|
| 1 | +Things needed for compilation. |
| 2 | + |
| 3 | +SDL |
| 4 | + The Simple DirectMedia Library available at http://www.libsdl.org |
| 5 | + The dll distributed with the windows version of DOSBox is slightly |
| 6 | + modified. You can find the changes in the sourcepackage of DOSBox |
| 7 | + (src/platform/sdl-win32.diff). If you want the patched sourcetree |
| 8 | + send us an email. (see README) |
| 9 | + Licensed under LGPL |
| 10 | + Note that only version 1.2 and its subversions (1.2.8, 1.2.13 etc.) |
| 11 | + are currently supported. |
| 12 | + |
| 13 | +Curses (optional) |
| 14 | + If you want to enable the debugger you need a curses library. |
| 15 | + ncurses should be installed on just about every unix distro. |
| 16 | + For win32 get pdcurses at http://pdcurses.sourceforge.net |
| 17 | + License: Open source |
| 18 | + |
| 19 | +Libpng (optional) |
| 20 | + Needed for the screenshots. |
| 21 | + For win32 get libpng from http://gnuwin32.sourceforge.net/packages.html |
| 22 | + See http://www.libpng.org/pub/png/ for more details. |
| 23 | + License: Open Source |
| 24 | + |
| 25 | +Zlib (optional) |
| 26 | + Needed by libpng. |
| 27 | + For win32 get libz (rename to zlib) from http://gnuwin32.sourceforge.net/packages.html |
| 28 | + See http://www.zlib.net for more details. |
| 29 | + License: Open Source |
| 30 | + |
| 31 | +SDL_Net (optional) |
| 32 | + For modem/ipx support. Get it from http://www.libsdl.org/projects/SDL_net/ |
| 33 | + Licensed under LGPL |
| 34 | + |
| 35 | +SDL_Sound |
| 36 | + For compressed audio on diskimages. (optional) |
| 37 | + This is for cue/bin cdrom images with compressed (mp3/ogg) audio tracks. |
| 38 | + Get it from http://icculus.org/SDL_sound |
| 39 | + Licenced under LGPL |
| 40 | + |
| 41 | +ALSA_Headers |
| 42 | + (optional) |
| 43 | + for Alsa support under linux. Part of the linux kernel sources |
| 44 | + Licensed under LGPL |
| 45 | + |
| 46 | +If you want compile from the CVS under a unix system, you'll also need |
| 47 | +automake (>=1.6), autoconf(>=2.50). Should be available at http://www.gnu.org |
| 48 | + |
| 49 | +For building on unix systems. |
| 50 | +If you are building from the cvs run ./autogen.sh first before doing the following. |
| 51 | + |
| 52 | +1. ./configure |
| 53 | +2. make |
| 54 | + |
| 55 | +In step 1 you could add the following switches: |
| 56 | +--enable-debug |
| 57 | + enables the internal debugger. --enable-debug=heavy enables even more |
| 58 | + debug options. DOSBox should then be run from a xterm and when the sdl- |
| 59 | + window is active press alt-pause to enter the debugger. |
| 60 | + |
| 61 | +--enable-core-inline |
| 62 | + enables some memory increasing inlines. This greatly increases |
| 63 | + compiletime for maybe a increase in speed. |
| 64 | + |
| 65 | +--disable-fpu |
| 66 | + disables the emulated fpu. Although the fpu emulation code isn't |
| 67 | + finished and isn't entirely accurate it's advised to leave it on. |
| 68 | + |
| 69 | +--disable-fpu-x86 |
| 70 | + disables the assembly fpu core. Although relatively new the x86 fpu |
| 71 | + core has more accuracy then the regular fpu core. |
| 72 | + |
| 73 | +--disable-dynamic-x86 |
| 74 | + disables the dynamic x86 specific cpu core. Although it might be |
| 75 | + be a bit unstable, it can greatly improve the speed of dosbox on x86 |
| 76 | + hosts. |
| 77 | + Please note that this option on x86 will result in a different |
| 78 | + dynamic/recompiling cpu core being compiled then the default. |
| 79 | + For more information see the option --disable-dynrec |
| 80 | + |
| 81 | +--disable-dynrec |
| 82 | + disables the recompiling cpu core. Currently x86 and x86_64 only. |
| 83 | + You can activate this core on x86 by disabling the dynamic-x86 core. |
| 84 | + |
| 85 | +--disable-dynamic-core |
| 86 | + disables all dynamic cores. (same effect as |
| 87 | + --disable-dynamic-x86 --disable-dynrec) |
| 88 | + |
| 89 | +--disable-opengl |
| 90 | + disables OpenGL-support (output mode that can be selected in the |
| 91 | + DOSBox configuration file). |
| 92 | + |
| 93 | +--disable-unaligned-memory |
| 94 | + disables unaligned memory access. |
| 95 | + |
| 96 | +Check the src subdir for the binary. |
| 97 | + |
| 98 | +NOTE: If capslock and numlock appear to be broken. open |
| 99 | +src/ints/bios_keyboard.cpp and go to line 30 and read there how to fix it. |
| 100 | + |
| 101 | + |
| 102 | +Build instructions for VC++6 |
| 103 | +Don't use VC++ 6: it creates faulty code in core_normal.cpp |
| 104 | +Later Visual Studio versions work fine (vs2003/.net, vs2005, vs2008) |
