This is suggested by Jan but GDB is unable to find file1.txt, because GDB test harness doesn't set search directories for remote host, see gdb_reinitialize_dir in lib/gdb.exp: proc gdb_reinitialize_dir { subdir } { global gdb_prompt if [is_remote host] { return "" } so we have to set the search directory in the board file like set_board_info gdb_opts "-d \"${host_dir}\"" and copy file there without directory. diff --git a/gdb/testsuite/boards/local-remote-host-native.exp b/gdb/testsuite/boards/local-remote-host-native.exp new file mode 100644 index 0000000..b2a0b31 --- /dev/null +++ b/gdb/testsuite/boards/local-remote-host-native.exp @@ -0,0 +1,86 @@ +# Copyright 2014 Free Software Foundation, Inc. + +# This program is free software; you can redistribute it and/or modify +# it under the terms of the GNU General Public License as published by +# the Free Software Foundation; either version 3 of the License, or +# (at your option) any later version. +# +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
