Ulrich, Ok, I did my make mrproper, and the make dep is running now. I'll post my results after the make modules is done. Go eat dinner or something, you're working too late again from home. :) Mark Post -----Original Message----- From: Ulrich Weigand [mailto:weigand@immd1.informatik.uni-erlangen.de] Sent: Friday, October 19, 2001 5:01 PM To: mark.post@eds.com Cc: LINUX-390@VM.MARIST.EDU Subject: Re: RedHat Beta - netiucv.o unresolved symbol Mark Post wrote: >From what I can tell, they have on the ac14 patch.

Therefore the symbol names don't match (they are supposed to match *exactly*, including the argument type mangling stuff appended by symbol versioning). Now I have no idea why this would be the case; the build process should build everything correctly (unless you've done things like changing configure options between 'make image' and 'make modules'?) ... Sometimes the 2.4 build process gets confused; in that case a complete rebuild starting with a 'make mrproper' will get things in order again.
