OK everyone, thanks for the help; I think I've got it. The
biggest help was actually "I have been compiling under Woody for
some time, it has to be something about your setup." That gave
me the inspiration to look very deep.
For the record, I am working from the 2.4.16 sources.
The error is in the way the standard Makefile interacts with
bash, and it occurs in the symlinks rule:
rm -f include/asm
( cd include ; ln -sf asm-$(ARCH) asm)
@if [ ! -d include/linux/modules ]; then \
mkdir include/linux/modules; \
The problem is, if you run /bin/sh (which is a symlink to bash),
then the command
( cd include ; echo ln -sf asm-$(ARCH) asm)
fails with an error:
sh: cd: include: No such file or directory
If you run bash as "bash" that kind of thing works fine.
So the include/asm link is never created. This missing link
would seem to be the cause of my problems under most of the
situations I described. After fixing this, I was able to build
my kernel without problem.
Now, I'm not a shell expert. Does the Makefile need a bug
report, or does bash?
