Hello

I've made my module and currently I have these errors :

requires compiler and library support for the ISO C++ 2011 standard. This
support is currently experimental, and must be enabled with the -std=c++11
or -std=gnu++11 compiler options.

make[2]: *** [module-gsoc-kshitij-goel.lo] Error 1

1. I have implemented it upon module-hid. It inherits FileDrive from
filedrv.h. I'm not able to understand what is meant by the following
variables in module-hid.cc :

integer m_nButtons;
std::vector<doublereal> m_lc_scale;
integer m_nLC;

These were being passed into FileDrive.

2. Basically, I have tried to implement Output stream : 77, taking Keyboard
as an input device.
