I am trying to recompile the driver included in Red Hat 7.0 ( kernel 2.2.16
)
Please look at the outputs and help me understand what is going on in this
release.
Driver version:
static const char *version =
"eepro100.c:v1.09j-t 9/29/99 Donald Becker
http://cesdis.gsfc.nasa.gov/linux/dri
vers/eepro100.html\n"
"eepro100.c: $Revision: 1.20.2.10 $ 2000/05/31 Modified by Andrey V.
Savochkin <
saw@saw.sw.com.sg> and others\n";
I get the following errors:
