ok it works thanks but! i have no accepted shares so far ? hashrate is showing up to me but not on pool..

edit: says GPU_USE_SYNC_OBJECTS is not specified?
edit2: is it possible to mine 2 algo with one card?
ah lol you're doing a beginners mistake, you have to set the environment variables before you start the miners, otherwise you only get HW Errors.
do:
export GPU_MAX_ALLOC_PERCENT=100
export GPU_USE_SYNC_OBJECTS=1
BEFORE you start ./sgminer ....
