patch itself

What is it?
===========

This is a patch against OCaml 3.02 sources useful for producing shared
libraries on i386 ELF systems.

How OCaml was changed?
======================

Added `-shared' option to ocamlopt native code compiler, telling
compiler to output shared object instead of executable. For summary
of changes see ChangeLog.

What is needed?
===============

OCaml 3.02 sources (and all the prerequisites), patch, CVS version of
GNU binutils (no earlier than 4 October 2001)

How to apply the patch?
=======================

Go to directory where OCaml 3.02 sources where installed and issue
following command `patch -p0 <[PATH_TO_PATCH/]1_shared.patch' where
PATH_TO_PATCH is directory where 1_shared.patch is located. Then
follow normal OCaml installation instructions.

How to use it?
==============

• get OCaml 3.02 sources
• apply patch
• follow installation instructions
• get and build CVS version binutils
• make sure gcc driver will use new ld
  • either by messing with GCC `spec' file
  • or [setenv|export] PATH=/path/to/new/ld:$PATH

ocamlopt -shared -o labltk.so -I +labltk labltk.cmxa -linkall
ocamlopt -o tkiface -I +labltk labltk.so.cmxa tkiface.ml \
         -cclib -Wl,-rpath,.,-lX11

Ways to get new ld (4 October 2001 and beyond):

• binutils CVS information
• binutils snapshots i havent tried them
• partially linked ld build with `gcc -s -o ld ld.partial.o'
• statically linked ld
