Hello,

I'm kinda new to this kernel hacking thing. So excuse me for any stupid questions/remarks. The problem I have occurs because I'm trying to install the rshaper software on my linux system. I'm running:
Distribution: red hat 6.2
Kernel ver.: 2.2.14-5.0
System: i386
compiler: gcc
compiler ver.: gcc version egcs-2.91.66 19990314/linux (egcs-1.1.2 release)

The rshaper software requires you to modify the 8390 driver kernel module. I had no problems modifying the 8390.c source to accomodate rshaper. The problem is that the ne2k-pci.o uses symbols from the 8390.o driver. these symbols are exported with the EXPORT_SYMBOL macro.
When I load the modified 8390.o (insmod 8390.o)
my /proc/ksyms shows that the exported symbols from 8390.o are different from the other symbols because they have "_R__ver_" in front of them. And when I load the ne2k-pci.o it complains that it can't find those symbols that were supposed to be exported by 8390.o

I have looked around on the net and this problem seems related to the CONFIG_MODVERSIONS bug. since I have no clue as to getting these symbols to be exported correctly maybe someone can tell me how to get around this problem.

the compile command I used to compile 8390.c was:
gcc -D__KERNEL__ -DEXPORT_SYMTAB -DMODULE -I/usr/src/linux/net/inet -Wall -Wstrict-prototypes -O6 -m486 -c 8390.c

greetings,
Willem van Doesburg
