    Hello,

    I have tried to build the latest master and got the following error:

    42sh> make O=~/works/linux-build/aarch64-4k -C ~/works/linux
    make: Entering directory '/home/julgra01/works/linux'
    Makefile:135: *** failed to create output directory "~/works/linux-build/aarch64-4k". Stop.
    make: Leaving directory '/home/julgra01/works/linux'

    The bisector found the commit 8e9b466 "kbuild: use $(abspath ...)
    instead of $(shell cd ... && /bin/pwd)".

    Looking at the code, it seems that it is because the code is
    now using $(realpath ...). Indeed when I replace ~ by $HOME
    the kernel is now built.

    I am not a Makefile expert, so I would appreciate if anyone
    could suggest a patch for this.


    Thanks for the report.

    Which shell are you using?

    I am using dash.


    I use bash and I have no problem.
    If I try dash, indeed, it fails.

    I will take a look.

    Thank you!

    Cheers,
