Thread: separate objdir Makefile regression in 2.6.24-rc*

  1. separate objdir Makefile regression in 2.6.24-rc*


    2.6.24-rc5 doesn't seem to create Makefiles in empty obj dirs anymore

    With 2.6.24-rc5:

    % mkdir obj-test
    % cd obj-test/
    % make -C ../linux O=$(pwd) allnoconfig >/dev/null
    grep: /home/lsrc/quilt/obj-test/Makefile: No such file or directory
    % make
    make: *** No targets specified and no makefile found. Stop.
    %

    With 2.6.23 this worked:

    % mkdir obj-test
    % cd obj-test/
    % make -C ../linux-2.6.23 O=$(pwd) allnoconfig >/dev/null
    % make
    make -C /home/lsrc/linux-2.6.23 O=/home/lsrc/obj-test
    GEN /home/lsrc/obj-test/Makefile
    scripts/kconfig/conf -s arch/x86_64/Kconfig
    Using /home/lsrc/linux-2.6.23 as source for kernel
    ....

    Ah, thanks. But it looks like that patch isn't in Linus' tree yet. Sam?
