[Modcaml] install problem

[Christophe Dehlinger]

Hi,

I'm having trouble installing CocanWiki.  I hope this is the right place 
to ask for help...

Anyway, I've been trying to install this fine piece of software on my 
linux box at work (old Red Hat, dates back to June '02), for which I do 
not have root access.
I installed locally everything listed on 
http://sandbox.merjis.com/dependencies in order, except the DBI 
libraries that I had missed and thus installed at the very end. I always 
used the latest version, except for Apache, where I stuck to the latest 
1.3 release as it seemed easier to interface with mod_caml.
I then compiled CocanWiki, without any problem.

However, I have a lot of trouble configuring Apache. By the way, I'm a 
complete Apache noob.

I didn't set up the Virtual Host thing, because as I understand it I 
would have needed several IP addresses or some kind of control on the 
network.
So I altered the httpd.conf file this way:
- changed the listen port (port 80 is blocked here, I put 16000 instead)
- changed the DocumentRoot to CW's html directory
- added the following at the end of the file
   AddDefaultCharset utf-8
   LoadModule caml_module /.../apachehttpd/libexec/mod_caml.so
   CamlLoad /.../cocanwiki-1.3.12/html/_bin/cocanwiki.cma
   Include /.../cocanwiki-1.3.12/conf/cocanwiki.conf

I then tried to start apache. It didn't work, I got this exception:
Failure("error while linking 
/home/irsrvhome1/R11/dehlingc/oc/cocanwiki-1.3.12/html/_bin/cocanwiki.cma.
Reference to undefined global `ExtString'")

I then added CamlLoad directives until these failures disappeared. At 
the end, the tail of httpd.conf was:
AddDefaultCharset utf-8
LoadModule caml_module /.../apachehttpd/libexec/mod_caml.so
CamlLoad /.../mod_caml/registry.cmo
CamlLoad /.../lib/ocaml/nums.cma
CamlLoad /.../lib/ocaml/site-lib/extlib/extLib.cma
CamlLoad /.../lib/ocaml/site-lib/postgres/postgres.cma
CamlLoad /.../lib/ocaml/dbi/dbi.cma
CamlLoad /.../lib/ocaml/dbi/dbi_postgres.cmo
CamlLoad /.../lib/ocaml/site-lib/calendar/calendar.cma
CamlLoad /.../cocanwiki-1.3.12/html/_bin/cocanwiki.cma
Include /.../cocanwiki-1.3.12/conf/cocanwiki.conf

But it still doesn't work, and now I really don't know what to do. 
Apache startup fails in the Include line with:
Syntax error on line 25 of /.../cocanwiki-1.3.12/conf/cocanwiki.conf:
Invalid command 'ExpiresActive', perhaps mis-spelled or defined by a 
module not included in the server configuration
../bin/apachectl start: httpd could not be started

Any suggestions welcome :)

Cheers,
Christophe
