This removes the last warnings in this area; in this case changing endianess is not used for accessing emulated memory, just to flip few values to low endian for storage.

DOSBox uses the following libraries:
|
|
|
|
SDL 2.0
|
|
The Simple DirectMedia Layer available at https://www.libsdl.org/
|
|
SDL provides many essential cross-platform functionalities and
|
|
hardware accelerated rendering via OpenGL or Direct3D.
|

|
|
|
|
Opusfile, by Xiph
|
|
For compressed audio tracks (.opus) used with CDROM images.
|
|
Sources are available at https://opus-codec.org, however it is
|
|
also conveniently packages by all popular package managers for
|
|
Windows (MSYS2, MinGW, and Chocolatey), Linux (apt, dnf, zypper,
|
|
pacman), and OS X (Homebrew and MacPorts). Opus is today's
|
|
leading compression format and has replaced Vorbis as Ogg's
|
|
recommended lossy format. Is widely used in the largest audio and
|
|
video distribution platforms such as YouTube.

|
|
Curses (optional)
|
|
If you want to enable the debugger you need a curses library.
|
|
On Linux, install ncurses-devel via your distro package manager.
|
|
On macOS, install ncurses via brew or macports.
|
|
On Windows, install pdcurses at https://pdcurses.org/, or ncurses
|
|
via package-manager such as pacman within an MSYS2 environment.

If you want compile from developer sources (SVN) under a unix system, you will need:
|
|
- Subversion to checkout the sources, or gzip and tar to unpack them from archive
|
|
- GCC (>=4.8.1) or Clang (>=3.4)
|
|
- automake (>=1.6)
|
|
- autoconf (>=2.50)
|
|
- autoconf-archive (>=2009.x)
|
|
- make (>= 3.8)
|
|
- pkg-config (>= 0.25)
|
|
|
|
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.
