AX_CXX_COMPILE_STDCXX_11 macro not found

Try to install Sigrok under Linux. Step: libsigrok installing. When I try ./autogen.sh I get a warning "AX_CXX_COMPILE_SRDCXX_11 macro not found".

How can it be - no macros in the autoconf-archive? I'm at a loss. As far as I see, it crashes my attempt to make PulseView package later (libsigrokxx>=0.3.0 not found).

I checked autoconf and autoconf-archive with Synaptic - it's ok, latest versions are installed. Don't know what to do next. No experience in building programs. Thanks!
