autogen.sh in gst-template gives error

[Alex Song]

Hello,

I'm new to gstreamer and I'm trying to write a plugin. I started according to
"Plugin Writer's Guide" and downloaded gst-template. But when I did


./auto-gen.sh

I got

src/Makefile.am:6: Libtool library used but `LIBTOOL' is undefined
src/Makefile.am:6:   The usual way to define `LIBTOOL' is to add `AC_PROG_LIBTOOL'
src/Makefile.am:6:   to `configure.ac' and run `aclocal' and `autoconf' again.
src/Makefile.am:6:   If `AC_PROG_LIBTOOL' is in `configure.ac', make sure
src/Makefile.am:6:   its definition is in aclocal's search path.
src/Makefile.am: installing `./depcomp'
Makefile.am: installing `./INSTALL'
autoreconf: automake failed with exit status: 1
autogen.sh failed

I tried installing libtool 2.2.6b to /usr/local and tried to put
AC_PROG_LIBTOOL to configure.ac but they didn't help.

How to fix this issue?

Thanks very much,

Alex
