Hello,

I had a problem with Allegro Common Lisp version 4.3. I am trying to
call a Lisp function from a C program, and it prints the following error
message:

Error: loading library #p"/usr/students/schweiss/stage/my_lib.so"
       caused the following error:

       13365:/logiciels/licences/acl-4.3/bin/pb_clim2xm_composer.img:
rld:
Fatal Error: unresolvable symbol in
/usr/students/schweiss/stage/my_lib.so:
lisp_call

Thanks in advance.

lisp_call was removed from acl 4.3.  You might be
able to fake it with:

long lisp_call(int addr)
{
  void (*lc)(),*lisp_call_address();
  lc = lisp_call_address(addr);
  (*lc)();
}
