现在想到的有两个办法，一个是 ugly hack，先对 building.py 打 patch：

```patch

+
+    # remove component dependencies required by the caller

 def MergeGroup(src_group, group):
     src_group['src'] = src_group['src'] + group['src']
     if group.has_key('CCFLAGS'):
```

然后在给 SConsctruct 打 patch：
```patch

+else:
+    objs = PrepareBuilding(env, RTT_ROOT, has_libcpu=False)

# build program
 env.Program(TARGET, objs)
```

这个对 RTGUI 是可以的，因为只有它依赖别的组件，没有其他组件依赖它。如果有其他组件依赖它的话就会有问题……

还有一个想到的方法，就是对每一个文件创建硬链接……

再来个干净的版本，这回应该没问题了～ 如果熊大觉得 OK 我 push 到 svn 里？ [s:160]
