how to install headers? what about building dependent libraries?

[Giovanni Bricconi]

I'm new to automake and autoconf, I'm now trying to write my first 
project using these tools.
My project consists in a library and a sample apache module that depends 
on this library.
The directory structure I have chosen is the following:

      my_project (contains configure.ac and top Makefile.am)

       -> includes (the includes to be installed to use the library,
       used by sources and random_module)
       -> sources (the sources of the library)
       -> random_module (the sample)

I have tried to set up configure.ac and Makefile.am reading info 
documentation, actually I'm able to compile the project but I have still 
some problems.

  1. make install installs the library and the sample module, but does
     not install the headers
  2. the library built in sources and the apache module are compiled
     using libtool, I was able to introduce a dependence between the
     module and the library but libtool statically links in the
     library. I would like the sample module to be linked with the
     shared library, how can I do that?

Here are my configure.ac and makefile.am, every comment will be 
apreciated, I have a lot to learn about autoconf & automake

the Makefile.am in includes directory, does not work, if I call make 
install from includes headers get installed, i I call make install from 
the top directory headers does not gets installed.

include_HEADERS = gb_allocators.h gb_pthreadstuff.h gb_new.h gb_Pool_Allocator.h


The Makefile.am in random_module directory, compiling it libgbap il 
statically linked, I would like to link random_module to libgbap shared 
object.

CXXFLAGS+=-I${top_srcdir}/includes address@hidden@ -pthread

noinst_LTLIBRARIES =

if RANDOM_MODULE
noinst_LTLIBRARIES += random_module.la
endif

random_module_la_LDFLAGS = -module -rpath '@APXS_LIBEXECDIR@' 
../sources/libgbap.la

random_module_la_SOURCES = Variabile.cpp Random.cpp mod_random.cpp

#install-exec-local
install-data-local:
   @APXS@ -i -n 'random_module' random_module.la 


The library's Makefile.am (works)

CXXFLAGS+=-I${top_srcdir}/includes address@hidden@ -pthread

lib_LTLIBRARIES = libgbap.la

libgbap_la_SOURCES = gb_pthreadstuff.cpp win_threads.cpp
