[solved]GnoFract 4d - error

If you would like to extract interesting pictures made by math/fractals like famous Mandelbrot you can try this util.

Unfortunately sometimes this throws segmentation fault, but since I've updated the system, it cannot start. (gnofract4d-4.3-1.mga8)
The current error:
Code: Select all

I've downloaded the current source from their website, and built it. That works well... So this is the solution...

Oh, partly my fault :-) Sorry.

I've tried the new version because the segmentation fault, and it save new config file, so If I delete .gnofrac4d file from user folder, de orig gnofract4d-4.3-1.mga8 works.
But I suggest to compile the source to stop segmentation faults

We already have the latest version 4.3 https://github.com/fract4d/gnofract4d/releases

But there seems to be already a (open) bugreport upstream about this. It's related to Python https://github.com/fract4d/gnofract4d/issues/164

Yeah, I saw that the same version, but the rebuilt not installed version works well from the soure's folder.

No other error just segmentation fault after some clicks (zooming in img), fastest to get using explorer mode on.

I have removed mageia package: gnofract4d-4.3-1.mga8.x86_64

I built the source with
Code: Select all
setup.py build

Then with bin/build.sh :-)

and installed it with
Code: Select all
setup.py install


and the new version not worked well, because of different folders setup. I haven't found yet where to change at source, but I've made a symlink to share folder it wanted and now works well...

(the bin file is in different folder, but I think it installed everything else to the same place than mga package, only share folder place have to configure somewhere)
