See this threebit article on building an Apache modules using autoconf,
automake, and libtool:
http://threebit.net/tutorials/apache2_modules/tut1/tutorial1.html

You create the files configure.in and Makefile.am.  In the file
Makefile.am is where you specify your cpp file like so:
libmodfoo_la_SOURCES =3D mod_foo.c mod_bar.cpp

Good luck

Could you please tell me how you do that?
when i run my ./configure
--activate-module=3Dsrc/modules/mod_foo/mod_foo.cpp \
enable-module=3Dmod_foo

it gives me the error
Configuring for Apache, Version 1.3.34
 + using installation path layout: Apache (config.layout)  + activated
clickout module (modules/mod_foo/mod_foo.cpp
configure:Error: No such module named 'mod_foo'

could you please tell me how you use autoconf/libtool, or atleast
provide me pointers as to how they are used?
