Trouble Compiling - Mandrake 6.1

[Torrey Peacock]

I've been having a very hard time compiling tulip.  My computer is a dual 
boot setup with Windows 98 and Linux Mandrake 6.1.  I have the @home cable 
Internet service, and a SOHOware NDC 10/100 Fast Ethernet PCI card.  The 
card includes a tulip driver for Linux on the install disk, but neither 
that version, nor any of the others I have found on the Net will 
compile.  I have used many different command lines, including exact copies 
from the tulip source code. and from various Web pages and How-To's.

The main error message I get is:
tulip.c :101: warning : *warning You must compile this file with the 
correct options!
tulip.c :102 : warning : *warning See the last lines of the source file.
tulip.c :103 : warning : *warning You must compile this driver with "-O".

Depending on what arguments I put on the command line, I will also get an 
error message from gcc saying that "-O is an unrecognized 
option."  (!!)  I'm not a complete newbie to Linux, but I don't know very 
much about the technical side.  I finally learned how to set-up a PPP 
dial-up connection in Linux, but this Ethernet thing is driving me 
crazy.  eth0 is not a "known device" to the kernel, so I assume I have to 
add tulip as a module, or recompile the kernel with it.

Can anybody help?  By the way, I have tried -O option with both O (upper 
and lower case letter) and 0 (numeral zero).

Thanks,
Torrey
