Lesson 11

Dates: 4/10/2014
Application compilation and installation on Linux
Linux for Engineering and IT Applications


Exercise: Debian/Ubuntu package building.


  • You should have the application files available in directory Project from the exercise with multiple Makefiles. Step into directory Project and re-compile the sources: 
    cd Project
make
  • Create directory tree BUILD/usr/local and copy the compiled files into it: 
    cd 
mkdir -p BUILD/usr/local
mkdir  BUILD/usr/local/bin
mkdir  BUILD/usr/local/lib
mkdir  BUILD/usr/local/include
cp Project/bin/app.x BUILD/usr/local/bin
cp Project/lib/libScalar_Product.a  BUILD/usr/local/lib
cp Project/include/Scalar_Product.h BUILD/usr/local/include
  • Create subdirectory DEBIAN 
    mkdir BUILD/DEBIAN
  • Check the size of the installation tree: 
    du -s BUILD/usr/local
  • Create file BUILD/DEBIAN/control with the following content: 
    Package: appx
Priority: optional
Section: application
Installed-Size: 32
Maintainer: Linux class
Architecture: amd64
Version: 1.0
Description: Scalar product of two vectors
  • Build package appx_1.0-0_amd64.deb: 
     
sudo -s
cd BUILD/
chown -R root:root usr/
dpkg -b . /tmp/appx_1.0-0_amd64.deb
  • Install the newly created package: 
    dpkg -i /tmp/appx_1.0-0_amd64.deb
  • Verify that the package has been installed: 
     
dpkg -l appx
