gtk stack broken on Windows with most recent conda-forge packages

[ryanvolz]

Hello @ryanvolz,
I am facing the same error as @jmillo above.
I'm on Windows 11 Pro 22H2 (Build 22621.755)
Using the Radioconda 2022.09.22 Installer.

While executing the commands in the Notepad (in the screenshot 1 above) inside the Conda Prompt, in that specific order, this error message pops up.

Later on, when running the gnuradio-companion command (screenshot 2), the same error as the message above shows up again, then the Conda Prompt complains from missing (gtk-3-vs15.dll) and (atk-1.0-0.dll).

I'm willing to test it further if you can any suggest solution.

The problem was introduced somewhere in this set of changed packages:

glib is the problem, downgrading to 2.74.0 fixes things for me:

Yes this definitely seems to solve the problem.
I just used the following line:
conda create -n radioconda -c conda-forge -c ryanvolz --only-deps radioconda

Thanks for your prompt reply.

[AWADALLA333]

Yes. It works now.
I confirm that downgrading glib to 2.74.0 fixes this issue.

Documenting the temporary [until the broken gtk lib is fixed on Win11] fix I followed for whoever googling this issue later:

I ran these commands in a fresh (Radioconda 2022.09.22 Installer) Conda Promt:

1. conda create -n radioconda -c conda-forge -c ryanvolz --only-deps radioconda

2. conda create -n gnuradio

3. Then downgrading glib (3 packages [glib, glib-tools, libglib] will be downgraded 'together' through this command):
   conda install libglib=2.74.0

4. Then proceeded to "pin" (disabling the update of glib packages to the recent version 2.74.1 ), following this guide: ( https://docs.conda.io/projects/conda/en/latest/user-guide/tasks/manage-pkgs.html#preventing-packages-from-updating-pinning )
   a. Create an extension-less file named (pinned) in the folder: C:\Users\<USER_PROFILE>\radioconda\envs\gnuradio\conda-meta
   b. Edit the file (pinned) using Notepad.
   c. Add these lines:

glib=2.74.0
glib-tools=2.74.0
libglib=2.74.0

          d. Save and proceed.

5. Installing and running gnuradio in the set environment:

conda install gnuradio
conda activate gnuradio
gnuradio-companion

It should work now.
Many thanks @jmillo 😉
Much appreciated @ryanvolz 😃

Hi to all,
I goofed in my comment the following line does it in a single stroke (I copied the wrong one):
conda create -n radioconda -c conda-forge -c ryanvolz --only-deps libglib=2.74.0 radioconda
Regards

[ryanvolz]

This should be fixed now after conda-forge/atk-feedstock#21 and an upgrade of the atk and atk-1.0 packages to the latest versions, which allows using the latest glib 2.74.1 packages. Let me know if that's not the case.
