[digiKam-users] Couple questions about building digikam

[2895qgvg6v]

I'm not sure whether to send these questions to digikam-users or
digikam-devel, but since I've seen a few messages here suggesting that
some people build digiKam from source, I'll try here first.  If this
belongs in digikam-devel, please let me know.

I'm setting up a Linux (debian/testing) virtual machine in which to
build digiKam so I can experiment with it to learn a little bit about
how it works, and then try to contribute by fixing some bugs and/or
making some enhancements (e.g. solve the issues I described in
https://mail.kde.org/pipermail/digikam-users/2020-August/031169.html),
and I have a couple questions.

I tried "git clone https://invent.kde.org/graphics/digikam.git digikam"
on a partition with 1.3GB of free space and ran out of space.  How much
disk space is required to checkout the digiKam source code?
Also, how much additional space is required to compile, and is there a
difference in the space required when using bootstrap.local versus
bootstrap.linux?

I attempted to install all the dependencies did manage to run
bootstrap.linux, and it complained that I didn't have gettext, which
surprised me because Gettext is listed in the section "Dependencies To
Process Translations Files (optional)".  Is
https://www.digikam.org/api/index.html#externaldeps correct that Gettext
is optional, and if so what do I need to do get bootstrap.linux to
complete successfully without it installed (I looked at files shown in
the backtrace, but didn't see a clear way to avoid the check for Gettext)?

thanks for your help,
Peter

PS: FWIW, I'm close to retiring after a 40+ year system software
development career, so I'm hoping to soon have more time to contribute
to open source software projects that I find useful and interesting.

digiKam is a, open source project of 20 years old and require "2.6 GB Storage"
to checkout whole history, as it's  annotated on from og git web
interface of the project :

https://invent.kde.org/graphics/digikam

No difference. both bootstrap script require same local place to
compile. Only the target destination will be different.

Here i use the bootstrap.linux. All is compiled with debug symbols in
"build" directory:

Certainly gettext is a dependency for another component used by
digiKam. The list of dependencies is really long :

For Debian, a student starts to write a shell script to install
dependencies in one time. It's not complete :

https://invent.kde.org/graphics/digikam/-/blob/master/project/scripts/installdeps-ubuntu.sh

Mine for Mageia Linux is complete and here :

https://invent.kde.org/graphics/digikam/-/blob/master/project/scripts/installdeps-mageia.sh

Feel free to patch debian script and send me the diff for archiving to
git repository.

Best

Note: My Mageia dependencies script install more than required, as
kate editor, the requirement for static analyzers, the runtime
dependencies, the cross compiling dependencies for Windows, etc..
