Passing a parameter to a ROS Timer callback

I'm trying to pass a parameter to a ROS Timer callback using boost bind as I'd have done it for a subscriber callback but it's not working for me.

Here's the relevant part of the code.

    int my_arg = 0;
                     boost::bind(&MyClass::callback, this, _1, _2, my_arg),
                     true); //for oneshot

void MyClass::callback(int arg)
    ROS_ERROR_STREAM("callback: " << arg);

But this is not compiling:

/usr/include/boost/bind/bind.hpp:69:37: error: ‘void (MyClass::*)(int)’ is not a class, struct, or union type

Any idea?

The bind call should match the function signature. You'll have to remove the _1, _2 part from the bind call.
