RE: [Gcl-devel] Module

[Mike Thomas]

Hi Leonardo.

 

Welcome to GCL.

 

I wanna create a binding of a language to GCL. Is there any guide of how to do that?  

Can you please give an example of what you mean by "binding" as I don't understand your question?

 

If you want to call C from GCL there is a foreign function interface specifically designed for that purpose.  Here is come example code taken from the CVS file "mod/gcl_japi.lsp" :

 

========================================================

(clines "#include <japi.h>")

 

;; BOOLEAN  
(defconstant J_TRUE  1)
(defconstant J_FALSE 0)

(defentry j_fileselect ( int string string string ) ( string "j_fileselect" ))
(defentry j_messagebox ( int string string ) ( int "j_messagebox" ))

========================================================

 

It is also possible to rebuild GCL linked to external libraries with the "compiler::link" function

 

These functions are described in the GCL documentation.

 

Cheers

 

Mike Thomas.
