C) How to use the scripts
--------------------------
A) Environment preparation
--------------------------
0) Initial notes
- this guide has been prepared based on a clean debian testing netinstall system without any other DE.
It should work for other debian/ubuntu distros as well, but eventually you may run into small differences
here and there.
- you can change folder names below, as long as you update the "_config.sh" file accordingly.
1) Install following packages: bc, cdbs, git, pbuilder, rsync and required dependencies.
NOTE: sudo should already be installed. If not, install sudo as well.
2) Create a base folder for TDE, hereafter referred to as TDE_DIR (for example $HOME/tde_src)
3) Create the following folders [ see NOTE at point 0) about folder names ]
- in TDE_DIR: 0_logs : contains log files for repo update and global builds (more on this later)
1_git : contains the git repo clones and build hook scripts
2_build: folder used for build preparation and for local builds
3_repo : local repo for package installation (to be configured in /etc/apt/sources.list)
buildscripts: contains a local copy of the build scripts, which can be modified as required
- in TDE_DIR/1_git:
edeps : contains extra dependency modules necessary to build TDE (this folder is not necessary
is pre-built extra dependencies are used - see point 9 for more info)
hooks : contains build hook scripts to execute ad-hoc code before and after the building process.
Mainly used to apply patches automatically during the building process
4) Clone TDE git repositories
- TDE main repo
cd "TDE_DIR/1_git"
git clone https://mirror.git.trinitydesktop.org/gitea/TDE/tde
cd tde
git submodule init -- scripts
git submodule update -- scripts
./scripts/switch_all_submodules_to_head_and_clean anonymous
- TDE packaging repo
cd "TDE_DIR/1_git"
git clone https://mirror.git.trinitydesktop.org/gitea/TDE/tde-packaging
5) Add your user to the sudo group (not required if you are root)
su -c "adduser <username> sudo"
Logout and login again to make sure the new settings are applied.
* Optionally, consider extending your sudo timeout interval to avoid having to type your password too often
(this could be quite painful especially during long builds, which would not be able to complete if unattended).
To do this, type "sudo visudo" and then add "Defaults timestamp_timeout=<new timeout>", where the value is in
minutes. Use a value of -1 to set an infinite timeout.
6) Copy the files from "TDE_DIR/1_git/tde-packaging/debian/_buildscripts/local/additional_files" folder
to the respectivily named folders.
7) Create pbuilder base package with the command:
sudo pbuilder create
If you wish to build for a different distro or architecture, use the command:
sudo DISTRIBUTION=<target distro> ARCHITECTURE=<target architecture> pbuilder create
8) Setup the build scripts locally:
- copy build scripts from "TDE_DIR/1_git/tde-packaging/debian/_buildscripts/local" to "TDE_DIR/buildscripts"
and make sure all shell scripts are executable
- cd "TDE_DIR/buildscripts"
- cp ./internals/_config_template.sh _config.sh
- edit "_config.sh" to set your preferences and check that the various folder names match the structure on your disk.
Make sure to set the following variables:
* TDE_DIR to the correct path.
* DISTRO, DISTRO_NAME and ARCHITECTURE to match the distro and architecture you want to build for if different
from your current setup. Otherwise the variables can be left empty and auto detection will be performed.
* UPDATE_BRANCHES to the branches you want to keep updated from the main repositories.
* DEFAULT_REPO_BRANCH to the branch to check out at the end of the repositories update process.
9) Some additional packages (referred to as extra dependencies) are required to build and install TDE in debian/ubuntu.
These modules can be built locally, but the procedure is a bit cumbersome. Alternatively, Slavek Banko's
pre-built binaries can be used.
9.1) Using pre-built extra dependencies (recommended option)
- open "_config.sh" and set the variable USE_PREBUILD_EXTRA_DEPS to "y" (this is the default initial setting)
- add the following lines to the /etc/apt/sources.list file. This will setup Slavek's repositories in apt for
installing the extra dependency packages when TDE is installed.
