Note: Because files will be copied to the .build-id directory of the system, root privileges are required every time you run ./download.
Upgrade GDB version (may be required)
If your environment is ubuntu16 or 18, then the default GDB version is lower (GDB < 8.3) and does not support parsing the symbol files in .build-id. In this case, you need to upgrade the GDB version.
Version 9.2 is recommended, use the following methods to complete the upgrade
apt install texinfo
cp `which gdb` `which gdb`-old
cp `which gdbserver` `which gdbserver`-old
wegt http://ftp.gnu.org/gnu/gdb/gdb-9.2.tar.gz
tar -xzvf gdb-9.2.tar.gz
cd gdb-9.2 && mkdir build && cd build
../configure --with-python=`which python3` --enable-targets=all
make && make install
