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：

  • Why you use gdb for debugging a python script ? just if you want to debug the python binary it make sense Commented Oct 11, 2017 at 9:16

  • @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. Commented Oct 11, 2017 at 9:25

    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. Commented Oct 11, 2017 at 22:38
