Errors building latest hugin default source

[Terry Duell]

Hello All,
I've just attempted to do an rpmbuild of the current default source
(06c12feee548 8336 default) on Fedora 33, using my normal build methods which
have been working OK of late.
Attached is a partial listing of the rpmbuild output showing the initial error
messages.
Has anyone else had similar problems?
I thought it best to check prior to lodging a bug report, as it may be (often is
😊️) an issue at my end.

Cheers,

This is a bug in wxWidgets, which is already fixed: https://github.com/wxWidgets/wxWidgets/commit/b4aaa1003247535675f21b69cf800353012ca81c

I pushed a workaround to the repository.

Thank you Thomas.
It builds OK now.

Color profiles "I will not pass" - it seems to be a cardinal error. Now not only in .jpg, it also appears in .tif images.
All these color profiles were developed in the times of CRT monitors and early digital cameras, that had problems with displaying proper colours, especially blue tones.
Today all images can be stitched, taking no care for the profiles, just ignoring them.
There is no difference if we disable color management in the monitors, graphic cards and applications. We see the real colors as the camera registered them.

Hugin may display a warning and continue to work ignoring these profiles.
The simplest way will be to disable profile detection when loading images (activate the warning at user`s request and risk).

The version above added undesired yellow tint on the wall
The version below looks as it looks in real world, and the details are better visible.

   Hi Abrimaal,

   Just to tell that I use a color calibrated monitor, and also have calibrated a few other monitors (none of them CTRs), and I know by experience that color management and color profiles do make a big difference!

   Some pointers: hardware like the Datacolor Spyder5EXPRESS, and software as DisplayCAL and ArgyllCMS. Even my former (satellite) TV provider offered, as a paid service, the color calibration of digital TV sets.

   And now I have found some links which I will see myself in order to better understand all this :)

A missing DSO normally indicates that the order of the file names in the linker's command line is wrong...

Hi Luís Henrique,

It is possible in Hugin to merge (overlay, collage) various image formats (jpg, png, tif...), various sizes and even various origins (digital photo + scanned negative + screenshot + rendered graphics).
It seems almost impossible to hear, like adding centimeters to inches, euros to dollars, water to oil... and this is possible in Hugin.
Color spaces / profiles are just special effects, like adding milimeters to kilometers, seconds to days. These milimeters change statistics, but are invisible for someone who runs long distance (long time) projects.

I consider this as the main error in the program, that there is no ignore button when opening (or ignore color profiles option in settings).
Image editing software often apply color profiles without asking. Even the developers are not aware of this, when using ready libraries.
It refers mainly to mobile apps, but not only. I use Machinery HDR Editor for improving image quality. It applies an exotic "Black scaled" color profile, without asking.
Images processed (protected?) this way cannot be merged with other images in Hugin.
The original photo + processed photo cannot be opened by Hugin for selective blending of both.
More... even when two editors are using different versions of the same color profile, Hugin GUI does not allow to open them.
More... even when the version number in one image is 2.1 and in another image is 2_1 they cannot be opened.
This is like adding lightyears to milimeters (converting thousands of images, video frames and screenshots may take longer than blending them).

And the second place is (the main error no 2):
After "Image was not found, please manually select the correct image" and pressing Cancel or [X]
the project is closed automatically.
The missing image was deleted years ago, because of low quality.
I need to open the project with all remaining images.
After deleting the line in a text editor, that refers to the missing image, Hugin opens the project and everything is working. :)
