*.a and *la files

[Rodrigo Ramos <crackduoro@xxxxxxxxx>]

Hi List

I hope be the correct list. I explain my issue:

When I trye compile Apache 2 the compilation make all good, but when I 
look into the modules folder I get files with extension *.la and *.a, 
but never get *.so files. For example: 

httpd.exp            mod_authn_default.la    mod_cern_meta.a    mod_log_config.la    mod_speling.a
mod_actions.a           mod_cern_meta.la  mod_expires.a          mod_speling.la
mod_actions.la

My SO is Red Hat Enterprise Linux Server release 5.6 (Tikanga).
My kernel is 2.6.18-238.el5 
My Arch is x86_64 x86_64 x86_64

My compile options are: 

./configure --prefix=/xxx/xxx/APACHE2.2.17 --enable-shared=ssl 
--enable-shared=max --enable-module=so --enable-mods-shared=all 
--enable-so

So, I compiled with the same compile options in Ubuntu and generate all OK

What could it be?

Greetings
