povray 3.7.0.RC7 does not support Preview_Start_Size

[Martin.vGagern@…]

It seems that povray 3.7.0.RC7 does not support the ​`Preview_Start_Size` init file setting.

debug.ini:

Width=800
Height=600
Output_File_Type=N
Preview_Start_Size=256
Input_File_Name=debug.pov

debug.pov:

#version 3.7;
camera { }

Callig povray debug.ini gives the following (or similar) output:

Are you sure this is not an upstream issue?

Replying to macsforever2000@…:

Are you sure this is not an upstream issue?

I'm not sure at all, no. I come from Gentoo, where policy is to report stuff at the distro level first and only upstream if distro maintainers say so. The issue does look specific to mac, and since upstream provides no usable binaries of povray for intel macs, I can't try with official binaries. On the other hand, I see nothing in the macports patches which looks like it might be responsible for this, so it probably isn't introduced by macports. I just ​reported this upstream as well, to the macintosh news group. I'm curious to see whether they will react.

It doesn't look like any replies to your message have appeared on the newsgroup.

I have updated the povray port to version 3.7.0.8 but on High Sierra it is still giving me a similar error:

Persistence of Vision(tm) Ray Tracer Version 3.7.0.8.unofficial (clang++ 4.2.1 @
 x86_64-apple-darwin17)
This is an unofficial version compiled by:
 MacPorts <https://www.macports.org/>
 The POV-Ray Team is not responsible for supporting this version.

Since I don't know anything about povray, other than what it is and how to build it, I would have to refer you back to the developers of povray for assistance in resolving this problem. Assertion failures usually indicate that there is a bug in the code, and only they know how to fix their code.
