Introduction
------------
Welcome to emx 0.8h, a common environment for creating 32-bit programs
for OS/2 2.x and DOS. You can use the GNU C compiler to compile
programs for emx. The main design goal of emx is to simplify porting
Unix software to OS/2 2.x and DOS. Moreover, you can create `native'
OS/2 programs, including Presentation Manager applications.
The emx package includes:
- emx.dll, emxio.dll, emxwrap.dll and emxlibc.dll dynamic link
libraries for OS/2 2.x
- emx.exe DOS extender for running 32-bit programs under DOS
- emxbind.exe for creating .exe files which work both under OS/2 2.x
and DOS
- emxomf.exe for converting .o object files (a.out) to .obj object
files (OMF). With emxomf and LINK386 you can create OS/2 programs
that don't need emx.dll
- emximp.exe for creating import libraries
- emxexp.exe for creating a list of export definitions from object files
- C header files and a nearly complete C library with source
- a simple graphics library for 320x200 (256 colors) mode, with source
- a library for screen output in windows, with source
Additionally, the following GNU programs are available compiled and with
patches and sources (note that these files are not part of emx):
- GCC 2.5.7, the GNU C compiler (requires a 387 coprocessor under
MS-DOS!)
- GAS 1.38.1, the GNU assembler
- GDB 4.11, the GNU debugger
- ld, the GNU linker
- ar, nm, size, strip, objdump: some GNU utilities for dealing with
binary files
- texinfo, the GNU documentation system
- Patches for the GNU sources
- Patched source for GCC, GAS, GDB, ld, ar, nm, size, strip, objdump,
info, makeinfo, texindex. You can compile all these programs with
the files that come with emx (but you also need a make utility, such
as NMAKE).
- BSD curses library
You can get the complete GNU sources by anonymous ftp from
prep.ai.mit.edu and other archives, for instance ftp.uni-stuttgart.de.

Installing emx
--------------
For unpacking, you need unzip v5.0 which is available from many
archives. Look for files named
unzip50.exe MS-DOS executable for unzip
unz50_32.exe OS/2 2.x 32-bit executable
Read INSTALL.DOC to learn how to install emx.
After unpacking the emx runtime and development system packages,
you'll find further information in the following files:
\emx\doc\COPYING.EMX emx & library license
\emx\doc\COPYING GNU General Public License
\emx\doc\install.doc Installation guide
\emx\doc\emxrt.doc User's guide to the emx runtime package
\emx\doc\emxdev.doc Application developer's guide
\emx\doc\libref.doc C library reference
\emx\doc\build.doc Compiling the GNU sources
\emx\doc\history.doc Change log
\emx\doc\future.doc Things to do

\emx\book\emxdev.inf .inf version of emxdev.doc (optional)
\emx\book\libref.inf .inf version of libref.doc (optional)
After unpacking the GNU and BSD packages, you'll find further
information in the following files:
\emx\doc\COPYING GNU General Public License
\emx\doc\COPYING.LIB GNU Library General Public License
\emx\doc\COPYING.BSD BSD license (for libraries bsd and curses)

Where to get emx
----------------
emx is available for anonymous ftp on
ftp.uni-stuttgart.de [129.69.8.13]: /pub/systems/os2/emx-0.8h
ftp-os2.cdrom.com: [192.153.46.2]: /os2/2_x/unix/gnu/emx08h
src.doc.ic.ac.uk [146.169.2.1]: /pub/packages/os2/2_x/unix/gnu/emx08h
ftp.informatik.tu-muenchen.de [131.159.0.198]:
/pub/comp/os/os2/devtools/emx+gcc
Other files of interest
-----------------------
emx does not come with a `make' utility. I recommend dmake 3.8. It's
available for anonymous ftp on
ftp.uni-stuttgart.de [129.69.8.13]: /pub/systems/os2/programming/support/
ftp-os2.cdrom.com: [192.153.46.2]: /os2/all/program/
ftp.informatik.tu-muenchen.de [131.159.0.198]:
/pub/comp/os/os2/devtools/
Executables are in dmake38x.zip, source code is in dmake38s.zip.
dmake38.zip contains both dmake38s.zip and dmake38x.zip.
The emx graphics library currently supports only the 320x200 VGA mode.
Johannes Martin has created a graphics library for various SVGA cards.
It's available for anonymous ftp on
ftp.uni-stuttgart.de [129.69.8.13]: /pub/systems/os2/emx-0.8h/contrib/
ftp-os2.cdrom.com: [192.153.46.2]: /os2/2_x/unix/gnu/emx08h/contrib/
ftp.informatik.tu-muenchen.de [131.159.0.198]:
/pub/comp/os/os2/gnu/emx+gcc/contrib/
You need svgakt*.zip (or svgakit*.zip) and vesa*.zip (or
vesa_emx*.zip, * is the version number).
If you want to convert the texinfo files (GCC documentation, for
instance) to OS/2 on-line books (.inf files), I recommend Andreas
Kaiser's texi2ipf program:
ftp-os2.cdrom.com: [192.153.46.2]: /os2/2_x/unix/tex/txi2ipf1.zip
ftp.informatik.tu-muenchen.de [131.159.0.198]:
/pub/comp/os/os2/gnu/doc/txi2ipf1.zip
