Re: [PLUG] Kernel compile error message

[LeRoy Cressy <ldc@netaxs.com>]

The top level Makefile has the following lines in it thus making the
include path equal

TOPDIR  := $(shell /bin/pwd)

HPATH           = $(TOPDIR)/include
FINDHPATH       = $(HPATH)/asm $(HPATH)/linux $(HPATH)/scsi $(HPATH)/net

CPPFLAGS := -D__KERNEL__ -I$(HPATH)

So the kernel has its own header path built into the Makefile and not
depending upon the C preprocessor default path.  Thus if VA Linux
changed the source Makefile variables and made them point to
/usr/include you can have problems with a kernel compile. 

You can use any normal kernel source from the kernel mirrors.  What some
manufacturers do is take out the parts of the kernel that are not needed
for the specific archecture, but if they are not careful something may
break, which seems to have happened in your case.
