[plt-scheme] Accessing modules in a stand-alone executable

David, I'm of aware of separately compiled modules
like you mention. But that leaves the application
"spread out" into several files.

In order to avoid that, what I have been doing is to
compile the module file using the function
"compile-extension-parts-to-c" in the compiler
collection. I then compile the resulting .c file with
gcc. Then use "link-extension-parts" to produce a
_loader.so file that I link with my application. This
way all code gets located in a single executable file.

But, from what I understand, once a module is linked
with the application, _loader.so automatically loads
it. So in order to use it you have to use a require
statement on the form: (require mymodule).

Regards,

Ulf
