regarding raspberry pi support package

sir, i have installed simulink support package for raspberry pi and also installed it sucessfully and able to write simple led blinkng program.......but when i access it from command window raspi function is shown unavailable and and after that even i install mplpkginstall file even after that raspi function is not available. my project is on fog removal system in which i hv to built independent hardware for fog removal system.... when i access camera using simulink it is showing me this error

The call to realtime_make_rtw_hook, during the after_make hook generated the following error:Description: tree

It appears that you may need to install the SDL development libraries; see http://www.libsdl.org/download-1.2.php or possibly "sudo aptitude install libsdl1.2-dev"

Once installed (and possibly you already have them) you may need to change your simulink configuration somehow to add an extra include directory that is the parent of where the SDL directory is installed, so that SDL/SDL.h would be a relative path to there. See http://www.mathworks.com/help/simulink/gui/simulation-target-pane-custom-code.html#bro3ioz-1

Walter and Surbhi Hello, the link is broken.

Can you give more details on how to solve it?

Thanks!

The link to libsdl 1.2 is still valid. The link to libsdl 2.0 is http://www.libsdl.org/download-2.0.php

Changing the include directories is described at https://www.mathworks.com/help/simulink/gui/include-directories.html
