I cross compile arm and mips kernels from the same kernel tree.  When

I build a kernel the first time with a fresh kernel tree, the

include/asm symlink is set properly.  However, when I compile for a

different $ARCH, the include/asm is not changed and the build fails.


Would it be possible for the build system to update the include/asm

symlink when it doesn't correspond to the architecture you're

currently trying to build for?

You are not the first to ask for this - suprise.

Alexey point out a good solution but I have added to my tod list

to do something a bit more intelligent when ARCH changes.


The patches I have seen so far has been lacking fundamental functionality

and on top of this I hope to find a nice way to preserve CROSSCOMPILE

since that often change too.

You can use O= feature and skip this issue completely.


   make ARCH=mips O=../build/mips ...
