Failure at Pre-Processing - Error msg "format specifier doesn't match argument type"

[Peter “DeepFrequency” Zabriskie]

Hi Folks, I am trying to use Hugin on an Ubuntu Studio 24.04 / KDE Wayland OS. It is a pre-installed app. It appears to work extremely well and correctly up to the point of Pre-Processing. Where I get this error msg. See Screenshot.

I have been trying to read and troubleshoot this to no avail. I did per FAQ and the Temporary Files limitations open Hugin with the command listed.
```TMPDIR=/media/disk-2/tmp hugin &```

This command did indeed open Hugin. But returned a very long Warnings/Critical list.if there are any Admin or developers who can help. Please RSVP. 
I post the return here:

```peterzabriskie@*******-MS-7D98:~$ TMPDIR=/media/disk-2/tmp hugin &

Most of the output is just wxgtk complaining, the only error is this:

ERROR: 23:20:55.514402 (./src/hugin1/hugin/huginApp.cpp:479) OnInit(): Tempdir could not be created: /media/disk-2/tmp

ERROR: 23:20:55.514430 (./src/hugin1/hugin/huginApp.cpp:483) OnInit(): could not change to temp. dir: /media/disk-2/tmp

..which suggests this path doesn't exist or can't be created.

What this the result of:

    mkdir -p /media/disk-2/tmp

Thank you for taking time to look into this with me. 

Why can't I get past the Pre-Processing step in Hugin without getting this message?

And I don't understand this part.

What this the result of:

    mkdir -p /media/disk-2/tmp

This looks like a command to make a temporary directory.

Is that what you are suggesting I do?

What I do not understand is why this program that came built in Ubuntu Studio is giving me this "assertion failed" error message that is in the screenshot. Which is why I tried opening the program with the recommended TEMPDIR=/media/disk-2temp hugin &

Which also failed to operate past the Pre-Processing step.

Is the fix for this "assertion fail" to make a temp dir?

Thanks again for your time.  --Pete

[Bruno Postle]

Sorry, this is an autocomplete mistake. I was suggesting that you ran the command to see what happens.

The only reason you would start Hugin like this is if you have a special disk (such as a usb stick) where you want to put temporary files: 

     TEMPDIR=/media/disk-2/temp hugin &

If this 'disk-2' doesn't exist then Hugin won't work.

Your computer should already have a suitable place for temporary files, Hugin will use that automatically, so just start Hugin by typing the name of the program:

    hugin

(you don't need the '&', this is just a complication, but feel free to ask)

OK so ignoring the TMPDIR=/media/disk-2/tmp hugin &  ....I start Hugin from my list of apps in Ubuntu Studio "Hugin Panorama Creator"

WHY am I getting this response at the Pre-Processing stage??? I can not get past this to produce a panorama.

I don't know why you are getting this error, possibly this is an ubuntu packaging problem.

Does it work if you open a terminal and start hugin by typing 'hugin' and nothing else? Any error messages should be more readable in the terminal.
