Automake Libtool 'No rule to make target'
I've been trying to build to GLTools library that accompanies The OpenGL SuperBible into a libtool library with automake.
I've set up autoconf and automake but when it comes to actually build the library I get:
$ make
make: *** No rule to make target `GLBatch.lo', needed by `libgltools.la'. Stop.
I've searched google as much as my sanity will let me and come up with nothing, I'm new to automake so I'm not quite sure what to be searching for. I'm sure it's either a tiny mistake or I've missed something fundamental.
Here is my Makefile.am:
ACLOCAL_AMFLAGS = -I m4
lib_LTLIBRARIES = libgltools.la
libgltools_la_SOURCES = GLBatch.cpp GLShaderManager.cpp GLTriangeBatch.cpp GLTools.cpp math3d.cpp glew.c
#libgltools_la_CFLAGS =
libgltools_la_LIBADD = -lX11 -lglut -lGL -lGLU -lm
include_HEADERS = GLBatchBase.h GLBatch.h GLFrame.h GLFrustum.h GLGeometryTransform.h GLMatrixStack.h GLShaderManager.h GLTools.h GLTriangleBatch.h math3d.h StopWatch.h GL/glew.h GL/glxew.h GL/wglew.h
EXTRA_DIST = autogen.sh
And my configure.ac if it matters:
# -*- Autoconf -*-
# Process this file with autoconf to produce a configure script.

Thanks very much.

It's hard to say based on your description but I would wager that you need to put your Makefile.am in the src directory and then create a Makefile.am in the GLTools directory that looks like this:
SUBDIRS = src
ACLOCAL_AMFLAGS = -I m4
It is also possible to do a non-recursive make but that requires some extra setup.
Here I did it for you:
