Re: Displaycal and python 3.14

What command produced the output:

It's from the instructions here: https://github.com/eoyilmaz/displaycal- … s_linux.md

Here's the whole output  including the command:

Re: Displaycal and python 3.14

@seth looks to be an upstream issue in audio.py?  sdl is selected if libSDL_mixer-1.2.so.0 is found. sdl the python module is only imported if typing.TYPE_CHECKING is TRUE so https://github.com/eoyilmaz/displaycal- … io.py#L601 is referencing sdl that has not been imported.
Edit:
https://github.com/eoyilmaz/displaycal- … io.py#L305 would create globals pyglet, pyo, sdl, wx but those variables are not used so has no effect.  https://github.com/eoyilmaz/displaycal- … io.py#L150 use of global wx and function does try and import wx.  pyo and pyglet follow the same pattern while sdl/sdl2 init functions are missing the try import and sdl instead references the shared object but that value is not returned or made global.  58af90b Fixed all linting errors in DisplayCAL.audio module. which introduced the sdl/sdl2 imports is confusing sdl the python module and sdl the shared object and I suspect the linter only allowed it because None is listed as a valid type in all the cases along with sdl.Mixer and sdl2.Mixer.

Re: Displaycal and python 3.14

sdl/sdl2 init functions are missing the try import

What seems like an obvious bug but wasn't introduced w/ that patch. The older code also prefers SDL and only runs dlopen on some hardcoded objects

@glenjo, does any of the older (not development) versions (python 3.14 or 3.13) use SDL audio?

The old code before https://github.com/eoyilmaz/displaycal- … a83d489ea5 worked because it had global sdl in the same function that set sdl = dll after the lint refactor global sdl did not follow sdl = dll to the new _load_audio_dll function. The assignment only being local produces `NameError: name 'sdl' is not defined`.

Edit:
glenjo if you do

cd displaycal-py3/
git checkout 1843da096bcb3a4ec869c737c6f054299810b054 # the parent of 58af90bd8d6527603274e53eadccefa83d489ea5
make venv build install

Can you still reproduce the issue?

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false

HEAD is now at 1843da09 [#552] Fixed `DisplayCAL.wx_windows.ProgressDialog.anim_fadein()` to to call the `AnimatedBitmap.SetBitmaps()` with the `range_` argument instead of the `range` as it is recently renamed.

Re: Displaycal and python 3.14

Re-building with python 3.13...

It built, and launched OK, running a calibration which takes a bit.

Got to the same point where displaycal 3.9.17-4 failed, but had a different error:

Looks like it got further along in calculating the icc file. Here's the whole output:

Note: switching to '1843da096bcb3a4ec869c737c6f054299810b054'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false

HEAD is now at 1843da09 [#552] Fixed `DisplayCAL.wx_windows.ProgressDialog.anim_fadein()` to to call the `AnimatedBitmap.SetBitmaps()` with the `range_` argument instead of the `range` as it is recently renamed.

Re: Displaycal and python 3.14

That proves which commit introduced the sdl regression. Switch back to HEAD of the main branch. Change line 186 of DisplayCAL/audio.py from

    global _SERVER, _LIB, _LIB_VERSION, _INITIALIZED,

to

    global _SERVER, _LIB, _LIB_VERSION, _INITIALIZED, sdl

Hopefully fixing the `NameError: name 'sdl' is not defined` error.

So much for a one line fix.  As a workaround undo that change and change line 120 to:

            libs = ("wx")

Built OK, starts up OK, running a calibration, and success!

Hey, thanks!  Going to run some under with KDE Plasma Wayland and see how things work out. This test was under XFCE X11.

Re: Displaycal and python 3.14

Try to change #292 to "global _SERVER, sdl" instead - technically would have to be applied to all routines.

Also needs to break out of the loop when _SERVER is set to prevent overwriting a successful init.  Additionally it updates the typing and removes and duplicate pyglet check. Note changed the unused global use.

Re: Displaycal and python 3.14

Yes, there still some issues there, but no sound is not a deal killer for me right now. I suppose if I was doing many more calibrations having sound would start to be a pretty useful feature.

What's more interesting is that I was able to successfully make an ICC profile while running KDE Wayland, but if I actually apply that profile, the monitor is very dark, almost black. If I apply the ICC profile I made for XFCE X11 in KDE Wayland that profile too is also very dark (it works fine in XFCE X11). Now that I do some searching, I see this has been reported before for KDE Wayland. On this system X11 is running at 8 bpc, but Wayland is running at 10 bpc, and I can even use HDR.  The monitor is a BenQ SW270C which is HDR capable, it's a limited HDR compared to newer HDR monitors. But right now in Wayland and Wayland HDR, the colors are a little off so I don't use it for photography work in Wayland yet.

I'll report what I found over in the KDE forums.

And again, thanks!
