Electronic whiteboard for Linux (ubuntu)

Dipin Krishna

How to convert our computer screen on to a digital electronic whiteboard, under Linux, could not be simpler. Only need a knob for Wii (Nintendo Console), an infrared emitter (such as a remote control), and the software for it (see the “Linux electronic whiteboard“).

Instructions for building WHITEBOARD from CPP branch

To check out the CPP branch of Linux Whiteboard -which the dependencies below mostly apply to- issue the following command:

svn checkout http://linux-whiteboard.googlecode.com/svn/branches/cpp/ linux-whiteboard-read-only

To build whiteboard, you’ll need the usual toolchain (gcc, g++ and make – these are available in the build-essential package) and the following libraries. The names of the libraries are taken from Ubuntu’s database. If you’re using a different Linux distro, please change them according to yours:

  • libtool
  • libcwiid1-dev
  • libgtkmm-2.4-dev
  • libglademm-2.4-dev
  • libxtst-dev
  • libcairomm-1.0-dev
  • libsigc++-2.0-dev
  • libgnome2-dev
  • intltool
  • libbluetooth-dev

If you have checked out whiteboard from our SVN repository, you probably need those too:

  • autoconf
  • automake

Having gotten those installed, navigate to the program’s root directory and issue the following commands:

./autogen.sh
make
sudo make install

 

For Ubuntu Gutsy Gibbon users, you need to add CXXFLAGS=”-DCOMPATIBILITY_GUTSY” to autogen.sh like this:

./autogen.sh CXXFLAGS=“-DCOMPATIBILITY_GUTSY”

 

To install to a different directory, so that you don’t need root permission when installing, add –prefix=

 
like this:
 
 ./autogen —prefix=~/whiteboard 
 
 
 
After ‘make install’, whiteboard will be installed to the directory ‘whiteboard’ in your home directory.
 
 
To build a Debian/Ubuntu package (for Ubuntu Hardy Heron only, one needs to modify the ‘debian’ directory to account for version differences in other distros):
 
     
  •  
       
    • Install fakeroot if you haven’t got it already.
      •  
    • Issue these commands:
      •  
     
    •  
 
 ./autogen.sh
 dpkg–buildpackage –us –uc –b –rfakeroot
