[Numpy-discussion] Help needed GDB

[Amardeep Singh]

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




https://github.com/crosstool-ng/crosstool-ng/issues/1308


 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())
