Subject: [PATCH] kbuild: build TAGS problem with O=
X-Git-Tag: v2.6.12.4~13
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ab998a6790272b6f45a63d9ef763efd435eae23a;p=thirdparty%2Fkernel%2Fstable.git

[PATCH] kbuild: build TAGS problem with O=

For inclusion into 2.6.12.stable, extracted from current Linus git:

[PATCH] kbuild: build TAGS problem with O=

  make O=/dir TAGS

  fails with:

    MAKE   TAGS
  find: security/selinux/include: No such file or directory
  find: include: No such file or directory
  find: include/asm-i386: No such file or directory
  find: include/asm-generic: No such file or directory

  The problem is in this line:
  ifeq ($(KBUILD_OUTPUT),)

KBUILD_OUTPUT is not defined (ever) after make reruns itself.  This line is
used in the TAGS, tags, and cscope makes.
