#48 Making aureal driver work in Redhat 8.0
I spent the morning downloading, compiling, surfing,
fixing, etc, so I want to pass on my experiences re:
getting this driver to work in Redhat 8.0.
First off, make sure you get the *latest* sources from
CVS. If you've already tried building from the
downloads, be sure to remove the current driver, if
any, from /lib/modules/...
Second, create the /usr/src/linux link by typing "ln
/usr/src/linux-`uname -r` /usr/src/linux"
The driver should build fine, but insmod/modprobe will
complain that it was built with gcc2, though the kernel
was built with gcc3. Something like:
./au8830.o: The module you are trying to load
(./au8830.o) is
compiled with a gcc version 2 compiler, while the
kernel you
are running is compiled with a gcc version 3
compiler. This is
known to not work.
Note that part of this driver's distribution is a
binary file, asp*.o, and that it was built with gcc2.
Sigh. See http://aureal.sourceforge.net/ for an
explanation, suffice it to say that sources to asp*.o
aren't available, though a reverse-engineering effort
is underway.
For now, you have two options:
1) Force the module to load with insmod -f, probably in
rc.local or whereever.
2) Download a binary editor (I used bed, at
http://bedlinux.tripod.com/\), and edit the appropriate
asp*.o file. Change gcc2_compiled to gcc3_compiled.
Who knows what this might cause to happen, but it's
working for me - YMMV. Recompile & install.
Enjoy, and good luck!

ok... maybe im just being stupid here... but i tried both
suggestions..."For now, you have two options:

however I used hexedit to change gcc2 to gcc3 and it did
nothing..
then when i decided to deleted out the source code and re
downlaod it from the cvs .. then i tried to force it.. and i
got nothing... Obviously if im posting here im using redhat 8.
whoever can come up with a solid answer is the beter man/woman.
Just for my and everyone elses information ... does anyone
know of any good disassemblers in linux... or is this going
to be another ::cringes:: win32 project?

Hi,
thanks for the help, but I had to do more changes to make it
work.
1) line 66 in au_vortex.h: change malloc.h to slab.h
2) line 59 in Makefile: change pentium to cpu=pentium
3) Change your ln command above to symbolic link, i.e. ln -s
I'm not sure if there is any better way, but at least now it
works for me!

alright i got it working by doing what he said above
(besides editing the file)
but after i reboot i can't load the mod with "insmod -f
au8830" cause i get unresolved symbols. to get around this i
figured something out:
u need to do:
insmod soundcore
insmod -f au8830
this works for me so hopefully it'll help others out

I use this way in SuSE Linux 8.2 Professional.
1) Force the module to load with insmod -f, probably in
rc.local or whereever.
I hope to test another way as soon
Anyone knows excellent hex edit?

What I Stupid do it!
I don't read below comment
....
thanx below
however where is the source file in this driver?
I so sad...

I had changed from gcc2 to gcc3 in the au8810.o using emacs. This is
working
thanks,
