Guys,

  I have a libtool problem that occurs in the trinity build of tdeutils
(kdeutils) which includes libtool (2.2.6b Debian-2.2.6b-2ubuntu1). I have
libtool 2.4.2 installed on my system. The 'libtool' executable created by
./configure fails to declare or initialize 'to_tool_file_cmd'. This results in a
build failure for every file when make is run. (the call in the libtool file is):

$to_tool_file_cmd $1  (or "" $1 when uninitialized)

  I have included a link to the trinity desktop bug report below that provides
more details. What I need to know is "What's the best way to fix this?" I have a
work-around that explicitly sets to_tool_file_cmd to its default
�func_convert_file_noop� (post-configure using sed), but I need to know is this
a bug in libtool that allows the variable to remain uninitialized?"

  Running 'libtool --force' or 'autoreconfig --force' does not correct the
issue. I would appreciate any thoughts you would have.

Trinity bug report with additional details is here:

http://bugs.pearsoncomputing.net/bugzilla/show_bug.cgi?id=924

  The basic build script that leads to this failure is the following:

  cd ${srcdir}/${pkgname#*-}
  cp /usr/share/aclocal/libtool.m4 ./admin
  cp /usr/share/libtool/config/ltmain.sh ./admin

  make -f admin/Makefile.common

  ./configure \
    --prefix=${TDEDIR} \
    --with-qt-dir=${QTDIR} \
    --sysconfdir=/etc \
    --localstatedir=/var \
    --enable-debug=full \
    --enable-closure

  make

  In order for libtool to work, I have to include the following after
./configure to fix the libtool executable created:

sed -i '/#! \/bin\/sh/s|$|\n\nto_tool_file_cmd=func_convert_file_noop\n|' libtool

  What say the experts?

It looks like this isn't getting set to the default in libtool.m4, but 
it's strange that our test suite didn't notice (and that this is the 
first report of it).

Could you please send me a failing build log, and perhaps run a failing 
libtool command with an added --debug flag (right after the 'libtool') 
and send the output of that also.

Then we can come up with a test that fails, right now it seems the fix 
is something like:

diff --git a/m4/libtool.m4 b/m4/libtool.m4
index 75bfdb4..45a988f 100644
--- a/m4/libtool.m4
+++ b/m4/libtool.m4
@@ -7862,6 +7862,9 @@ case $host in

That's not correct, above the outer case, there's
[#assume ordinary cross tools, or native build.
lt_cv_to_tool_file_cmd=func_convert_file_noop

My guess is a version mismatch between libtool.m4 and ltmain.{m4}sh,
or something such.

Cheers,
Peter

Indeed, I totally missed that!

Yes, seems more likely.

I think there is another copy of a different version libtool.m4 inculded 
in acinclude.m4, and that's causing the problem

The libtool m4 macros that match the ltmain script do properly set these 
variables as Peter noted yesterday.

To update the included libtool, you will have to edit acinclude.m4 also.

Thanks,
Peter