* For R14.1.x series (repository branch "master")
# --- SLAVEK BANKO'S EXTRA DEPENDENCIES REPOSITORY ---
# - temporarily disabled -
# - http://mirror.ppa.trinitydesktop.org/trinity-testing/dists <YOUR DISTRO> deps
deb http://mirror.ppa.trinitydesktop.org/trinity-sb <YOUR DISTRO> deps-r14
* For R14.0.x series (repository branch "r14.0.x")
# --- SLAVEK BANKO'S EXTRA DEPENDENCIES REPOSITORY ---
deb http://mirror.ppa.trinitydesktop.org/trinity-sb <YOUR DISTRO> deps-r14
For example:
deb http://mirror.ppa.trinitydesktop.org/trinity-sb buster deps-r14
- install package dirmngr if required
- import Slavek's GPG key into your apt keyring
sudo apt-key adv --keyserver pool.sks-keyservers.net --recv-key A04BE668
9.2) Building extra dependencies locally
- open "_config.sh" and set the variable USE_PREBUILD_EXTRA_DEPS to "n"
- install the following packages: links2 and required dependencies.
- using links2 (or another browser), download the source code for the extra dependency modules from
Slavek's PPA (usually more recently updated):
https://quickbuild.pearsoncomputing.net/~slavek-banko/+archive/deps-r14/+packages
or from the official PPA:
https://quickbuild.pearsoncomputing.net/~trinity/+archive/trinity-nightly-build-dependencies/+packages
NOTES:
* Once the page open in your browser, select your distro in the combobox near the "Filter" button and click
the button to update. You should get a list of 10-15 modules, depending on the distro.
* Click on one module at a time, it will expand (or open another page) and show a list of .deb and other files.
* Save those files (exclude .deb files. Only .orig.tar.xz, .dsc, .debian.tar.xz are required) and store
them to TDE_DIR/1_git/edeps/<MODULE NAME> folder (one folder per module).
10) Add the following lines to the /etc/apt/sources.list file. This will setup your local repo in apt.
# --- LOCAL TDE REPOSITORY ---
deb [trusted=yes] file:TDE_DIR/3_repo <YOUR DISTRO> main
For example:
deb [trusted=yes] file:/home/tde_src/3_repo buster main
----------------------
B) Notes about scripts
----------------------
1) * Notes *
Modules are built using the build_module.sh script. After the build is completed, the installation .deb files are located in TDE_DIR/2_build/debs/<MODULE NAME>/ and the source code and build reports in TDE_DIR/2_build/debs/<MODULE NAME>/src/
The source code can be either the git repo or a local copy in TDE_DIR/2_build/build/<MODULE NAME>.
A module can be built in a clean chroot environment using pbuilder (default option) or locally using dpkg-buildpackage (useful for quick debugging/developing).
When using pbuilder, a hook can be used to invoke a shell when the build fails.
Build logs are automatically stored to files, but can also be displayed during the build process.
The default location of a module build log is TDE_DIR/2_build/debs/<MODULE NAME>/src/__build__.log
When building sets of modules or the whole TDE, a global build summary is automatically stored to TDE_DIR/0_logs/build_result.log to quickly check what built and what failed. It is recommended to delete that file before starting a new TDE build (if not, build results will be appended at the end of the file).
2) * Scripts description *
- scripts in 'internals' folder
Scripts used intenally by other scripts. No need for invoking these directly.
- update_git_repository.sh:
Script used to update the local clone of the git repositories.
It is possible to update multiple branches as specified by the variable UPDATE_BRANCHES in the configuration
file. After the update is completed, the local repositories will be switched to the branch specified by the
DEFAULT_REPO_BRANCH variable.
The script can also be used to switch the local repositories to a particular branch, without performing any update.
Usage:
update_git_repository.sh [options]
Options:
-i (Incremental) : in case the previous update was interrupted, continue from the last known updated module.
(useful on slow/unstable internet connections). If the previous update had completed,
this option is ignored.
-v (Verbose) : display and log more output. Useful for troubleshooting.
-ub "<branches>" (Update Branches) : allows to specify the branches to update. This override the variable
UPDATE_BRANCHES in the configuration file. If a single branch is specified and the
'-db'/'-sb' paraemters are not used, '-ub' can be used to update and switch a single branch.
-db <branch> (Default Branch) : allows to specify the default branch. This override the variable
DEFAULT_REPO_BRANCH in the configuration file.
This option is only used if the argument '-so' is not specified.
-so <branch> (Switch Only) : switch the local repositories to the specified branch, without doing any update.
If '-ub' is used, the '-so' branch name must be one of those specified in the 'ub' branches.
- build_module.sh
Build a single module.
Usage:
build_module.sh [options] module_name
Options:
-g (Git) : build from git repo sources. If missing, build from the local copy in build folder.
