Re: gdbserver: Target description specified unknown architecture “aarch64”

[Peter Balazovic]

mine linux machine of gdb config

(gdb) show configuration
This GDB was configured as follows:
   configure --host=x86_64-linux-gnu --target=x86_64-linux-gnu
             --with-auto-load-dir=$debugdir:$datadir/auto-load
             --with-auto-load-safe-path=$debugdir:$datadir/auto-load
             --with-expat
             --with-gdb-datadir=/usr/share/gdb (relocatable)
             --with-jit-reader-dir=/usr/lib/gdb (relocatable)
             --without-libunwind-ia64
             --with-lzma
             --with-python=/usr (relocatable)
             --without-guile
             --with-separate-debug-dir=/usr/lib/debug (relocatable)
             --with-system-gdbinit=/etc/gdb/gdbinit
             --with-babeltrace

("Relocatable" means the directory can be moved with the GDB installation
tree, and GDB will still find it.)
(gdb) set architecture
auto               i386               i386:intel         i386:nacl
i386:x64-32        i386:x64-32:intel  i386:x64-32:nacl   i386:x86-64
i386:x86-64:intel  i386:x86-64:nacl   i8086
