[gdb v10] My Build Cannot Tell the Symbol Info. to Debug the Core Dump

[SUN Michael <evcode@outlook.com>]

Hi team,


Now I meet an issue when to debug the core dump file. That’s it:
Using gdb v9 and the older version the related symbol files will be auto loaded following the command:
$ gdb $EXE $CORE -ex “set sysroot $SYMBOL_PATH”

GNU gdb (GDB) 9.2
Copyright (C) 2020 Free Software Foundation, Inc.
… …
Reading symbols from <$EXE>...
[New LWP 1800]
[New LWP  …  ]
… …
Reading symbols from XXX
… …
(gdb)


However, on gdb v10 there’s no “Reading symbols from” processing:(,
and the console directly goes to “(gdb)” without any wait or prompt.
And then after I typed “bt”, there’ no symbol information ― it seems the symbols have not been loaded at all:
#0  0x0000000c0d8b50 in ?? ()
#1  0x0000000ddbd808 in ?? ()


I CROSS-compiled v9 and v10 using the same configuration as below:
configure --host=x86_64-pc-linux-gnu --target=aarch64-linux-android --with-python=/usr/bin/python --with-expat --with-lzma

, and my v10’s “show configuration”:
   configure --host=x86_64-pc-linux-gnu --target=aarch64-linux-android
             --with-auto-load-dir=$debugdir:$datadir/auto-load
             --with-auto-load-safe-path=$debugdir:$datadir/auto-load
             --with-expat
             --with-gdb-datadir=/XXX/gdb/gdb-10/share/gdb (relocatable)
             --with-jit-reader-dir=/XXX/gdb/gdb-10/lib/gdb (relocatable)
             --without-libunwind-ia64
             --with-lzma
             --without-babeltrace
             --without-intel-pt
             --without-mpfr
             --without-xxhash
             --with-python=/usr
             --with-python-libdir=/usr/lib
             --without-debuginfod
             --without-guile
             --disable-source-highlight
             --with-separate-debug-dir=/XXX/gdb/gdb-10/lib/debug (relocatable)


Appreciate for your attention and help in advance:)
THX!!
