When directly invoking gdb/gdbserver/configure && make, the build will fail because the $(host_alias) is empty and thus create-version.sh does not get enough parameters. The output of gdbserver --version without this patch (built like above): [...] This gdbserver was configured as "" After applying this patch: [...] This gdbserver was configured as "x86_64-unknown-linux-gnu" 2013-06-28 Mircea Gherzan <mircea.gherzan@intel.com> gdbserver: * configure.ac (version_host, version_target): Set and AC_SUBST them. * configure: Rebuild. * Makefile.in (version_host, version_target): Get from configure. (version.c): Use $(version_host) and $(version_target). Change-Id: Id48240532ad3d624ec78867a6db5ebd4c09583ff Signed-off-by: Mircea Gherzan <mircea.gherzan@intel.com>
