Not sure what happened to that previous email.
Here's a repeat.
The command I could quickly find was as follows:
cp -a ../src/linux/include/`ls -l --color=none \
../src/linux/include/asm|cut -f 28 -d " "` asm
Pretty ugly if you ask me. It can be done with awk much
simpler, but I forgot to write down the command and I forgot what i
exactly had. Bottom line is that i don't think it's worth it using a
complex command like that just to copy a directory over. There are no
symlinks in the kernel include directories so not a big deal now. It
would be nice, though, if we can change it.
An alternative could be:
cd $LFS/usr/include &&
mkdir asm && cp -a ../src/linux/include/asm/* asm
Sigh, ok I think I like that better than cp -R that I just changed it
Normally I'd just wait before changing things and discuss it first. But
I thought this was such a trivial thing it wouldn't really need
discussing. Seems that even the smallest thing can be a pain to figure
out. Or is it just me?
Anyways, I've tested the mkdir asm && cp -a ../src/linux/include/asm/*
asm thing and it works as expected. I've moved on to the next section in
chapter 5 so I won't be changing the kernel part anymore myself before I
really break something there ;)
