Im trying to install ffmpeg on my server. Im unsing centos 5.

When I try to install libfdk_aac I get the following error

` autoreconf: Entering directory `.'
autoreconf: configure.ac: not using Gettext
autoreconf: running: aclocal --force -I m4
autoreconf: configure.ac: tracing
autoreconf: configure.ac: not using Libtool
autoreconf: running: /usr/bin/autoconf --force
autoreconf: configure.ac: not using Autoheader
autoreconf: running: automake --add-missing --copy --force-missing
Makefile.am:31: Libtool library used but `LIBTOOL' is undefined
Makefile.am:31:
Makefile.am:31: The usual way to define `LIBTOOL' is to add `AC_PROG_LIBTOOL'
Makefile.am:31: to `configure.ac' and run `aclocal' and `autoconf' again.
Makefile.am: C objects in subdir but `AM_PROG_CC_C_O' not in `configure.ac'
autoreconf: automake failed with exit status: 1 `

If i type which libtool I get /usr/bin/libtool, so i think libtool is installed. So im not sure why this error is happening.

Thanks for any advice

The error is telling you that either libtool is not installed, or that you are not checking for it in configure.ac. Add the line LT_INIT in configure.ac. If autoreconf then complains that it doesn't know what LT_INIT is, you should either install libtool, upgrade your installation of libtool or use the deprecated AC_PROG_LIBTOOL in configure.ac. (AC_PROG_LIBTOOL should be replaced by LT_INIT in newer projects.)
