* 本说明涉及软件有Mudos V22pre11源代码，bison for Win以及Vc++5.0以上 

使用软件: vc5以上，bison
将源码解压，进入~v22pre11/src目录
将windows目录下的所有.bat和.mak文件copy到上层目录中
用vc新建一个MUDOS WORKSPACE，选择Insert Project into Workspace…，将src下的edit_source.mak文件加入到workspace中，删除”source file”中的”local_options”文件，删除”make_func.tab.c”文件，执行step1.bat，得到make_func.c文件，把它加入到edit_source的project中
 

建立一个新文件，文件名为cc.h，文件内容如下：
#define COMPILER "cl"
#define OPTIMIZE "-G4"
#define CFLAGS "-DWIN32 -D_ALL_SOURCE -G4"
#define OBJDIR "obj"
在edit_source的project的setting项目里的”c/c++”->”preprocessor definitions”里去掉”DEBUG”参数，在”custom build”的”command”里添加如下命令：
cd E:\work\v22.pre11/src
.\windebug\edit_source -configure
.\windebug\edit_source -options -process grammar.y.pre -malloc -build_func_spec "cl /E " -build_efuns
“output”里添加”grammar.y” 
 
编辑edit_source.c，把” fprintf(yyout, "#define UINT32 unsigned long\n");”替换为:
{ //防止重复定义，WINDOWS把UINT32定义为unsigned int了
#ifndef WIN32
fprintf(yyout, "#define UINT32 unsigned long\n");
#else
;
#endif
}
编译edit_source，编译完成后会自动生成grammar.y文件
在dos下执行“bison grammar.y”，生成grammar.c
选择”project”->”insert project into workspace”，把Mudos.mak加入到mudos workspace中。修改mudos project，将setting->link->”object/library module”中的所有.lib文件删除，在”c/c++”->”preprocessor definites”中删除”DEBUG”,增加”MSDOS”参数。
修改backend.c，将static void call_heart_beat();替换成如下:
static void call_heart_beat()
{
object_t *ob;
heart_beat_t *curr_hb;
heart_beat_flag = 0;
#ifdef SIGALRM
signal(SIGALRM, sigalrm_handler);
#endif
#ifdef HAS_UALARM
ualarm(HEARTBEAT_INTERVAL, 0);
#else
# ifdef WIN32
# else
alarm(SYSV_HEARTBEAT_INTERVAL); /* defined in config.h */
# edif
#enndif
debug(256, ("."));
current_time = get_current_time();
current_interactive = 0;
if ((num_hb_to_do = num_hb_objs))
{
num_hb_calls++;
heart_beat_index = 0;
while (!heart_beat_flag)
{
ob = (curr_hb = &heart_beats[heart_beat_index])->ob;
DEBUG_CHECK(!(ob->flags & O_HEART_BEAT),
"Heartbeat not set in object on heartbeat list!");
DEBUG_CHECK(ob->flags & O_SWAPPED,
"Heartbeat in swapped object.\n");
/* is it time to do a heart beat ? */
curr_hb->heart_beat_ticks--;
if (ob->prog->heart_beat != -1)
{
if (curr_hb->heart_beat_ticks < 1)
{
curr_hb->heart_beat_ticks = curr_hb->time_to_heart_beat;
current_heart_beat = ob;
command_giver = ob;
#ifndef NO_SHADOWS
while (command_giver->shadowing)
command_giver = command_giver->shadowing;
#endif
#ifndef NO_ADD_ACTION
if (!(command_giver->flags & O_ENABLE_COMMANDS))
command_giver = 0;
#endif
#ifdef PACKAGE_MUDLIB_STATS
add_heart_beats(&ob->stats, 1);
#endif
eval_cost = max_cost;
/* this should be looked at ... */
call_function(ob->prog, ob->prog->heart_beat);
command_giver = 0;
current_object = 0;
}
}
if (++heart_beat
