Hi
I read the epic thread regarding installation of cgminer and cpuminer for ubuntu 12.04.
I am trying to install it in order to mine with a gridseed system.  After curl and jansson install fine, I keep getting error messages when attempting to build cpuminer from github.

When I get to -
CFLAGS="-02 -Wal -march=native" ./configure

I get:
configure: error: in '/home/x/usb-miner/software/cpuminer':
configure: error: C compiler cannot create executables

What am I doing wrong?
Please help me.  I think I am almost to the point of mining, but I'm stuck

Anything anyone can do would be greatly appreciated.
