# A helper script to analyze coredump files
|
# Usage: ./analyze_coredump.sh core-PID-NAME
|
# GDB require several infomations
|
# 1. The SYSROOT path for glibc/stdc++ and other library symbols
|
# 2. The solib-search-path, the script set it to current build outputs
|
# 3. The coredump files, can be pulled from device's /data/core-PID-NAME
|
# 4. make sure the demo and aiq library is matched to the ones running on device
