I want to debug with CodeLLDB on CentOS 7, but get an error like this:
/home/xxx/.vscode/extensions/vadimcn.vscode-lldb-1.6.1/adapter/codelldb: /lib64/libc.so.6: version `GLIBC_2.18' not found (required by /home/xxx/.vscode/extensions/vadimcn.vscode-lldb-1.6.1/adapter/codelldb)
LLDB requires a higher version of glibc.
I get it work by the following steps:
| #!/usr/bin/env python | |
| import sys | |
| import os | |
| import json | |
| cmd = ''' | |
| ceph pg dump | awk ' /^pg_stat/ { col=1; while($col!="up") {col++}; col++ } /^[0-9a-f]+\.[0-9a-f]+/ {print $1,$col}' | |
| ''' | |
| body = os.popen(cmd).read() | |
| SUM = {} | |
| for line in body.split('\n'): |
