You might get the sliders back if you change to the system theme.



As with everything MS the operative word is might

I have given up on trying to install Mathmap to gimp 2.10.6. I have tried everything to get it to work and nothing works. What's confusing is the folders. How many MMInstall folders are there? That's probably why I can't get thing to work and the instructions are complicated as well. The folders within folders concept is making my head spin. If anyone knows an easier way to install Mathmap, please let me know.

Believe I just copy/pasted the plugins folder from my previous GIMP, Mackenzieh; don't recall doing so though which is weird (been working a lot and my braincells might not be there now; lol). Maybe the software gurus can help you. Maybe you can PM Graechan (believe that's where I got the 64-bit plugin from, but not sure anymore).

The installation in Windows Gimp 2.10.6 is not difficult although I am sure it will beat some

What not to use is an installer, install mathmap manually.

Gimp 2.10 now uses folders as containers for plug-ins, providing the folder has the same name as the plug-in. Follow that convention, any folder in the Gimp profile plug-ins is seen as the executable and adding to the folders paths is no longer required.

This has one snag with mathmap, it already uses a folder 'mathmap' and I can not zip two folders with the same name. So I have split the files into 2 zips.

mathmap-no-1.zip https://www.dropbox.com/s/bsw1aojjrdman ... 1.zip?dl=0 8.6 MB contains a folder mathmap holding mathmap.exe libfftw3-3.dll libgslcblas.dll libgsl.dll libgtksourceview-2.0-0.dll

Unzip and put the whole mathmap folder in C:\Users\your-name\AppData\Roaming\GIMP\2.10\plug-ins

mathmap-no-2.zip https://www.dropbox.com/s/k2y78lqvg7vls ... 2.zip?dl=0 140 KB contains the expressions files

Unzip and put the whole mathmap folder in C:\Users\your-name\AppData\Roaming\GIMP\2.10\

Does your version of Mathmap act flaky as far as the gui, Rich? I don't see the sliders for instance (and a few other issues). Still, the plugin works as expected, but I wish someone would address this idiocy.

I normally use mathmap in linux, (and even then using Gimp 2.8) just hoping that those Windows files might help some Windows users.

The sliders? Go back a couple of posts, it is the new Gimp 2.10 themes, the 'system' theme works here. Could be that one of the older Gimp 2.8 themes gives a result. In linux I am still using a theme from about 8 years ago

Indeed, I had to use System theme and the sliders came back. Light/Dark/Gray themes gives you the blank sliders (example of that). I hate the blow out white System theme though. lol

And you just ninja'd me.

Well, delved into my old 2.8x themes and found one acceptable to my palette. lolol

Thanks for the tip, Rich; Mathmaps fully usable again.

Thank you Richie2005. I will try it the way you explained it. Hopefully it will work. I'll let you know if I run into trouble.

I finally got Mathmap to work.

I installed the extra expressions and I keep getting error messages.

Why is that? What am I doing wrong?

Well, it turns out the Theme made GIMP unstable so had to go back to system. Does anyone know how to manually adjust colors of the system windows? Way too bright, but at least it's stable and I see my Mathmap sliders. lol

Someone really needs to find out why GIMP 2.8x themes cause 2.10x to get unstable. I'm just a clueless enduser.

I still have a few Mathmap presets that won't work myself, Meckenzieh, but to be honest, those same ones didn't work in GIMP 2.8x either. I just avoid using them. Droste and my custom preset are pretty much the only ones I use anyway.

I was really hoping to use them so, I will take your advice and won't use them. I've got bigger fish to fry. my laptop now has a 3rd bug and I hate it.

I found a simple solution for Windows 10 to show the sliders in the official themes.
Just add one old file to those listed by Rich2005 (plug-ins / matchmat / libgtk-win32-2.0-0.dll).
This unfortunately will not work for the portable 64bit version (but works e.g. for the 32bit version Samj Gimp 2.10.12 / 13)

Edit for Gimp 2.10.14
For Gimp 2.10.14_Win64 with support 32 bit and old plugins (from gimp.org) adding a file libgtk-win32-2.0-0.dll is not necessary (not recommended) - displaying is correct.

@Tas_Mania

I compiled Mathmat 1.3.5 with Gimp 2.10.14_Win10_64bit.
After the libnoise problem contained in
https://github.com/schani/mathmap



I compiled noise from:
https://github.com/eXpl0it3r/libnoise

Compilation completed without an error message.
However, the attempt to run in Gimp-2.10.15 fails (as in the screenshot)



Any hint where the error lies?

Hi MareroQ.
I've had that same error before.

I think it comes from GSL.
MathMap is looking for libgsl1X and libgsl2X is installed.
I was able to make a symbolic link on Linux
(sudo ln -s /usr/lib/x86_64-linux-gnu/libgsl.so.23 /usr/lib/x86_64-linux-gnu/libgsl.so.19)
You may not have GSL installed or it's the wrong version.

It's good you got this far with Windows 10. I've been thinking about using Azure which is a MSoft build system.
I'm right out of the Windows environment now and would struggle with it.

Hi Tas_Mania.

In my system libgsl is version 2.5 (libgsl-25.dll).
I tried to compile an older version of gsl-1.9 [20.02.2007] - but too many bugs and this is not for my completely amateur skills (I would have to rebuild the msys64 environment thoroughly).
The only hope is that the 1.3.5_32 bit version will work for a long time for 64 bit (personally I don't have any problems with this old version) or someone with experience (Samj? or Partha?) will try to compile it.

I had some hope that the problem lies only in the path of the temp file and its strange (for me)
format (* .c)

Thats because its written in C. Forward slashes in Windows are a problem but you must have resolved that.

Symbolic links can be made in Windows

You just have the new file on your system while the symbolic link provides the file required for compiling. This file is really only a pointer to the newer installed file.

Mark and PhotoComix are the only people who have compiled MathMap on Windows AFAIK and now PhotoComix is gone. Mark is a genius IMHO.
Nobody has ever used MathMap Composer on Windows. If you get it done click on the Composer Tab and see what I mean?
