  • 1791ff717   kbuild: clean-up and bug fix of scripts/Makefile.host ... Browse Code »

    Assume we have a Makefile like this:

    hostprogs-y := foo
    foo-cxxobjs := bar/baz.o
    foo-objs := qux/quux.o

    In this case, Kbuild creates bar/ directory,
    but fails to create qux/ directory.

    This commit re-writes directory creation more simply,
    fixing that bug.

    The directory creation can be more simplified by two levels.

    [1] Drop $(dir ...)

    $(dir $(f)) always returns non-empty string.

    So, $(if $(dir $(f)),$(dir $(f)) is equivalent to $(dir $(f)).

    [2] Unroll $(foreach ...) loop

    $(dir ...) can take one or more arguments and returns a list of
    directories of them.

    $(foreach f, $(progs), $(dir $(f))) can be unrolled as $(dir $(progs)).

  • 62e221079   kbuild: drop shared library support from Makefile.host ... Browse Code »

    The shared library feature in Makefile.host is no longer used.
    Rip it off to keep the build infrastucture simple.

    Update Documentation/kbuild/makefiles.txt too.
    The section "4.3 Definition shared libraries" should be removed
    and the following sections should be re-numbered.

  • edb950c17   kbuild: fix a bug of C++ host program handling ... Browse Code »

    The comment claims:
    C++ executables compiled from at least one .cc file
    and zero or more .c files

    But C++ executables with zero .c file fail in build.

    For example, assume we have a Makefile like this:

    hostprogs-y := foo
    foo-cxxobjs := bar.o

    In this case, foo is treated as host-csingle
    and Kbuild tries to search non-existing foo.c source.

  • 5e8d780d7   kbuild: fix ia64 breakage after introducing make -rR ... Browse Code »

    kbuild used $¤(*F to get filename of target without extension.
    This was used in several places all over kbuild, but introducing
    make -rR broke his for all cases where we specified full path to
    target/prerequsite. It is assumed that make -rR disables old style
    suffix-rules which is why is suddenly failed.

    ia64 was impacted by this change because several div* routines in
    arch/ia64/lib are build using explicit paths and then kbuild failed.

    Thanks to David Mosberger-Tang for an explanation
    what was the root-cause and for testing on ia64.

    This patch also fixes two uses of $(*F) in arch/um

    This reverts commit e5c44fd88c146755da6941d047de4d97651404a9.

    Thanks to Daniel Ritz and Michal Piotrowski for noticing the problem.

    Daniel says:

    "[The] reason is a recent change that made modules always shows as
    module.mod. it breaks modprobe and probably many scripts..besides
    lsmod looking horrible

    stuff like this in modprobe.conf:
    install pcmcia_core /sbin/modprobe --ignore-install pcmcia_core; /sbin/modprobe pcmcia
    makes modprobe fork/exec endlessly calling itself...until oom
    interrupts it"

    make failed to supply the filename when using make -rR and using $(*F)
    to get target filename without extension.
    This bug was not reproduceable in small scale but using:
    $(basename $(notdir $@)) fixes it with same functionality.

  • 9870a93d3   kbuild: obj-dirs is calculated incorrectly if hostprogs-y is defined ... Browse Code »

    When Makefile.host is included, $(obj-dirs) is subjected to the
    addprefix operation for the second time. Prefix only needs to be added
    to the newly added directories, but not to those that came from
    Makefile.lib.

    This causes the build system to create unneeded empty directories in the
    build tree when building in a separate directory. For instance,
    lib/lib/zlib_inflate is created in the build tree.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
