GEGL filters for calling G'MIC in Win10/11. EXPERIMENTAL!

MareroQ · **Posted:** Wed Jan 28, 2026 2:10 am **(#1)**

Łukasz Grabski [activey, flatscrew] developed a generator that converts G'MIC filters to GEGL filters (fx).
Source code:
https://github.com/flatscrew/gmic-gegl-plugin

The generator is in preliminary version.
GMIC 3.6.5 generated 838 *.c files [but LinuxBeaver got 1121 files viewtopic.php?f=9&t=22038], of which 750 were compiled.
374 error-free Gegl filters were extracted (split into 9 packages).

These filters work for Gimp-2.10.38, 3.0.4 and RasterFlow.
With libintl-8.dll file fix it will work for Gimp-3.0.8/ 3.2 RC2
viewtopic.php?f=33&t=22057&p=300704#p300704

Instalation:

From the website:
https://gmic.eu/files/windows/
download: gmic_3.6.6_lib_win64.zip.
Unzip and copy the 5 files to the GIMP bin directory:

libc++.dll
libcgmic-3.dll
libfftw3_threads-3.dll
libfftw3-3.dll
libomp.dll

Unpack the 'gmic-gegl'.dll filter packages and install them locally (inside Gimp files):
For Gimp 2.10
c:\Program Files\GIMP 2\lib\gegl-0.4\gmic-gegl\

For RasterFlow
c:\Program Files\RasterFlow\lib\gegl-0.4\gmic-gegl\

List filter gmic-gegl:

SHOW SPOILER

Unfortunately, filters aren't (yet?) grouped into categories.
I recommend removing filters you'll never want to use.

Gmic non-destructive operations can also be achieved using the Run G'MIC command [gegl-gmic.dll]filter via copy-paste, so this is the most important filter with which you can replace filters that failed to compile.

Filters by category and without dependency on libintl-8.dll are posted in post #39.

Interesting, I had this since Dec 1st 2025 lol

It's true that I waited a long time to compile it for Windows because the author promised a quick release for Windows and Mac.
Unfortunately, and this worries me, the author has been inactive for a long time.

So after install you would just open G'MIC and select copy G'MIC command to get the run G'MIC command dialog?
BTW replacing the dll did indeed fix the GEGL plugins. All are working in Gimp-3.2 RC2.

Thanks!

The 'Run G'MIC command' should be invoked (launched) from the GIMP menu:

or from the search engine:

and paste the copied code here:

If the code works you can save it as 'Presets':

Someone needs to file a bug report here
https://gitlab.gnome.org/GNOME/gimp/-/issues

The main topic:

GEGL plugins on GIMP 3.0.6 and up require special compiling for Windows

Flatscrew's .exe of prebuilt GIMP dll works on Windows GIMP 3.0.6+
https://github.com/flatscrew/gmic-gegl-plugin

However when people try to compile the source code of his and Beaver's plugins manually, they do compile but the .dll does not work on Windows 3.0.6 +

On Linux the compiling works regardless of what you do and has no issue.

It appears that libintl-8.dll in C:\Program Files\GIMP 3\bin\ is the culprit, and that a hacky work around is swapping it with its older version, something I don't recommend. After all users should not be replacing critical .dll files

but the known proper working alternative is compiling the way Flatscrew does here. https://github.com/flatscrew/plugins-li ... -win64.exe but we don't know what Flatscrew is doing to compile and he has been absent for a month.

The goal is to figure out how to compile GEGL plugins that work on Windows GIMP 3.0.6+ without needing to "surgically" replace the libintl-8.dll file, or possibly get GIMP team to restore old compile GEGL plugin detection behavior. Once again Linux isn't affected at all by this issue, Just Windows 3.0.6+

- send this to GIMP team

Good luck reporting this, but even if it's diagnosed, it won't fix the problem in versions of GIMP already installed.

For those more curious: filters compiled by Flatscrew don't depend on the libintl-8 library (which made it easier to identify the cause of the problem).

I have no idea why this is happening, but the libintl-8.dll thread is closed for me.

