I didn't know Google Groups were still a thing. Have to check out some of the groups I used to visit.

Hi Lyle.
I'm surprised to learn that Mathmap does not work for You.
Do You have and what error messages?
As for me, Mathmap 1.3.5 (32bit Vista) works with any version of Samj 2.9 / 2.10.
In addition to files coming from the installation mathmap-1.3.5-setup.exe (mathmap.exe, libgsl.dll, libgslcblas.dll, libgtksourceview-2.0-0.dll - without libfftw3-3.dll because it already exists in the bin directory) I add missing: iconv.dll, intl.dll , libpng12-0.dll, libxml2.dll - and only for testers in the attachment.

MareroQ. Very interesting. What Windows version are you using and is it 64bit?

MathMap development was mostly done on Ubuntu which dropped 32bit for ever last year. Not many people could compile MathMap for Windows. Mark P and PhotoComix succeeded but that may not happen again.

It would be great to compile a 64bit MathMap under Windows. Here are some instructions from 2009.

Note it involves compiling Gegl, babl and Gimp first
Maybe things have changed and its easier now?

It's likely a paths issue as for as Mathmap and the portable GIMPs is concerned, Mario.

Hope someone takes up your challenge for Windows GIMP, Tas.
