cgminer use only cpu

How can I force cgminer to use only the CPU? because I am getting the following error:
"Error: Getting Device IDS <num>"
clDevicesNum returned error
I am using the following args: cgminer -o server:port -u username -p password -t 1 -g 0

The -g flag set the number of gpu threads.
For just my i7 I would use.
cgminer -o
http://127.0.0.1:8337
-u gpu1 -p x -a 4way -t 7 -g 0
edit - I see you already set -g. Try either -a 4way or -a c

Solution:
The reason that it doesnt work for you is that you have the APP SDK installed (it compiles for GPU) but you dont have a supported GPU card.
So either remove the APP SDK and/or edit the configure file:
Around line 7925 change the following
****** OLD *********
$as_echo "#define HAVE_OPENCL 1" >>confdefs.h
found_opencl=1
OPENCL_LIBS=$OPENCL_FLAGS
****** NEW *****
found_opencl=0
****************
This basically just turns off GPU support when its time to compile.
It worked for me.
Would have posted it in the cgminer thread if i would have been allowed to do so since someone asked there too.
