c - error: Libtool library used but 'LIBTOOL' is undefined

Question

I am trying to automake the OrientDb C++ library, but getting some errors.

Makefile.am:10: error: Libtool library used but 'LIBTOOL' is undefined
Makefile.am:10:   The usual way to define 'LIBTOOL' is to add 'LT_INIT'
Makefile.am:10:   to 'configure.ac' and run 'aclocal' and 'autoconf' again.
Makefile.am:10:   If 'LT_INIT' is in 'configure.ac', make sure
Makefile.am:10:   its definition is in aclocal's search path.

I have configure.ac and Makefile.am already defined.

I run the following autotools

• aclocal

• autoheader

• automake:

libtool (GNU libtool) 2.4.2

configure.ac

# -*- Autoconf -*-
# Process this file with autoconf to produce a configure script.

AC_PREREQ([2.69])
AC_INIT([orientdb-c],[0.9])
AC_CONFIG_SRCDIR([src/o_query_internal.h])
AC_CONFIG_HEADERS([config.h])
AM_INIT_AUTOMAKE()

# Checks for programs.
AC_PROG_CXX
AC_PROG_AWK

LT_INIT

# Checks for libraries.

# Checks for header files.
AC_CHECK_HEADERS([malloc.h memory.h netdb.h netinet/in.h stdlib.h string.h sys/ioctl.h sys/socket.h     sys/time.h unistd.h])

# Checks for typedefs, structures, and compiler characteristics.
AC_TYPE_SIZE_T

# Checks for library functions.
AC_FUNC_MALLOC
AC_FUNC_REALLOC

Things I already tried:

• autoreconf

• aclocal -I /usr/share/libtool

• aclocal -I .

A good answer for me was to install libtool:

sudo apt-get install libtool
