调网络不抓包，调I2C等时序不上逻辑分析仪，就像电工不用万用表！多用整理的好的文字，比截图更省流量，还能在整理过程中思考。

按提示把 rtconfig.py 中的

```
LFLAGS += ' --libpath ' + EXEC_PATH + '/ARM/RV31/LIB'
```

修改成

```
LFLAGS += ' --libpath ' + EXEC_PATH + '/ARM/ARMCC/LIB'
```

可以链接成功。

但按 building.py 中处理ARMCC那们自动替换却没起作用

```
            if rtconfig.EXEC_PATH.find('bin40') > 0:
                rtconfig.EXEC_PATH = rtconfig.EXEC_PATH.replace('bin40', 'armcc/bin')
                print rtconfig.LFLAGS ##替换前打印
                rtconfig.LFLAGS = rtconfig.LFLAGS.replace('RV31', 'armcc')
                print rtconfig.LFLAGS ##替换后打印

```

编译时的LOG如下

```
bspxxx>scons
scons: Reading SConscript files ...
##替换前打印
sct --libpath C:Keil_MDK_460/ARM/RV31/LIB
##替换后打印
