The thing is obviously dynamically linked and on the host we have none of those dependencies. Let’s run it: hostmachine$ bin/darktableīin/darktable: error while loading shared libraries: libdarktable.so: cannot open shared object file: No such file or directoryĪh. (note: substitute your own container id, it’s the big number in the command prompt from inside the container, or find it with “docker container ps”) hostmachine$ docker cp 77d58544b6e4:/opt/darktable/bin. You’d have to start over with the build process. Note: DO NOT EXIT the container! If you’re not familiar with Docker, that container and everything in it pretty much disappears when you exit it. Now we finally get to the crux of the problem, namely that I want to copy that sucker out of the docker container and use it on my host machine. rwxr-xr-x 1 root root 49792 Jan 22 18:40 darktable-generate-cache rwxr-xr-x 1 root root 52816 Jan 22 18:40 darktable-cmstest rwxr-xr-x 1 root root 36328 Jan 22 18:40 darktable-cltest rwxr-xr-x 1 root root 97704 Jan 22 18:40 darktable-cli rwxr-xr-x 1 root root 466376 Jan 22 18:40 darktable-chart rwxr-xr-x 1 root root 25056 Jan 22 18:40 darktable Now, witness with amazement the built binary of darktable: ls -la /opt/darktable/binĭrwxr-xr-x 2 root root 4096 Jan 22 18:40. Right so we do what the build script kindly asks us to: cmake -build "/github/darktable/build" -target install -j8 $ cmake -build "/github/darktable/build" -target install -j8 To actually install darktable you need to type: Lots of output truncated here for brevity, but you will see something like this at the end: Linking CXX shared module libdemosaic.so Now go grab yourself a cup of coffee, this will take a while. build.sh -prefix /opt/darktable -build-type Release We do it the easy way, as per the instructions on GitHub - darktable-org/darktable: darktable is an open source photography workflow application and raw. (tons of cd git submodule init & git submodule updateįinally we’re ready to build. $ docker run -it apt update & apt install build-essential I execute the following interactively but you could of course stuff all this into the Dockerfile if you wanted. Right so now we have an image which is almost suitable for a build. You can also name the image but for this purpose we don’t care what the image is called. $ docker build - 7fb36dc89c21 2 hours ago 2.05GBĬopy the image id, you’ll need it for later. GitHub and grab the Dockerfile from there.All you need is to install docker on your local machine (sudo apt install docker.io I think on Ubuntu). Fortunately the developers were sensible enough to use docker to setup the Travis CI build environment and we can help ourselves to the Dockerfile they use for that. Yes and there are SO many dependencies to have in place before you even think of starting a build. I guess that doesn’t make a lot of sense so let me explain how I build darktable, in case anyone else feels up to the challenge. The problem is that the final executable is dynamically linked and contains references to dependencies I don’t have. Actually to the point of getting a success return code out of cmake and a finished binary. So I went my own way and managed to get a good part of the work done. There are no instructions that work out of the box. Trust me when I say I visited ALL the links you can find on Google about this. This has turned out to be bit more of a challenge than I expected, not least because what little documentation exists on this subject is either grossly inadequate or out of date or both. The bleak LUT from above.I’m on a mission to try and build darktable from source. So I spent a few minutes fixing it up ( ) and now you can easily get nice plots from LUTs: Not work with Python3 or recent verions of PyOpenColorIO. Unfortunately the code is not maintained and does When I was looking for tools to convert LUT formats, I came acrossĪnd PlotThatLUT, which provide a nice way of visualizing the The great thing about LUTs is that they allow you to quickly apply a style to More resources are linked from the Darktable blog post on The module supports loading andĪpplying 3D LUTs (Look Up Tables) that come as Cube or Haldclut files.Īpparently LUTs are quite commonly used in the film industry, which means thereĪre quite a few sites out there where people share their LUTs. Darktable added a lut3d module a while ago.
