vips: unknown action "dzsave", vips-8.15.1 on Gentoo

[jbhanks]

Bug report

Describe the bug
I built vips on Gentoo with the USE flags archive graphicsmagick heif imagemagick imagequant webp jpeg2k jpegxl python

When I try to run vips dzsave, I get vips: unknown action "dzsave".

From researching a bit, I know there was an issue with libgsf license incompatibility, but I thought that was supposed to be solved?

To Reproduce
Build media-libs/vips-8.15.1 on Gentoo with USE flags archive graphicsmagick heif imagemagick imagequant webp jpeg2k jpegxl python

Expected behavior
Ability to run vips dzsave command

Actual behavior
unknown action

Environment
(please complete the following information)

• OS: Gentoo Linux with kernel 6.1.66
• Vips: 8.15.1

Hello @jbhanks, dzsave needs libarchive. I see you've added that to your USE flags, but it looks like it hasn't been detected by libvips for some reason.

I would check the build logs. At the end of libvips configure you should see a table like:

vips 8.16.0

Hey, thanks for the quick reply. I just deselected and re-emerged vips (again), and all of a sudden I do have dzsave!
In between when I posted and you replied, I switched my kernel to 6.6.16 🤷 . I any case, it seems to be working now. I also did have to dig around a bit to figure out to use the archive flag, can you think of any reason why the Gentoo repos might not have enabled it by default?
