problem

we have a problem installing protobuf to make

CDPATH="${ZSH_VERSION+.}:" && cd . && /bin/bash /home/user/protobuf-2.6.1/protobuf-2.6.1/missing aclocal-1.14 -I m4
/home/user/protobuf-2.6.1/protobuf-2.6.1/missing: line 81: aclocal-1.14: command not found
WARNING: 'aclocal-1.14' is missing on your system.
         You should only need it if you modified 'acinclude.m4' or
         'configure.ac' or m4 files included by 'configure.ac'.
         The 'aclocal' program is part of the GNU Automake package:
         <http://www.gnu.org/software/automake>
         It also requires GNU Autoconf, GNU m4 and Perl in order to run:
         <http://www.gnu.org/software/autoconf>
         <http://www.gnu.org/software/m4/>
         <http://www.perl.org/>
Makefile:641: recipe for target 'aclocal.m4' failed
make: *** [aclocal.m4] Error 127

solution

actually I used only one instruction
sudo autoreconf-ivf
