Re: PixInsight 1.8.8-3 Released

[copello]

"sudo ./installer" it now says "Illegal instruction."

" indicates that your (virtual) CPU does not support SIMD extension SSE3.
What is the output of?

>cat /proc/cpuinfo

PixInsight requires if I am not mistaken, at least SSE3.

[Joe Cool]

Thank you copello. That's the problem.

Though my virtual processor is reported as my real processor, it does not pass all the flags correctly, so SSE3 does not show up.
Apparently VirtualBox can be re-compiled with the flags.

I'm looking into it now.

[Juan Conejero]

To be more precise, the FreeBSD, Linux and macOS versions of PixInsight 1.8.7 and 1.8.8 require a processor with SSE4.2 instruction support. See for example the official announcement of version 1.8.8.

Ah... No point in me trying further then. I haven't got SSE4.2. I can run any game on the planet with ultra settings on my ultrawide monitor with my hardware. I also run Adobe Photoshop, Premiere, After Effects, Maya, 3DS Max, Cinema 4D, Blender, Corel Painter, Solidworks, Kontakt, Cubase, Native Instruments, Ableton, FL Studio, Proteus Design Suite; All of these are a few examples of processor intensive software I use regularly, but I cannot run PixInsight on Linux, but I can on Windows 7. hmmm Weird.

Anyway, anyone who says Linux is a replacement for Windows is talking nonsense. A quick look on wine says the implementation of Photoshop CC 2019 or 2020 is rated "Garbage".
Adobe Premiere, also "Garbage".
Adobe After Effect, "Garbage".
Cinema 4D "Garbage".
Solidworks "Garbage".
I'm not going to bother looking further.

Linux, suspiciously not good.

Is there a way to run the latest version of Photoshop on Linux???
This is the de facto standard for most people for astro image processing.

And, is SSE4.2 absolutely necessary. How much of a performance boost is it?