Thanks!

But unfortunately i have no G'MIC menu item under the filters menu.
My GIMP program is in my USERAppData/local/programs/GIMP 2 folder. That is where i placed the dll files and the gmic-gegl folder.
gmic-gegl folder with the filters i placed in the gegl-04 folder.
The dll files i placed in the lib folder.

Are you talking about Gimp-2.10.38 now?

For this version, no additional Gimp filters are registered in the menu, nor is it possible to search for them.

This is the only way to select additional filters:

The only advantage of using these filters in Gimp-2.10 is perhaps slightly faster performance and direct preview, but the disadvantage is fewer layer manipulation options than the original G'MIC offers.
This plug-in was created for Gimp 3 to provide FX operations for GMIC (not available in Gimp-2.10).

I've never used/tested GIMP installed locally, but it should look like this

In directory USERAppData/local/programs/GIMP 2/bin:

libc++.dll
libcgmic-3.dll
libfftw3_threads-3.dll
libfftw3-3.dll
libomp.dll

In directory USERAppData/local/programs/GIMP 2/lib/gegl-0.4/gmic_gegl:

anisopatch.dll
anisotoon.dll
gegl-gmic.dll
gmic-array_random.dll
gmic-automixer.dll
gmic-bayer2rgb.dll
gmic-cartoon.dll
..... and so on

Yes Gimp-2.10.38 RC-1
That is exactly where i installed the files.

I am getting many gegl module not found errors at startup. Gimp is loading the linuxbeaver filters though.

There is no "Run G'MIC command" available. :hoh

MareroQ · **Posted:** Sat Jan 31, 2026 12:13 am **(#13)**

This looks like a problem with dll libraries (gmic-gegl has more dependencies on LinuxBeaver filters).

1. Can you verify that the 5 additional libraries in the GIMP bin directory have copied correctly?
2. Will clicking use_libcgmic.exe in the gmic-3.6.6-lib-win64 directory work (which will check compatibility with your Windows system):

I find it very unlikely that this is related to the way GIMP is installed (local or global), but I can't verify this.
If the results of steps 1 and 2 are OK, I can't solve this.

No, I have no interest in GIMP 2.10. I just have a question

Do these plugins from the .exe work on Windows 10-11 without needing to change the file libintl-8.dll
https://github.com/flatscrew/plugins-li ... -win64.exe

You said yes, once but I just want to confirm. That is all.

MareroQ · **Posted:** Sat Jan 31, 2026 8:46 am **(#15)**

Hi Contrast,

Why do you ask?
In Gimp 2.10.38 on Windows 10, the filters you compiled (about twice as many as those compiled with Flatscrew) work very well.
I've never tried this before and didn't say anything about it—which is good, because the ones compiled with Flatscrew don't work in Gimp 2.10, regardless of the libintl-8.dll version. I wrote (and I confirm for Win10)that they work in Gimp++ 3.0.4 (without modifying libint-8.dll).

Unlike you, Gimp-2.10.38 (and probably for some time yet) is my number one choice.

MareroQ · **Posted:** Sat Jan 31, 2026 9:32 am **(#16)**

You may have missed this, but the mystery remains why filters compiled by Flatscrew don't depend on libintl-8.dll.

Test for filter action-lines.dll.
Dependencies for filters compiled by You (and me):

Dependencies for filters compiled by Flatscrew:

Indeed after reinstalling the lib files in the bin folder voila!

Thanks MareroQ!

Still not able to get it to work in Rasterflow though. Also i am using the dev G'MIC version 3.6.7 in Gimp-2.10 and Gimp-3.2.0-RC2 +Git

Works fantastically well in Gimp-3.2.0-RC2 hey!

gasMask · **Posted:** Sat Jan 31, 2026 1:42 pm **(#19)**

MareroQ,
IDK c code hardly, but I suspect that Flatscrew has substituted one or more calls to the intel-lib with calls to a red exclamation marked library, such as 'runtime'.

This is nice. But if you put libcgmic-3.dll in the bin folder then BAtcher don't work. I test this.
