Comment 1 Rik van Riel 2004-06-11 08:13:24 EDT
RHL9 is no longer supported, sorry.

Also, it does compile just fine using gcc. In fact, many of the
drivers shipped in RHL9 included hardirq.h and they all compiled fine.

You're not using icc, are you ? ;)
Comment 2 Charlie MacDonald 2004-06-11 13:04:39 EDT
Interesting then that using gcc gives this error "/lib/modules/2.4.20-
31.9/build/include/asm/hardirq.h:17:33: #if with no expression" when 
compiling isn't it?  I just thought that since it was your release of 
the kernel code that gives the error someone else might have 
encountered the same problem and wanted a quick fix.  This error 
didn't occur while compiling the same modules (Compaq's cpqasm and 
cpqevt modules for the Proliant server series) with the 2.2 series of 
kernel (both RedHat's and kernel.org) or 2.4.7-10 (RedHat).  The 
include file is wrong since adding three characters allows these 
modules to compile successfully....just my opinion of course, but 
that's the nature of GPL isn't it?  And it's not a Redhat 9 issue per-
se (unless RedHat now owns the kernel source code ;) ), but a kernel-
2.4.20 issue you'll probably find the same error in all 2.4.20
