I've been using Emacs compiled from cvs (now bzr) for several years. It has been about 6 months since I last built and am now getting errors due to autoconf requirements having been raised. I'm running on CentOS 5.4 and autoconf is at 2.59 there. So I downloaded latest versions of autoconf (2.68), m4 (1.4.16), and automake (1.11) and built all from source and was able to get further... autoconf didn't work.. 'autoreconf --install' got further but also failed: $ autoreconf --install configure.in:646: installing `./compile' configure.in:378: installing `./config.guess' configure.in:378: installing `./config.sub' configure.in:28: installing `./install-sh' configure.in:28: installing `./missing' lib/gnulib.mk:30: GL_GENERATE_ALLOCA_H does not appear in AM_CONDITIONAL lib/Makefile.am:9: `lib/gnulib.mk' included from here lib/gnulib.mk:145: gl_GNULIB_ENABLED_dosname does not appear in AM_CONDITIONAL lib/Makefile.am:9: `lib/gnulib.mk' included from here lib/gnulib.mk:217: gl_GNULIB_ENABLED_be453cec5eecf5731a274f2de7f2db36 does not appear in AM_CONDITIONAL lib/Makefile.am:9: `lib/gnulib.mk' included from here lib/gnulib.mk:356: gl_GNULIB_ENABLED_sigprocmask does not appear in AM_CONDITIONAL lib/Makefile.am:9: `lib/gnulib.mk' included from here lib/gnulib.mk:367: gl_GNULIB_ENABLED_stat does not appear in AM_CONDITIONAL lib/Makefile.am:9: `lib/gnulib.mk' included from here lib/gnulib.mk:382: GL_GENERATE_STDARG_H does not appear in AM_CONDITIONAL lib/Makefile.am:9: `lib/gnulib.mk' included from here lib/gnulib.mk:410: GL_GENERATE_STDBOOL_H does not appear in AM_CONDITIONAL lib/Makefile.am:9: `lib/gnulib.mk' included from here lib/gnulib.mk:433: GL_GENERATE_STDDEF_H does not appear in AM_CONDITIONAL lib/Makefile.am:9: `lib/gnulib.mk' included from here lib/gnulib.mk:463: GL_GENERATE_STDINT_H does not appear in AM_CONDITIONAL lib/Makefile.am:9: `lib/gnulib.mk' included from here lib/gnulib.mk:740: gl_GNULIB_ENABLED_strtoll does not appear in AM_CONDITIONAL lib/Makefile.am:9: `lib/gnulib.mk' included from here lib/gnulib.mk:751: gl_GNULIB_ENABLED_strtoull does not appear in AM_CONDITIONAL lib/Makefile.am:9: `lib/gnulib.mk' included from here lib/gnulib.mk:1036: gl_GNULIB_ENABLED_verify does not appear in AM_CONDITIONAL lib/Makefile.am:9: `lib/gnulib.mk' included from here lib/Makefile.am: installing `./depcomp' autoreconf: automake failed with exit status: 1 Then ran: $ make extraclean [ -r "/home/me/src/emacs/trunk/src/config.in" ] || ( cd /home/me/src/emacs/trunk && autoheader ) cd /home/me/src/emacs/trunk && automake --gnu -a -c lib/Makefile lib/gnulib.mk:30: GL_GENERATE_ALLOCA_H does not appear in AM_CONDITIONAL lib/Makefile.am:9: `lib/gnulib.mk' included from here lib/gnulib.mk:145: gl_GNULIB_ENABLED_dosname does not appear in AM_CONDITIONAL lib/Makefile.am:9: `lib/gnulib.mk' included from here lib/gnulib.mk:217: gl_GNULIB_ENABLED_be453cec5eecf5731a274f2de7f2db36 does not appear in AM_CONDITIONAL lib/Makefile.am:9: `lib/gnulib.mk' included from here lib/gnulib.mk:356: gl_GNULIB_ENABLED_sigprocmask does not appear in AM_CONDITIONAL lib/Makefile.am:9: `lib/gnulib.mk' included from here lib/gnulib.mk:367: gl_GNULIB_ENABLED_stat does not appear in AM_CONDITIONAL lib/Makefile.am:9: `lib/gnulib.mk' included from here lib/gnulib.mk:382: GL_GENERATE_STDARG_H does not appear in AM_CONDITIONAL lib/Makefile.am:9: `lib/gnulib.mk' included from here lib/gnulib.mk:410: GL_GENERATE_STDBOOL_H does not appear in AM_CONDITIONAL lib/Makefile.am:9: `lib/gnulib.mk' included from here lib/gnulib.mk:433: GL_GENERATE_STDDEF_H does not appear in AM_CONDITIONAL lib/Makefile.am:9: `lib/gnulib.mk' included from here lib/gnulib.mk:463: GL_GENERATE_STDINT_H does not appear in AM_CONDITIONAL lib/Makefile.am:9: `lib/gnulib.mk' included from here lib/gnulib.mk:740: gl_GNULIB_ENABLED_strtoll does not appear in AM_CONDITIONAL lib/Makefile.am:9: `lib/gnulib.mk' included from here lib/gnulib.mk:751: gl_GNULIB_ENABLED_strtoull does not appear in AM_CONDITIONAL lib/Makefile.am:9: `lib/gnulib.mk' included from here lib/gnulib.mk:1036: gl_GNULIB_ENABLED_verify does not appear in AM_CONDITIONAL lib/Makefile.am:9: `lib/gnulib.mk' included from here make: *** [/home/me/src/emacs/trunk/lib/Makefile.in] Error 1 Has anyone successfully compiled GNU Emacs on CentOS-5?
