Hi All

I was able to fix.

>import sys

>print(sys.version_info)

>end

sys.version_info(major=3, minor=9, micro=1, releaselevel='final', serial=0)

(gdb) quit

 this was the issue.


The solution is to open /gdb/python/python-config.py and comment out these two lines:

 if getvar('LINKFORSHARED') is not None:
  libs.extend(getvar('LINKFORSHARED').split())

Hi All,

I am trying to debug c code of numpy via gdb.Can someone help me with this?
i am getting " Python scripting is not supported in this copy of GDB". How to install python supported gdb on win10?



I am following the steps in the docs. machine is windows 10.

Debugging

Another frequently asked question is “How do I debug C code inside NumPy?”. First, ensure that you have gdb installed on your system with the Python extensions (often the default on Linux). You can see which version of Python is running inside gdb to verify your setup:

(gdb) python
>import sys
>print(sys.version_info)
>end
sys.version_info(major=3, minor=7, micro=0, releaselevel='final', serial=0)



$ gdb -v
GNU gdb (GDB) 7.6.1
This GDB was configured as "mingw32".

$ gdb
(gdb) python
>import sys
>print(sys.version_info)
>end
(gdb) Python scripting is not supported in this copy of GDB.
