That is what I am doing for other C++11 features in my projects (see https://github.com/rhdunn/cainteoir-engine/blob/master/m4/cxx11.m4). For example: AC_DEFUN([CXX11_AUTO], [ AC_LANG_PUSH(C++) AC_MSG_CHECKING([if $CXX supports C++11 auto]) AC_COMPILE_IFELSE( [AC_LANG_PROGRAM( [[]], [[class A {} a;] [auto b = a;]])], [AC_MSG_RESULT([yes])], [AC_MSG_RESULT([no]) AC_MSG_ERROR([C++11 auto not supported by $CXX.])]) AC_LANG_POP(C++)]) Feel free to use & improve. - Reece _______________________________________________ gtkmm-list mailing list [email protected] https://mail.gnome.org/mailman/listinfo/gtkmm-list
