configure: error: C compiler cannot create executables
my system is ubuntu 14.04 and the system details say the os is 32 bit. any help would be great as the compiler fails on anytime I try to use it, not just with this install.
config.log output:
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 2.4.2, which was
generated by GNU Autoconf 2.69. Invocation command line was
$ ./configure CFLAGS=-03

My guess would be that you have the basic C compiler installed, but not the headers for the standard library. Try:
sudo apt install libc6-dev
[Edit: this produces similar symptoms, but wasn't the case here. The CFLAGS answers appear to be correct.]
From the config.log:
configure:3478: gcc -03 conftest.c >&5
gcc: error: unrecognized command line option '-03'
The option is -O3 with the letter O, not the number 0 (zero). So, you should run, as given in the README:
./configure CFLAGS="-O3"
Looks like your CFLAGS has a zero instead of capital O. That is invalid, and causing the compilation to fail. You can fix it, but really, look for a later version of the package which has been fixed.
I was having this exact same problem trying to install tivodecode on a base build of Linux Mint 17.3. I tried the:
./configure DFLAGS="-O3"
command but with no effect. So I tried:
sudo apt install libc6-dev
to install the latest C headers. I tried the ./configure command again with no variables and all went well. The make and make install commands also completed successfully. My recommendation is to make sure the latest C headers are installed and then run your ./configure command.
You can try to install build-essential
sudo apt-get install build-essential
