Hello, in short, to fix sudo, run: patch -i ltsugar.m4.patch acsite.m4 Gory details follow: ;-) On Thu, Aug 23, 2007 at 07:53:27PM +0200, Dan Horák wrote: > Peter Vrabec píše v Čt 23. 08. 2007 v 18:02 +0200: > > $ cvs -d anoncvs@xxxxxxxxxxxxxxx:/cvs get sudo > > $ cd sudo > > $ autoreconf > > /usr/bin/m4:configure.in:2321: ERROR: recursion limit of 1024 exceeded, > > use -L<N> to change it > > autom4te: /usr/bin/m4 failed with exit status: 1 ... > Another iteration - it is libtool Indeed, it is. > my versions: > libtool-1.5.22-6.1.x86_64 > autoconf-2.61-2.noarch But note that your installed libtool-1.5.22 is not used at all. (Actually, libtool-1.5 does not use any macro named LT_INIT.) All libtool components which come into the play are already checked to the sudo cvs tree. Most importantly, the libtool m4 macro files from libtool-1.9f are stored in acsite.m4. IOW, acsite.m4 is a slightly edited (!) version of cat libtool.m4 ltoptions.m4 ltsugar.m4 ltversion.m4 OTOH, the Autoconf version matters; if you use Autoconf 2.59, like the sudo developers, it works. The infinite looping is around m4_car and m4_cdr, from m4sugar.m4 from Autoconf. When someone broken, errm, I mean, when I fixed the implementation of those two macros, the macro lt_combine from ltsugar.m4 stopped working. Ralf Wildenhues has immediately fixed the problem; the fix can be extracted from the libtool CVS: export CVSROOT=:pserver:anonymous@xxxxxxxxxxxxxxxxxxxx:/cvsroot/libtool cvs -z3 co -r branch-2-0 libtool/m4 cvs diff -u -r 1.2.2.1 libtool/m4/ltsugar.m4 >ltsugar.m4.patch For your convenience, I'm attaching the patch here, together with the corresponding ChangeLog entries. I'm going to submit the patch to the sudo project in a few minutes. Have a nice day, Stepan
2005-06-27 Stepan Kasal <kasal@xxxxxx> * m4/ltsugar.m4 (lt_combine, _lt_combine): Fix default separator. 2005-06-17 Ralf Wildenhues <Ralf.Wildenhues@xxxxxx> * m4/ltsugar.m4 (lt_car, lt_cdr): New macros, clones of m4_car/m4_cdr with the fixed semantics of Autoconf-2.59c CVS, in order to work with 2.59. (lt_combine): Use it. Reported by Christoph Egger <Christoph_Egger@xxxxxx>. 2005-06-11 Ralf Menzel <menzel@xxxxxxxxxxxxxxxxxxxxxx>, Ralf Wildenhues <Ralf.Wildenhues@xxxxxx> * m4/ltsugar.m4 (lt_combine): Don't test against empty quotes, test against empty arg. Fixes infinite m4 loop with CVS Autoconf.
