>Applications also depend on other components, they have predicates, sometimes
they need linker options; there seems to be only little difference between
applications (stand-alone programs) and packages. If you want to use the
findlib mechanisms for applications, too, the following trick helps.</P
><P
>The environment variable <TT
CLASS="LITERAL"
>OCAMLPATH</TT
> may contain a
colon-separated path of possible sitelib locations. It is allowed to include
"." into the path (Shell commands follow):
<PRE
CLASS="PROGRAMLISTING"
>OCAMLPATH=.
export OCAMLPATH</PRE
>
This makes ".", i.e. your current directory, another sitelib location. You may
now put the components of your applications into subdirectories together with
META files; the hierarchy might look as follows:
<PRE
CLASS="PROGRAMLISTING"
>./Makefile global Makefile
./localpkg1/META first local package directory: Contains META
./localpkg1/... ... and more
./localpkg2/META second local package dir: Contains META
./localpkg2/... ... and more
...</PRE
>
From findlib's point of view, these directories are now package directories,
and you can refer to them on the command line:
<PRE
CLASS="PROGRAMLISTING"
>ocamlfind ocamlc -o ... -linkpkg -package localpkg1,localpkg2,...</PRE
>
If you do not want subdirectories, you can also refer to the META file in the
same directory by the name ".", e.g.:
<PRE
CLASS="PROGRAMLISTING"
>ocamlfind ocamlc -o ... -linkpkg -package .</PRE
>
In this case, the linking information will be taken from
<TT
CLASS="LITERAL"
>./META</TT
>.</P
