Things needed for compilation.

SDL
The Simple DirectMedia Library available at http://www.libsdl.org
The dll distributed with the windows version of DOSBox is slightly
modified. You can find the changes in the sourcepackage of DOSBox
(src/platform/sdl-win32.diff). If you want the patched sourcetree
send us an email. (see README)
Licensed under LGPL
Note that only version 1.2 and its subversions (1.2.8, 1.2.13 etc.)
are currently supported.

Curses (optional)
If you want to enable the debugger you need a curses library.
ncurses should be installed on just about every unix distro.
For win32 get pdcurses at http://pdcurses.sourceforge.net
License: Open source

Libpng (optional)
Needed for the screenshots.
For win32 get libpng from http://gnuwin32.sourceforge.net/packages.html
See http://www.libpng.org/pub/png/ for more details.
License: Open Source

Zlib (optional)
Needed by libpng.
For win32 get libz (rename to zlib) from http://gnuwin32.sourceforge.net/packages.html
See http://www.zlib.net for more details.
License: Open Source

SDL_Net (optional)
For modem/ipx support. Get it from http://www.libsdl.org/projects/SDL_net/
Licensed under LGPL

SDL_Sound
For compressed audio on diskimages. (optional)
This is for cue/bin cdrom images with compressed (mp3/ogg) audio tracks.
Get it from http://icculus.org/SDL_sound
Licenced under LGPL

ALSA_Headers
(optional)
for Alsa support under linux. Part of the linux kernel sources
Licensed under LGPL

If you want compile from the CVS under a unix system, you'll also need
automake (>=1.6), autoconf(>=2.50). Should be available at http://www.gnu.org

For building on unix systems.
If you are building from the cvs run ./autogen.sh first before doing the following.

1. ./configure
2. make

In step 1 you could add the following switches:
--enable-debug
enables the internal debugger. --enable-debug=heavy enables even more
debug options. DOSBox should then be run from a xterm and when the sdl-
window is active press alt-pause to enter the debugger.

--enable-core-inline
enables some memory increasing inlines. This greatly increases
compiletime for maybe a increase in speed.

--disable-fpu
disables the emulated fpu. Although the fpu emulation code isn't
finished and isn't entirely accurate it's advised to leave it on.

--disable-fpu-x86
disables the assembly fpu core. Although relatively new the x86 fpu
core has more accuracy then the regular fpu core.

--disable-dynamic-x86
disables the dynamic x86 specific cpu core. Although it might be
be a bit unstable, it can greatly improve the speed of dosbox on x86
hosts.
Please note that this option on x86 will result in a different
dynamic/recompiling cpu core being compiled then the default.
For more information see the option --disable-dynrec

--disable-dynrec
disables the recompiling cpu core. Currently x86 and x86_64 only.
You can activate this core on x86 by disabling the dynamic-x86 core.

--disable-dynamic-core
disables all dynamic cores. (same effect as
--disable-dynamic-x86 --disable-dynrec)

--disable-opengl
disables OpenGL-support (output mode that can be selected in the
DOSBox configuration file).

--disable-unaligned-memory
disables unaligned memory access.

Check the src subdir for the binary.

NOTE: If capslock and numlock appear to be broken. open
src/ints/bios_keyboard.cpp and go to line 30 and read there how to fix it.


Build instructions for VC++6
Don't use VC++ 6: it creates faulty code in core_normal.cpp
Later Visual Studio versions work fine (vs2003/.net, vs2005, vs2008)
