aureal soundcard problem

[klax33]

i've been trying to setup my aureal based soundcard on my fresh rh7.1 install with no success. it worked fine in 6.2, i just ran the driver files and they played. now they are giving me these errors i don't know what do with, so if you do, please help me out. i can't code without music! i've tried all versions of the drivers and this is the error message i receive:

[root@localhost aureal]# make install
