[Ecls-list] Calling a function from C

[Steven_Kilby at kofax.com]

Hi,

Nevermind, I've figured it out.  I can call myp_hello directly.  I need to 
use the LISP symbol if I am going to call cl_funcall.

Thanks
Steven

[Ecls-list] Calling a function from C






Hi,

I have a file called hello.lsp with the following contents:

(in-package "MYP")
(proclaim '(si::c-export-fname hello))

(defun hello()
  '("A list with a string"))

In ecl I type the following:

(make-package "MYP" :use '("COMMON-LISP"))
(load "hello.lsp")
(compile-file "hello.lsp")

This produces a .fas file and should have an exported function name 
"myp_hello".

Then, from a C file I would like to do something similar to:

cl_safe_eval("(make-package "MYP" :use '(\"COMMON-LISP\"))");
cl_safe_eval("(load \"hello.fas\"));

cl_funcall(1, cl_intern(1, "myp_hello"));

The two calls to cl_safe_eval work as expected, but the call to cl_funcall 

fails.  Anyone have any ideas?

Thanks
Steven
