File format not recognized error while installing CBLAS on a Ubuntu machine

Question

I need to install CBLAS on an Ubuntu 16.04.4 machine. The following values have been set in the Makefile.in file of CBLAS:

SHELL = /bin/sh

PLAT = LINUX

BLLIB = /home/ubuntu/BLAS-3.8.0/blas_LINUX.a
CBLIB = /home/ubuntu/CBLAS/lib/cblas_LINUX.a

CC = gcc
FC = gfortran
LOADER = $(FC)

CFLAGS = -O3 -DADD_ -fPIC
FFLAGS = -O3 -fPIC

ARCH = gcc
ARCHFLAGS = -shared -o
RANLIB = ranlib

However, while running the make command I run into following error:

ranlib: /home/ubuntu/CBLAS/lib/cblas_LINUX.a: File format not recognized

The following is the stack trace:

Can someone suggest how this can be resolved?
