Configuring the Software Environment - Debian (Ubuntu) Systems

Configuring the Software Environment - Debian (Ubuntu) Systems
Debian systems use the dpkg system to manage the software installed on the host. Wrapped around dpkg is another suite of tools called the Advanced Packing Tool (APT) that you can use to download packages from a central repository. These tools make it easy to install the packages you need for embedded development.

You can install packages with one command and test to see (using the -s switch) what happens by doing the following:

$ sudo apt-get -s install automake autoconf m4 gcc gdb dhcp3-server nfs-userserver
􀀁
tftpd minicom

This produces output like the following:

Some of these packages may already be installed on your system, and others may be out of date. In
some cases, the requested packages require other packages in order to work correctly. No worries—aptget
sorts all that out, figuring out what packages must be installed in what order. After installing the
packages, the system also runs any configuration scripts so the newly installed software is ready to run.

Running the command without –s produces output like the following:

$ sudo apt-get install automake autoconf m4 gcc gdb dhcp3-server nfs-user-server􀀁
tftpd minicom

autoconf is already the newest version.
m4 is already the newest version.
