1.将ucos_ii的源代码解压到c盘根目录下形成SOFTWARE文件夹（使用网上盛传的压缩文件SOFTWARE.RAR）
2.将bc45安装在c盘根目录下，形成bc45文件夹，从别的地方复制tasm.exe，编译asm文件用
3.建立一个工作文件夹比如叫c:workucos，然后将解压目录C:SOFTWAREuCOS-IISOURCE下的所有文件复制至该文件夹，有文件如下（不同版本文件可能不一样）：
OS_CORE.C，OS_FLAG.C，OS_MBOX.C，OS_MEM.C，OS_MUTEX.C
OS_Q.C，OS_SEM.C，OS_TASK.C，OS_TIME.C，uCOS_II.C，uCOS_II.H
解压目录下的C:SOFTWAREuCOS-IIEX1_x86LBC45WORK里的.h,.c,.asm文件拷贝到该文件夹，有文件如下：
INCLUDES.H，OS_CFG.H，OS_CPU.H，PC.H，UCOS_II.H
OS_CPU_C.C，PC.C，TEST.C，UCOS_II.C
OS_CPU_A.ASM
提示有文件重复，直接替换即可
4.修改c:workucos下include.h：
//＃i nclude "SOFTWAREucos-iiix86los_cpu.h"
//＃i nclude "os_cfg.h"
//＃i nclude "SOFTWAREblockspcsourcepc.h"
//＃i nclude "SOFTWAREucos-iisourceucos_ii.h"
＃i nclude "os_cpu.h"
＃i nclude "os_cfg.h"
＃i nclude "pc.h"
＃i nclude "ucos_ii.h"
去掉前面的路径，引用当前路径下的文件(本例中指路径c:workucos)
修改c:workucos下UCOS_II.C：
＃i nclude "softwareucos-iisourceos_core.c"
＃i nclude "softwareucos-iisourceos_flag.c"
＃i nclude "softwareucos-iisourceos_mbox.c"
＃i nclude "softwareucos-iisourceos_mem.c"
＃i nclude "softwareucos-iisourceos_mutex.c"
＃i nclude "s·oftwareucos-iisourceos_q.c"
＃i nclude "softwareucos-iisourceos_sem.c"
＃i nclude "softwareucos-iisourceos_task.c"
＃i nclude "softwareucos-iisourceos_time.c"
将softwareucos-iisource统统去掉，都引用当前路径下的文件(本例中指路径c:workucos)
5.在bc45环境下建立工程文件ide，选择dos模式
因为.h文件都在c:workucos文件夹下，需要设置一下include的路径(在bc45中选择菜单，optionsprojectDirectories，在窗口右边找到Include，增加路径，结果如下：c:bc45include;c:workucos)
6.在工程文件中添加c:workucos下的几个文件：
os_cpu_a.asm
os_cpu_c.c
pc.c
ucos_ii.c
test.c
7.编译运行，会出现很多警告，但可以生成exe文件
