This is strange, I have bootstrapped GnuTLS on completely freshly
installed Debian and Ubuntu systems without problems.  Instead of
looking at patches to solve some intermediate problem, can you quote the
complete output you get by doing the steps describe by README-alpha on
your machine?  I.e:

$ # install all dependencies according to README-alpha
$ git clone git://
$ cd gnutls
$ make
$ make

It's generated by the bootstrap process.  There must have been an
earlier problem.  Most of your problems also seems to be a consequence
of broken bootstrapping.

Yep, it is just a warning.  Would be nice to fix, but isn't critical,
and isn't related to your build problems.

Yep.  Before working on fixing warnings, I suggest using the most recent
GCC version to make sure you aren't fixing broken compiler warnings.

No, I don't want any generated files in git.  It causes a lot of
problems for people with different auto* tool versions.  More severe
problems than what you are seeing now, actually.

I have autoconf 2.65, automake 1.11.1, and libtool 2.2.6b.  Straight
from Debian testing.

Yeah, but it should still work, and we use the old names for
compatibility with older Libtool versions.  But maybe we should drop

Changing that doesn't result in any code difference with modern tools,
it just means older Libtool won't work with GnuTLS.  In Libidn I have
this comment:

# We can't replace this with LT_INIT([win32-dll]) yet.  For example,
# the Ubuntu 8.04 LTS is still shipping a libtool version that doesn't
# have it.

I'm not sure GnuTLS trunk really bootstraps on Ubuntu 8.04 LTS any more
