Hello,

i’m hardly trying to create a legato app that uses CAN BUS.  
Actually i am trying to get the KillSwitch Demo running on mangOH Red.

But it seems that it can only run on mangOH green.

unfortunately its not compilable.

First error is in **KillSwitch/canOpen/Component.cdef** where the Base Path is missing:  
api:  
{

- 

```
   mangoh_muxCtrl.api

```

- 

```
   ${MANGOH_ROOT}/apps/MuxControl/mangoh_muxCtrl.api

```

}

And some othe rlittle things… but i am ending um with several errors:

mkapp -t wp77xx killSwitch.adef

you need to do this:

Developer studio-\> Project Properties \> C/C++ Build \> Settings-\> mkapp Tool -\> C build option -\> Additional compiler option

add “-Wno-error=unused-const-variable=”

Also in killSwitch.cpp, comment out  
// LE\_DEBUG(“Changing state: %d-\>%d”, this-\>\_state, State::DISABLED);  
// LE\_DEBUG(“Changing state: %d-\>%d”, this-\>\_state, State::OPERATING\_HOT);  
// LE\_DEBUG(“Changing state: %d-\>%d”, this-\>\_state, State::OPERATING\_NORMAL);
