Build error -> libtool: link: CURRENT `XXX.lo' is not a nonnegative integer

[Etienne M. Gagnon]

Hi There!

I'm having a little problem with libtool on Debian (unstable).  I would
very much appreciate your help.  Here are the details.

My work-in-progress version of SableVM uses autoconf (2.52-1), automake
(1.4-p4-1) and libtool (1.4b-3).

Everything used to build nicely until lately.  But, today the build
process seems broken.  Here's what happens:

$ aclocal
$ autoconf
$ autoheader
autoheader2.50: src/include/config.h.in is unchanged
$ automake -a
$ ./configure --prefix=/home/egagnon/work
...
checking whether the g++ linker (/usr/bin/ld) supports shared
libraries... yes
ltcf-cxx.sh: error: problem compiling test program

checking if g++ supports -c -o file.o... no
...
config.status: creating src/include/config.h
$ make
...

libtool: link: `libsablevm.lo' is not valid version information
make[3]: *** [libsablevm.la] Error 1
...

I do not have any idea what this error message is about.  The version
information in 
configure.ac used to work well.  Here it is:

...
PACKAGE="sablevm"
VERSION="0.1.6"
BUG-REPORT-ADDRESS="http://www.sablevm.org/";
LIBVERSION="0:6:0"

AC_INIT(${PACKAGE}, ${VERSION}, ${BUG-REPORT-ADDRESS})
AC_CONFIG_SRCDIR([src/sablevm/sablevm.c])

AC_SUBST(PACKAGE)
AC_SUBST(VERSION)
AC_SUBST(LIBVERSION)

AM_INIT_AUTOMAKE(${PACKAGE},${VERSION})
AM_CONFIG_HEADER(src/include/config.h)
...

And in src/libsablevm/Makefile.am:

lib_LTLIBRARIES = libsablevm.la
...
libsablevm_la_LIBADD = -lpthread -lm -ldl -lffi -lltdl
libsablevm_la_LDFLAGS = -version-info @LIBVERSION@
...


Where should I start looking, to find the cause of this build error?  If
you think it is a libtool problem (as I strongly suspect), can I help
you finding it, or do you absolutely want me to send you a .tar.gz file
of my current work-in-progress snapshot?

Thanks in advance for your help.

Etienne
