So as a newbie Linux user I have installed a Knoppix system on my computer (I'm using an AMD Athlon 1800+ XP processor). Everything works, but it can not find my network adapter (a RealTek RTL8139) card which is kind of irritating (which it can do when you run Knoppix from the CD). Anyway I have tried to compile the source code found on the web (there are two files I have tried: rtl8139.c and 8139too.c) When I try to compile them all I get is a lot of error messages that do not tell me anything really (since I'm a newbie).

I'm trying the following compile command:
gcc -DMODVERSIONS -DMODULE -D__KERNEL__ -Wall -Wstrict-prototypes -O6 -c rtl8139.c

To me that command line is mostly greek. Especially the "-DMODVERSIONS -DMODULE -D__KERNEL__ -Wall -Wstrict-prototypes -O6" line.

Can you type some sort of flag that makes the message that comes up after I type the command readable (like /p in old MS-DOS.)?

I get basically the same message when I try to compile run 8139too.c
