+Things needed for compilation:
+
+SDL
+    The Simple DirectMedia Library available at https://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)
+    Note that only version 1.2 and its subversions (1.2.8, 1.2.13 etc.)
+    are currently supported.
+    License: LGPLv2+
+
+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 https://pdcurses.org/
+    License: Public Domain
+
+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: zlib/libpng
+
+Zlib (optional)
+    Needed by libpng.
+    For win32 get libz (rename to zlib) from http://gnuwin32.sourceforge.net/packages.html
+    See https://www.zlib.net/ for more details.
+    License: zlib
+
+SDL_Net (optional)
+    For modem/ipx support.
+    Get it from https://www.libsdl.org/projects/SDL_net/release-1.2.html
+    License: LGPLv2+
+
+SDL_Sound (optional)
+    For compressed audio on diskimages (cue sheets) support.
+    This is for cue/bin cdrom images with compressed (mp3/ogg) audio tracks.
+    Get it from http://icculus.org/SDL_sound
+    Licence: LGPLv2+
+
+ALSA_Headers (optional)
+    for Alsa support under linux. Part of the linux kernel sources
+    License: LGPLv2+
+
+If you want compile from developer sources (SVN) under a unix system, you'll
+also need automake (>=1.6) and autoconf(>=2.50).
+Should be available at https://www.gnu.org/software/
+
+For building on unix systems.
+If you are building from developer sources run ./autogen.sh first before doing
+the following:
+
+    $ ./configure
+    $ make
+
+You can also run "./configure --help" for extra features to enable/disable.
+Some of them are:
+
+--enable-debug
+        enables the internal debugger. --enable-debug=heavy enables even more
+        debug options. To use the debugger, DOSBox should be run from an xterm
+        and when the sdl-window is active press alt-pause to enter the
+        debugger.
+
+--disable-core-inline
+        disables some memory increasing inlines. This speeds up compilation,
+        but may result in a slower dosbox.
+
+--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
+--disable-fpu-x64
+        disables the assembly fpu core. Although relatively new, the x86/x64
+        fpu core has more accuracy than the regular fpu core.
+
+--disable-dynamic-x86
+        disables the dynamic x86/x64 specific cpu core. Although it might be
+        a bit unstable, it can greatly improve the speed of dosbox on x86 and
+        x64 hosts.
+        Please note that this option on x86/x64 will result in a different
+        dynamic/recompiling cpu core being compiled than the default.
+        For more information see the option --disable-dynrec
+
+--disable-dynrec
+        disables the recompiling cpu core. Currently x86/x64 and arm only.
+        You can activate this core on x86/x64 by disabling the dynamic-x86
+        core.
+
+--disable-dynamic-core
+        disables all dynamic cores (same effect as --disable-dynamic-x86
+        or --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 up to vs2010)
