Application

Deprecated: Previous, Cumbersome Method

**G'Mic git (v3.5.2)** for **GIMP 3.0.0-RC2** finally successfully built under **Kubuntu Noble 24.04**. It took jumping threw a few hoops, (using a few **Ubuntu Plucky** packages) so I'm posting the steps here for others.

1. IF you have GIMP 3.0 packages installed via the Ubuntuhandbook GIMP 3.0 PPA, UNINSTALL them and DISABLE/PURGE the PPA for now. Uninstall instructions are at the bottom of this page.
   Otherwise, you can skip this step.
   Reason: Unfortunately, gmic for GIMP 3.0 won't build using the dev packages from Panda Jim's Ubuntuhandbook PPA. I'm not sure what the problem is I had all necessary development packages installed but received a pkgconfig error:

$ qmake HOST=gimp
     Info: creating stash file /mnt/Data/Build/gmic-qt/.qmake.stash
     Project MESSAGE: GIMP major version is ............ 3
     Project MESSAGE: GMIC_PATH was not set: Found gmic sources in ../gmic/src
     Project MESSAGE: G'MIC repository was found (../gmic/src)
     Project MESSAGE: G'MIC version is ................. 352
     Project MESSAGE: CImg version is .................. 352
     Project MESSAGE: gmic_stdlib_community.h version is 352
     Project MESSAGE: Prerelease date is 25013108
     Project MESSAGE: Unix/X11 platform
     Project MESSAGE: Target host software is GIMP
     Project MESSAGE: OpenMP enabled, with g++
     Project MESSAGE: Release build
     Project ERROR: gimp-3.0 development package not found

2. We're going to need to use the latest pre-release packages from Ubuntu Plucky instead.
   Go here and DOWNLOAD the following Plucky debs to your hard drive:

libbabl-0.1-0_0.1.110-1_amd64.deb libbabl-dev_0.1.110-1_amd64.deb libgegl-0.4-0t64_0.4.52-1_amd64.deb libgegl-common_0.4.52-1_all.deb libgegl-dev_0.4.52-1_amd64.deb libgimp-3.0-0_3.0.0~RC2-1_amd64.deb libgimp-3.0-bin_3.0.0~RC2-1_amd64.deb libgimp-3.0-dev_3.0.0~RC2-1_amd64.deb libsharpyuv-dev_1.5.0-0.1_amd64.deb libsharpyuv0_1.5.0-0.1_amd64.deb libwebp-dev_1.5.0-0.1_amd64.deb libwebp7_1.5.0-0.1_amd64.deb libwebpdecoder3_1.5.0-0.1_amd64.deb libwebpdemux2_1.5.0-0.1_amd64.deb libwebpmux3_1.5.0-0.1_amd64.deb

3. Do a local INSTALL of all those debs you just downloaded.

4. BUILD GIMP 3.0.0-RC2 from Git:

git clone https://github.com/GreycLab/gmic.git
git clone https://github.com/GreycLab/gmic-qt.git
make -C gmic/src CImg.h gmic_stdlib_community.h
cd gmic-qt
qmake HOST=gimp
     Info: creating stash file /mnt/Data/Build/gmic-qt/.qmake.stash
     Project MESSAGE: GIMP major version is ............ 3
     Project MESSAGE: GMIC_PATH was not set: Found gmic sources in ../gmic/src
     Project MESSAGE: G'MIC repository was found (../gmic/src)
     Project MESSAGE: G'MIC version is ................. 352
     Project MESSAGE: CImg version is .................. 352
     Project MESSAGE: gmic_stdlib_community.h version is 352
     Project MESSAGE: Prerelease date is 25013109
     Project MESSAGE: Unix/X11 platform
     Project MESSAGE: Target host software is GIMP
     Project MESSAGE: OpenMP enabled, with g++
     Project MESSAGE: Release build
make -j$(nproc)

Yay, no more pkgconfig error! Assuming make finishes without error, you should now have a gmic_gimp_qt binary that works with GIMP 3.0.0-RC2.

5. We're done with the Plucky debs now. Let's DOWNGRADE them to the official Noble versions to avoid conflicts. These are the package versions to downgrade to as of today:

sudo apt install gir1.2-babl-0.1=1:0.1.108-1 gir1.2-gegl-0.4=1:0.4.48-2.4build2 libbabl-0.1-0=1:0.1.108-1 libbabl-dev=1:0.1.108-1 libgegl-0.4-0t64=1:0.4.48-2.4build2 libgegl-common=1:0.4.48-2.4build2 libgegl-dev=1:0.4.48-2.4build2 libsharpyuv-dev=1.3.2-0.4build3 libsharpyuv0=1.3.2-0.4build3 libwebp-dev=1.3.2-0.4build3 libwebp7=1.3.2-0.4build3 libwebpdecoder3=1.3.2-0.4build3 libwebpdemux2=1.3.2-0.4build3 libwebpmux3=1.3.2-0.4build3

6. We can now re-add the Ubuntuhandbook GIMP 3.0 PPA and re-install GIMP 3.0.0-RC2:

sudo add-apt-repository ppa:ubuntuhandbook1/gimp-3
sudo apt update
sudo apt install gimp libgegl-0.4-0t64

7. COPY your freshly built gmic_gimp_qt to /home/USER/.config/GIMP/3.0/plug-ins/gmic_gimp_qt/gmic_gimp_qt. You should now have a working G'Mic for GIMP 3 (ignore the localization messages).

gimp --verbose
     ...
     Querying plug-in: '/home/USER/.config/GIMP/3.0/plug-ins/gmic_gimp_qt/gmic_gimp_qt'
     [plug-in-gmic-qt] The catalog directory does not exist: /home/USER/.config/GIMP/3.0/plug-ins/gmic_gimp_qt/locale
     [plug-in-gmic-qt] Override method set_i18n() for the plug-in to customize or disable localization.
     [plug-in-gmic-qt] Localization disabled
     ...

Here's the built gmic_gimp_qt v3.5.2 binary for reference. It should certainly work if you're on Ubuntu Noble v24.04 or an equivalent Debian derivative.

It may also work on many other Linux distros.

I have tried to make it on Fedora (41) ... anyone can read how I made it to work with Gimp3 RC3 - support for gimp 3

Here's the version 3.5.3, built on Fedora 41
