Build failure of OpenMPI due to _noalias when using mpicxx - c++

Question

I tried to install lammps on my department machine with a newer version of 11Aug17. However, mpicxx gives error to the following lines:
mpicxx -g -O3 -DLAMMPS_GZIP -DLAMMPS_MEMALIGN=64 -DMPICH_SKIP_MPICXX -DOMPI_SKIP_MPICXX=1 -I/home/shixx597/codes/kim-api-v1.7.3/lib/kim-api-v1/include -c ../pair_list.cpp

My colleagues told me that it is the problem of openmpi. So I tried to install a new openmpi for me. However, I get the following error told me that automake is not installed like this:
cd . && /bin/sh /home/shixx597/codes/openmpi-3.0.0/config/missing automake-1.15 --foreign
/home/shixx597/codes/openmpi-3.0.0/config/missing: line 81: automake-1.15: command not found
WARNING: 'automake-1.15' is missing on your system.
You should only need it if you modified 'Makefile.am' or
'configure.ac' or m4 files included by 'configure.ac'.
The 'automake' program is part of the GNU Automake package:

It also requires GNU Autoconf, GNU m4 and Perl in order to run:

When I tried to install automake-1.15, I get the following error:
CDPATH="${ZSH_VERSION+.}:" && cd . && "/home/shixx597/codes/automake-1.15/t/wrap/aclocal-1.15"

I do not have any sudo privilege to do anything on this weird department machine.
Even I tried to finish installing lammps on the departmental machine, I am wondering if I could finish the run of a large bonded force field model.

Actually, this a fairly well-known issue, and there are three solutions.
Use GCC rather than an Intel compiler (possibly not desirable).
Use the -restrict flag while compiling (I'm assuming by appending it when running make, like make CXX_FLAGS=-restrict
Just remove those two files from the build.
If you really want to try, you could also try to remove the _noalias keyword using sed or awk from the two offending files: pair_list.h and pair_list.cpp, or just define _noalias to be an empty keyword, as suggested by jww in the comments.
