakpoint, gdb give error:"No source file named test.py."

this is my source code test.py:

a = "foo"
b = "bar"

c = a + b
print c

this is my gdb debug information：

done.

Make breakpoint pending on future shared library load? (y or [n])

  • i have used the command " gdb --args python pan.py", but when i add breakpoint, it still not work, give the same error. – PZY Oct 11 '17 at 09:09
  • Why you use gdb for debugging a python script ? just if you want to debug the python binary it make sense – invictus1306 Oct 11 '17 at 09:16
  • in any case try to look at this https://wiki.python.org/moin/DebuggingWithGdb – invictus1306 Oct 11 '17 at 09:18
  • @invictus1306，recently, i need to debug python code extended by c language code, pdb can just debug python code, but i need to debug the c code part. so i write python snippets using gdb debugging. – PZY Oct 11 '17 at 09:25
  • Understand now :) look at this https://stackoverflow.com/questions/7412708/debugging-stepping-through-python-script-using-gdb – invictus1306 Oct 11 '17 at 09:36
  • @invictus1306， i have read that, but i still don't know how to step debug the code. – PZY Oct 11 '17 at 10:15

    You can run `gdb --args python -mpdb pan.py`, then `run` the python interpreter and use pdb to debug at the python level. After your compiled C code is loaded, type Ctrl-C to get back to gdb and set breakpoints etc. – Mark Plotnick Oct 11 '17 at 22:38
  • @MarkPlotnick，right，thank you very much. – PZY Oct 12 '17 at 01:55
