Hi,

# Directory for writing build logs to
$log_dir=$ENV{HOME}."/Development/debian/sbuild_logs";

Change to suit where you wish log files to drop.

Regards

Phil

Phil Wyett has proposed the following checklist to package Gnuastro in Debian (and test before releasing the package; including the Reproducible building).

We should check this list on a new Debian operating system and hopefully merge it with the [existing checklist for packaging in Debian](https://git.savannah.gnu.org/cgit/gnuastro.git/tree/doc/release-checklist.txt) to have one reference for future builds.

// Start

sbuild setup
============

Install: sbuild-debian-developer-setup

I do not use apt caching, so I enter no when propmted for such things.

Comand: sudo adduser $USER sbuild

Reboot system.

Install: piuparts

Install: licenserecon

Create: ~/.sbuildrc and add below. Make sure to change '$maintainer_name='
and
'$uploader_name=' for your details.

# Name to use as override in .changes files for the Maintainer: field
# (mandatory, no default!).
$maintainer_name='Phil Wyett <philip.wyett@kathenas.org>';
$uploader_name = 'Phil Wyett <philip.wyett@kathenas.org>';

# Default distribution to build.
$distribution = "unstable";

# Default chroot (defaults to distribution[-arch][-sbuild])
$chroot = 'unstable-amd64-sbuild';

# Build arch-all by default.
$build_arch_all = 1;

$build_source = 1;

# --source-only-changes (applicable for dput. irrelevant for dgit push-
source).
$source_only_changes = 1;

# By default, the -s option only includes the .orig.tar.gz when needed
# (i.e. when the Debian revision is 0 or 1).  By setting this option
# to 1, the .orig.tar.gz will always be included when -s is used.
# This is equivalent to --force-orig-source.
$force_orig_source = 0;

# Verbose (-v)
$verbose = 1;

# Parallel build
$ENV{'DEB_BUILD_OPTIONS'} = 'parallel=4';

# Time to wait for a source dependency lock.  The default is 1 minute.
my $srcdep_lock_wait = 1; # 1 minute

$run_lintian = 1;
$lintian_opts = ['-v', '-i', '-I'];

$run_piuparts = 1;
$piuparts_opts = ['--schroot', '%r-%a-sbuild', '--no-eatmydata'];

$run_autopkgtest = 1;
$autopkgtest_root_args = '';
$autopkgtest_opts = [ '--', 'schroot', '%r-%a-sbuild' ];

# When to purge the build directory afterwards; possible values are "never",
# "successful", and "always".  "always" is the default. It can be helpful
# to preserve failing builds for debugging purposes.  Switch these comments
# if you want to preserve even successful builds, and then use
# "schroot -e --all-sessions" to clean them up manually.
$purge_build_directory = 'successful';
$purge_session = 'successful';
$purge_build_deps = 'successful';

# Directory for writing build logs to
$log_dir=$ENV{HOME}."/Development/debian/sbuild_logs";

# don't remove this, Perl needs it:
1;

Save and exit your editor.

Next we will create the 'unstable' build chroot.

Command: sudo sbuild-createchroot unstable /srv/chroot/unstable-amd64-sbuild

Building a package is a matter of creating the package and giving the '.dsc'
to 'sbuild'.

Example command: sbuild my_cool_app_1.0.0-1.dsc

Adding Reproducible building
============================

Install: reprotest

Now to run see command below.

Command: sudo reprotest --vary=-build_path,domain_host.use_sudo=1 --auto-
build my_cool_app_1.0.0-1.dsc -- schroot unstable-amd64-sbuild

// End
