Compile darktable on Ubuntu

This is a collection of scripts for compiling different versions of DarkTable on different versions of Ubuntu. The versions follows what I am using on my workstation :-)

There are 2 ways to install Darktable:

1. Darktable releases can be installed in a VM for trying it out.

   It is easy to build on your local machine, but trying out in a VM first is nice.

2. Follow Git Master on your computer using the script for that.

Dependencies

• KVM

  kvm must be installed in order for multipass to work Take a look here: https://www.tecmint.com/install-kvm-on-ubuntu/

• Multipass

  The scripts require Ubuntu Multipass to be installed, as all activity takes place within a virtual machine. You can of course create your own Ubuntu VM and fire off the "compile script" there.

  Multipass is a snap away on Ubuntu: snap install --classic multipass

• DT clone location

  DT is cloned to this location within the VM: /home/ubuntu/git/darktable

• Installation Darktable is installed into /opt/darktable within the VM.

What the scripts do:

The compile script does the following:

• creates/starts a VM called ubuntu-DTcompile
• clones Darktable from Github into the VM
• adds llvm repoes to the VM's APT sources
• adds llvm APT key into the VM
• installs loads of necessary Ubuntu packages in the VM
• builds and install Darktable in the VM
• starts Darktable to print the --version info in the VM

The end result from running "darktable --version" on the latest supported build, is:

darktable 4.8.0

How to compile Darktable 4.8.0 for Ubuntu 24.04 in a VM

    git clone https://github.com/per2jensen/dt-on-ubuntu.git
    cd dt-on-ubuntu/24.04/DT48
    chmod u+x install_in_vm.sh
    ./install_in_vm.sh

If you have an old VM lying around and want to start from a fresh, do this:

    multipass stop   ubuntu2404-DTcompile
    multipass delete ubuntu2404-DTcompile
    multipass purge 

Shell access to VM to see the buildlog

# become the 'ubuntu' user in the VM
multipass shell ubuntu2404-DTcompile  

# view the output captued from 'configure' and 'make'
less DT-4.8.0.log

Output from 'configure'

The full log file has been saved in git ("DT-4.8.0.log", for viewing if you are interested

Build on your machine

Once you are happy that things work in the VM, consider changing the compile script to your liking (set the INSTALL_PREFIX env variable in 22-04/DT42/DT42_compile.sh) and run the script to enjoy the DT goodness :-)

How to follow Git Master, to be on the bleeding edge

git clone https://github.com/per2jensen/dt-on-ubuntu.git
cd dt-on-ubuntu/24.04/DT48
chmod u+x master_compile.sh
./master_compile.sh

Edit the environment variables to your taste.
