10 # dllar - a tool to build both a .dll and an .a file
11 # from a set of object (.o) files for EMX/OS2.
12 #
13 # Written by Andrew Zabolotny, bit@freya.etu.ru
14 # Ported to Unix like shell by Stefan Neis, Stefan.Neis@t-online.de
15 #
16 # This script will accept a set of files on the command line.
17 # All the public symbols from the .o files will be exported into
18 # a .DEF file, then linker will be run (through gcc) against them to
19 # build a shared library consisting of all given .o files. All libraries
20 # (.a) will be first decompressed into component .o files then act as
21 # described above. You can optionally give a description (-d "description")
22 # which will be put into .DLL. To see the list of accepted options (as well
23 # as command-line format) simply run this program without options. The .DLL
24 # is built to be imported by name (there is no guarantee that new versions
25 # of the library you build will have same ordinals for same symbols).

42 # To successfuly run this program you will need:
43 # - Current drive should have LFN support (HPFS, ext2, network, etc)

45 # - gcc
46 # (used to build the .dll)
47 # - emxexp
48 # (used to create .def file from .o files)
49 # - emximp
50 # (used to create .a file from .def file)
51 # - GNU text utilites (cat, sort, uniq)
52 # used to process emxexp output
53 # - GNU file utilities (mv, rm)
54 # - GNU sed
55 # - lxlite (optional, see flag below)
