Hello,
The following macro makes use of `AC_CXX_COMPILER_VENDOR' which I posted
a few days ago [1] in order to determine what flags (compile-time)
should be passed to the C++ compiler to enable standard C++ support.
Other similar macros to follow.
dnl @synopsis AC_CXX_CXXFLAGS_STD_LANG(CXX-FLAGS)
dnl
dnl Append to variable CXX-FLAGS the set of compile-time flags that
dnl should be passed to the C++ compiler in order to enable use of
dnl C++ features as defined in the ANSI C++ standard (eg. use of
dnl standard iostream classes in the `std' namespace, etc.). Note that
dnl if you use GNU Libtool you may need to prefix each of those flags
dnl with `-Xcompiler' so that Libtool doesn't discard them (see
dnl Libtool's manual and `AC_LIBTOOLIZE_CFLAGS').
dnl
dnl @version 20040907
dnl @author Ludovic Courtès <address@hidden>
AC_DEFUN([AC_CXX_CXXFLAGS_STD_LANG],
[AC_REQUIRE([AC_CXX_COMPILER_VENDOR])
case "$ac_cv_cxx_compiler_vendor" in
sgi) $1="$$1 -LANG:std -exceptions";;
hp) $1="$$1 -AA";;
esac])
Thanks,
Ludovic.
