Bug ID: 58374
Summary: Wrong target check in configure.ac in libvtv
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: other
Assignee: unassigned at gcc dot gnu.org
Reporter: hjl.tools at gmail dot com
configure.ac in libvtv in has
unset VTV_SUPPORTED
AC_MSG_CHECKING([for host support for vtable verification])
. ${srcdir}/configure.tgt
AC_MSG_RESULT($VTV_SUPPORTED)
# Decide if it's usable.
use_vtable_verify=no
if test "x$VTV_SUPPORTED" = "xyes"; then
use_vtable_verify=yes
AC_MSG_NOTICE(using vtable verification)
fi
# Do not delete or change the following two lines. For why, see
# http://gcc.gnu.org/ml/libstdc++/2003-07/msg00451.html
AC_CANONICAL_SYSTEM
target_alias=${target_alias-$host_alias}
AC_SUBST(target_alias)
GCC_LIBSTDCXX_RAW_CXX_FLAGS
It won't work for targets like i686-linux nor x86_64-linux since
configure.tgt only recognizes canonical targets. The VTV_SUPPORTED
check should be moved after AC_CANONICAL_SYSTEM.
