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 5.0.0

How to compile Darktable 5.0.0 for Ubuntu 24.04 in a VM

    git clone https://github.com/per2jensen/dt-on-ubuntu.git
    cd dt-on-ubuntu/24.04/DT50
    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-5.0.0.log

Output from 'configure'

The full log file has been saved in git ("DT-5.0.0.log", for viewing if you are interested

Build on your machine

Once you are happy that things work in the VM, consider changing a couple of env vars:

• set the DT_SRC_FOLDER env variable in 24-04/DT50/DTcompile.sh
• set the INSTALL_PREFIX env var in 24-04-DT50/envvars

and run the DTcompile.sh 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.
