Do you know how to fix this or should I investigate?

ImageMagick API has changed in 6.9.10. Looks like chafa needs to be updated to work with the new API.

That's clear. I was asking whether you know how to fix it (e.g. if you are familiar with the new API).

Unfortunately I cannot find any API documentation on the change. The ChangeLog is not comprehensive.

Code repo: https://github.com/ImageMagick/ImageMagick6
IM6 website: https://legacy.imagemagick.org/script/index.php

I took a quick look at the code snippet you posted. The function call has not changed in IM6, but the configure tests in chafa are failing.

checking for 5-arg MagickResizeImage... no
checking for MagickAutoOrientImage... no

Previous builds had these passing:

checking for 5-arg MagickResizeImage... yes
checking for MagickAutoOrientImage... yes

If the configure tests are fixed the build should work.

Have you tried with Chafa version 1.0.1? It has several build fixes (specifically fixes for ImageMagick detection) relative to 0.9.0, which seems to be the failing version.

Thanks. It works.
