C compiler Problem Ubuntu [on hold]

Recently i was trying to install cpuminer and i ran this code to configure it

./configure CFLAGS="-03"

when this error came up

checking whether the C compiler works... no
configure: error: in `/home/default/cpuminer-master':
configure: error: C compiler cannot create executables

Now i did some googling and there are people with similar problems but with rdifferent logs. Mine consists of errors including invalid commandline options which is odd. Here is the log:

    This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by cpuminer configure 2.3.2, which was
generated by GNU Autoconf 2.69.  Invocation command line was

  $ ./configure CFLAGS=-03
