# dllar - a tool to build both a .dll and an .a file
# from a set of object (.o) files for EMX/OS2.
#
#  Written by Andrew Zabolotny, bit@freya.etu.ru
#  Ported to Unix like shell by Stefan Neis, Stefan.Neis@t-online.de
#
#  This script will accept a set of files on the command line.
#  All the public symbols from the .o files will be exported into
#  a .DEF file, then linker will be run (through gcc) against them to
#  build a shared library consisting of all given .o files. All libraries
#  (.a) will be first decompressed into component .o files then act as
#  described above. You can optionally give a description (-d "description")
#  which will be put into .DLL. To see the list of accepted options (as well
#  as command-line format) simply run this program without options. The .DLL
#  is built to be imported by name (there is no guarantee that new versions
#  of the library you build will have same ordinals for same symbols).
#
#  dllar is free software; you can redistribute it and/or modify
#  it under the terms of the GNU General Public License as published by

# To successfuly run this program you will need:
#  - Current drive should have LFN support (HPFS, ext2, network, etc)
#    (Sometimes dllar generates filenames which won't fit 8.3 scheme)
#  - gcc
#    (used to build the .dll)
#  - emxexp
#    (used to create .def file from .o files)
#  - emximp
#    (used to create .a file from .def file)
#  - GNU text utilites (cat, sort, uniq)
#    used to process emxexp output
#  - GNU file utilities (mv, rm)
#  - GNU sed
#  - lxlite (optional, see flag below)
#    (used for general .dll cleanup)

        dnl ****** IMPORTANT *******
        dnl   Unlike for the UNICODE setting, you can build your program in
        dnl   shared mode against a static build of wxWidgets. Thus we have the
        dnl   following option which allows these mixtures. E.g.
        dnl
        dnl      ./configure --disable-shared --with-wxshared
        dnl
        dnl   will build your library in static mode against the first available
        dnl   shared build of wxWidgets.
        dnl
        dnl   Note that's not possible to do the viceversa:
        dnl
        dnl      ./configure --enable-shared --without-wxshared
        dnl
        dnl   Doing so you would try to build your library in shared mode against a static
        dnl   build of wxWidgets. This is not possible (you would mix PIC and non PIC code) !
        dnl   A check for this combination of options is in WX_DETECT_STANDARD_OPTION_VALUES
        dnl   (where we know what 'auto' should be expanded to).
        dnl
        dnl   If you try to build something in ANSI mode against a UNICODE build
        dnl   of wxWidgets or in RELEASE mode against a DEBUG build of wxWidgets,
        dnl   then at best you'll get ton of linking errors !
