Does anybody know what I need to add to my configure.ac to get C++11 (or C++0x) support added to the gcc flags at compile time?

I've tried using:

   AC_LANG([C++])
   AC_PROG_CXX
   AX_CXX_COMPILE_STDCXX_11([noext])

But that fails at configure time.

Care for posting how exactly that fails?

Besides AX_CXX_COMPILE_STDCXX_11 is part of autoconf-archive. Adding autoconf-
archive to DEPENDS might help. You could also dump the macro directly into say 
m4 dir in your source package and add EXTRA_AUTORECONF_append = "-I${S}/m4" 
the recipe.

Ah - I meant to say "with a syntax error" !

Thanks, I'll have a look at that. In the mean time I've added CFLAGS+=" -std=c++x0" to get me going.
