Building LO fails with autogen

[Jens Tröger]

Hello,

I just enlisted in a fresh core source tree to build a local copy of LO.
However, autogen fails.

  libreoffice > ./autogen.sh
  autoconf: invalid option -I
  Try `autoconf --help' for more information.
  Failed to run autoconf at ./autogen.sh line 158.

This is with the default GNU autoconf 2.52.  When I change line 158 in
autogen.sh to use autoconf-2.69 I get this:

  libreoffice > ./autogen.sh
  configure.ac:57: error: possibly undefined macro: AC_MSG_WARN
      If this token and others are legitimate, please use m4_pattern_allow.
      See the Autoconf documentation.
  configure.ac:117: error: possibly undefined macro: AC_MSG_CHECKING
  configure.ac:123: error: possibly undefined macro: AC_MSG_RESULT
  configure.ac:266: error: possibly undefined macro: AC_DEFINE
  configure.ac:3206: error: possibly undefined macro: AC_LANG_SOURCE
  configure.ac:3685: error: possibly undefined macro: AC_LANG_PUSH
  configure.ac:3698: error: possibly undefined macro: AC_LANG_POP
  configure.ac:4885: error: possibly undefined macro: AC_RUN_IFELSE
  Failed to run autoconf at ./autogen.sh line 158.

How can I fix this?  What are the tools dependencies here?
Jens
