Hi, I'm trying to build GNU Classpath CVS HEAD on Mac OS X 10.6.7. I followed these instructions to satisfy the autoconf 2.65 requirement: http://www.mattvsworld.com/blog/2010/02/install-the-latest-autoconf-and-automake-on-mac-os-10-6/ However, when I try to run 'autogen.sh' I get the following error: $ sh autogen.sh configure.ac:503: warning: AC_LIB_PREPARE_PREFIX is m4_require'd but not m4_defun'd m4/iconv.m4:11: AM_ICONV_LINKFLAGS_BODY is expanded from... m4/iconv.m4:22: AM_ICONV_LINK is expanded from... m4/iconv.m4:77: AM_ICONV is expanded from... configure.ac:503: the top level configure.ac:503: warning: AC_LIB_RPATH is m4_require'd but not m4_defun'd configure.ac:503: warning: AC_LIB_PREPARE_PREFIX is m4_require'd but not m4_defun'd m4/iconv.m4:11: AM_ICONV_LINKFLAGS_BODY is expanded from... m4/iconv.m4:22: AM_ICONV_LINK is expanded from... m4/iconv.m4:77: AM_ICONV is expanded from... configure.ac:503: the top level configure.ac:503: warning: AC_LIB_RPATH is m4_require'd but not m4_defun'd libtoolize: putting auxiliary files in `.'. libtoolize: copying file `./ltmain.sh' libtoolize: putting macros in AC_CONFIG_MACRO_DIR, `m4'. libtoolize: copying file `m4/libtool.m4' libtoolize: copying file `m4/ltoptions.m4' libtoolize: copying file `m4/ltsugar.m4' libtoolize: copying file `m4/ltversion.m4' libtoolize: copying file `m4/lt~obsolete.m4' configure.ac:503: warning: AC_LIB_PREPARE_PREFIX is m4_require'd but not m4_defun'd m4/iconv.m4:11: AM_ICONV_LINKFLAGS_BODY is expanded from... m4/iconv.m4:22: AM_ICONV_LINK is expanded from... m4/iconv.m4:77: AM_ICONV is expanded from... configure.ac:503: the top level configure.ac:503: warning: AC_LIB_RPATH is m4_require'd but not m4_defun'd configure.ac:503: warning: AC_LIB_PREPARE_PREFIX is m4_require'd but not m4_defun'd m4/iconv.m4:11: AM_ICONV_LINKFLAGS_BODY is expanded from... m4/iconv.m4:22: AM_ICONV_LINK is expanded from... m4/iconv.m4:77: AM_ICONV is expanded from... configure.ac:503: the top level configure.ac:503: warning: AC_LIB_RPATH is m4_require'd but not m4_defun'd configure:17858: error: possibly undefined macro: AC_LIB_PREPARE_PREFIX If this token and others are legitimate, please use m4_pattern_allow.
