Howto link cmas with Ocamlbuild

Howto link cmas with Ocamlbuild

[Till Crueger]

Hi,

I am working on a small project that is going to include a dynamic  
webserver using Ocsigen and Eliom. I am using Ocamlbuild for the  
compilation. The project is also going to use Batteries and Sexplib. This  
means I need to include Sexplib and Batteries within the .cma file for  
Ocsigen to find the libraries. However when I use the Myocamlbuild plugin  
for Batteries the rules for linking cmas wont use linkpkg flag. Right now  
I compile the full project using ocamlbuild and then I have to repeat the  
last step manually. Is there a better way, to get ocamlbuild to include  
the necessary libraries in the .cma?

Thank you,
   Till

Hi,

It is not a good idea to include batteries and sexplib in your cma.

If your cma is a findlib package (i.e. has a META file with the right 
dependencies inside), Ocsigen server will automatically load the dependencies 
if you write
<library findlib-package="yourpackage"/>
or
<eliom findlib-package="yourpackage" />
in Ocsigen server's configuration file.

If your package does not have a META file, you need to load batteries and 
sexplib manually:
<library findlib-package="batteries"/>
<library findlib-package="sexplib"/>
