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