-l (Local) : build the module locally. If missing, build in a clean chroot environment
-sl (Show Log) : output the building logs to terminal while the build is ongoing
-lr (Log Result) : log (append) build result (OK, FAILED) to TDE_DIR/0_logs/build_result.log file
-sh (Shell Hook) : use a shell hook for failing builds, only valid if building using pbuilder (clean chroot environment)
-po (Prepare Only): only prepare the source folder but do not build the module. Useful to prepare the source code before
doing local changes/development. The module can then be built from the modified local folder
-d (Debug) : enable debug symbols if possible (debian/rules file must contain "RelWithDebInfo" for this to work)
-ip (Internal Pbuilder): build using internal pbuilder mode (experimental)
- <dd>_<set_name>.sh
A number of scripts used to build sets of modules. Each script builds an individual set.
Modules are built from the git sources and the build result is automatically appended to
TDE_DIR/0_logs/build_result.log.
Usage:
<dd>_<set_name>.sh [options] set_name
Options:
-s N: if specified, skip first N modules from the set of modules
The sets are logically grouped as "base system", "applications" and "others"
00_extradeps.sh : extra dependencies modules
01_base_01.sh - 03_base_03.sh : TDE base system
04_application_01.sh - 09_application_06.sh : application modules
10_others_01.sh - 11_others_02.sh : other modules that are somehow less used
91_build_base.sh : whole TDE base system in 00_extradeps.sh - 03_base_03.sh
92_build_applications.sh : all TDE applications in 04_application_01.sh - 09_application_06.sh
93_build_others.sh : all modules in 10_others_01.sh - 11_others_02.sh
- 99_build_TDE.sh
Script used to build the complete TDE at once. Calls the dd_setname.sh set scripts in order.
Usage:
build_TDE.sh
- create_repo.sh
Creates a local repository from the .deb files currently stored in TDE_DIR/2_build/debs.
Usage:
[sudo] create_repo.sh [options]
Options:
-b (Backup) : create a backup of the existing repository in TDE_DIR/CFG_REPO_DIR.backup
3) * Building hooks *
Hooks are available to execute ad-hoc code before and after the build process. For example this is very useful to automatically apply patches.
There are two type of hooks:
- pre_build : applied before switching the module to quilt format and build
- post_build: applied after the build (dpkg-buildpackage or pbuilder) has terminated
To use a hook, create an executable script (pre_build.sh and/or post_build.sh) in the TDE_DIR/1_git/hooks/<MODULE NAME> folder. The scripts are executed in the build_module.sh environment, so have access to all the variables defined in that file. See the files in the "hook examples" folder for real usage samples.
-------------------------
C) How to use the scripts
-------------------------
1) Follow the steps in section "A) Environment preparation" (only required the first time).
2) cd "TDE_DIR/buildscripts"
3) Update to latest git repository using
./update_repositories.sh
4) Run "sudo pbuilder update" at the beginning of the day to update the base package to the latest version. This will speed up
the process when building several modules in sequence.
5) Build modules as per your needs. You don't need to use "sudo" directly since the scripts will do that automatically if
required. Just type your sudo password when prompted to do so.
6) Create a local repository from the packages you have just built, to be used as installation repository.
[sudo] ./create_repo.sh
7) Install TDE as you usually do. For example as follow:
- sudo apt-get update
- sudo aptitude install tdebase-trinity (for a minimalistic TDE environment)
or
sudo aptitude install tde-trinity (for a standard TDE environment)
Examples of real usage:
1) build a single module
- ./build_module.sh -g -sl "dependencies/libr" -> build libr package. This is a good test to check
whether everything is working fine
- ./build_module.sh -g "tdelibs" -> build "tdelibs" from git sources in a clean chroot environment
- ./build_module.sh -g -l -sl "applications/amarok" -> build "amarok" locally from git sources and
display building logs during building
- ./build_module.sh -sh -lr "tdebase" -> build "tdebase" from the local sources (in TDE_DIR/2_build/build/tdebase)
in a clean chroot environment and launch a shell in case of building failure.
Append the build result (OK, FAILED) to TDE_DIR/scripts/logs/build_result.log
- ./build_module.sh -g -po "tdelibs" -> prepare "tdelibs" for building from git sources. Source code will be available
in TDE_DIR/2_build/build/tdelibs. After you have made changes to the source and
want to build the modified package, run './build_module.sh "tdelibs"'
2) build a single set
(optional) delete the TDE_DIR/0_logs/build_result.log file
./01_base_01.sh -> build this set.
./03_base_03.sh -s 3 -> build this set but skip the first 3 modules of the set.
3) build all TDE
./99_build_TDE.sh -> build all TDE
4) [sudo] ./create_repo.sh -> build or update your local TDE repository
