AVX2 disabled on Windows as workaround for gcc bug

[sbabic44]

On Keysight 3000T, software throws shader error and quits.
PC is Windows, Intel 4600 HD, OpenGL 4.3. latest driver..
Errors in att..

Error 450.txt

Tried changing GLSL version: 450 to 430

Error 430.txt

Looks like the 4600 HD doesn't support 64-bit integer arithmetic (GL_ARB_gpu_shader_int64). Do you have a machine with a discrete graphics card you can try?

Intel integrated cards have been lagging in support for a while, but even fairly old NVidia/AMD discrete GPUs should work.

Yes, I'm afraid I will need to upgrade..
Will try on laptop it has Nvidia..
And that was freaky fast answer, respect !!
Anyways, I'll try and report back..
Reagrds,

Yes, that was that, i managed to start it, Now I get other error:
GetConsoleScreenBufferInfo() failed (6);
When I try to start hystogram or FFT or any graphical analysis.
Statistics and text measurements work fine.

This is on Windows, I assume? Can you post a screenshot of the error showing both the glscopeclient window and the console?

I confirm on my side glscopeclient "crash" with FFT too with Windows build it seems related to alignment to be confirmed...
https://github.com/anthonix/ffts is used in glscopeclient and is known to have some https://github.com/anthonix/ffts/issues in fact and seems dead (not maintained) since few years, latest commit was on Jun 17, 2017.
So far I was searching an alternative but it is not easy to find something good fast/multi-platform with open license like MIT or BSD license...
For information the https://github.com/linkotec/ffts fork which is more recent does not build correctly with MSYS2 mingw64 ...

Yes it crashes with Segmentation fault:

sinisa@t440p MINGW64 ~
$ glscopeclient scoop:agilent:lan:3104t.:5025
GetConsoleScreenBufferInfo() failed (6);
Warning: glscopeclient works best with the OMP_WAIT_POLICY environment variable
set to PASSIVE
Segmentation fault

sinisa@t440p MINGW64 ~

Main screen closes, nothing to see there.

I tried FFT, histograms, and few more and it crashes.

This issue shall be probably renamed as it is an issue with FFTS for Windows with MSYS2 mingw64 it seems it does not affect GNU/Linux to be confirmed
I have fixed that issue it was an issue to compute the next highest power of 2 see https://github.com/azonenberg/scopehal/pulls
So now all crash related to ffts are fixed it was impacting following scopehal classes:

• JitterSpectrumFilter
• FFTFilter
• DeEmbedFilter
• TestWaveformSource (used in demo mode)
