autoconf 2.68 errors

[Naresh Kumar Panthangi]

Hi All,

I'm new to autoconf. I have been building an application which will use
autoconf 2.68.

autoconf 2.68 is throwing below errors. Please find the errors list below:

=======================================================
build_script : Running reautoconf script
Autoconf in './ilnclient'
configure.in:112: error: AC_LANG: unknown language:
../../lib/autoconf/lang.m4:82: _AC_LANG_SET is expanded from...
../../lib/autoconf/lang.m4:89: AC_LANG is expanded from...
/home/panthangi/aaa/aaahpsrc/trunk/server/aclocal.m4:975: AC_CHECK_ALL_TOOLS
is expanded from...
configure.in:112: the top level
autom4te: /usr/local/bin/m4 failed with exit status: 1
========================================================

If I use autoconf 2.13, the autoconf generates configure scripts without any
errors.

Could anyone please help me how to resolve these errors in autoconf 2.68 ?

And Can I have any tool which will automatically convert the
configure.infiles (which were
written for autoconf 2.13) from 2.13 to autoconf 2.68.

PS: I'm using m4 (GNU M4) 1.4.15 version.and libtool 2.4 version.
Thanks in advance.
