Hello.
I use HHL CDK v1.2 and use linux-2.4.3-pre3-2001-03-11(W.Denk's patched
kernel).
When I compile small module program, I got following message.
Could someone help me with this problem??
[root at ssljm 8xx_io]# make -f Makefile.test

{standard input}: Assembler messages:
{standard input}:6: Warning: Ignoring changed section attributes for .modinfo
[root at ssljm 8xx_io]#
although this warning, I got test.o object file and I could loading test.o by
insmod test.o
but I got another problem.
Warning: Kernel module version mismatch
test.o was compiled for kernel version 2.2.14
while this kernel is version 2.4.3-pre3
any comments will help us.
thanks..
