Introduction
|
|
============
|
|
|
|
GLUED (GNU/Linux Uniform Environment Distribution) is a minimal Linux
|
|
distribution targeted at embedded systems.
|
|
|
|
Configuration
|
|
=============
|
|
|
|
The first step to build GLUED for a particular system is to create a
|
|
configuration file. This configuration file contains details about the
|
|
system's architecture, packages that will be part of the distribution,
|
|
network configuration, etc.
|
|
|
|
To list all available systems issue the following command on a
|
|
terminal:
|
|
|
|
./mkconfig.bash list
|
|
|
|
Once you have identified the name of the system you want to build,
|
|
issue the following command, replacing \<system_name> with the name of
|
|
that system:
|
|
|
|
./mkconfig.bash \<system_name>
|
|
|
|
Building
|
|
========
|
|
|
|
After creating a configuration file, you are ready to compile all the
|
|
necessary packages.
|
|
|
|
To start the compilation process, issue the following command:
|
|
|
|
./mksystem.bash \<config_file>
|
|
|
|
Archives
|
|
========
|
|
|
|
After the system is compiled you can create archives for distributing,
|
|
developing or upgrading existing installations.
|
|
|
|
Toolchain Archive
|
|
-----------------
|
|
|
|
To create a package containing all the necessary tools to
|
|
cross-compile C/C++ programs for you target system, issue the
|
|
following command:
|
|
|
|
./pktoolchain.bash \<config_file>
|
|
|
|
Root Filesystem Archive
|
|
-----------------------
|
|
|
|
The root filesystem archive contains all files necessary to run a
|
|
GLUED system. It allows you to upgrade existing GLUED systems and
|
|
initialize storage devices. To create a root filesystem archive, issue
|
|
the following command:
|
|
|
|
./pkrootfs.bash \<config_file>
|
|
|
|
Initializing Storage Devices
|
|
============================
|
|
|
|
Initializing storage devices for GLUED involves:
|
|
|
|
* Partitioning the storage device
|
|
* Creating filesystems
|
|
* Populating filesystems
|
|
* Installing a bootloader if applicable
|
|
|
|
To perform all of the previous steps, you must first identify the
|
|
target block device file and then issue the following command (as
|
|
root):
|
|
|
|
./mkdisk.bash \<config_file> \<block_device>
|
|
|
|
Example
|
|
=======
|
|
|
|
Building GLUED for the system LAUV Seacon 1 and initializing a compact
|
|
flash card with the block device file /dev/sdd:
|
|
|
|
./mkconfig.bash lauv-seacon-1 &&
|
|
./mksystem.bash lctr-a6xx/lauv-seacon-1.bash &&
|
|
./pktoolchain.bash lctr-a6xx/lauv-seacon-1.bash &&
|
|
./pkrootfs.bash lctr-a6xx/lauv-seacon-1.bash &&
|
|
sudo ./mkdisk.bash lctr-a6xx/lauv-seacon-1.bash /dev/sdd
