Qpdfview update failing on poppler-qt6 development

As Subject:

Project ERROR: poppler-qt6 development package not found
make: *** [Makefile:48: sub-pdf-plugin-pro-make_first-ordered] Error 3
==> ERROR: A failure occurred in build().

poppler qt5 and qt6 are installed and I re-installed poppler-qt6. There is no dev package.

qpdfview is an AUR package. I guess that you must be on the unstable branch to build it.
(It works for me.)

Ah! Hadn’t noticed the AUR bit. Thank you.

That probably explains another similar recent case for xnviewmp.
