I like this piece of software and I use to catalog my ebooks. It’s mature enough that the last versions don’t add anything useful to me. Therefore I installed the official Arch repositories version which surprisingly is almost one year old, but takes less space and has fewer dependencies.

Sorry @alllexx88. Just saw this comment after the flag...

@jessidhia This would work for packages that just need calibre executable binaries. However, with plugins it wouldn't, since calibre-bin doesn't look into /usr/lib/calibre/calibre (or /usr/share/calibre/system-plugins or anything in /usr) for plugins -- it uses /opt/calibre/plugins for system-wide plugins instead. Hence, any plugin you install in /usr/... just won't be discovered.

This probably should have provides=("${pkgname%-bin}=$pkgver") to satisfy calibre dependencies in other calibre-related AUR packages like plugins and drivers.

@alllexx88 9.3.1-4 worked perfectly for me, thank you!

@INeedTogepi thanks for the report. After building in a clean chroot, I discovered that a bunch of dependencies is missing. They're pretty common ones, so I haven't discovered it before. Please try again with 9.3.1-4

I get the following error on the latest PKGBUILD:

EDIT: I apologize for posting this twice. The lack of word-wrapping made me think I posted the wrong error code, since I tried building once in a clean chroot, and then retried building again in the same chroot. Turns out the errors were identical... 🤦‍♀️

@un_pogaz reproduced it and pushed a similar fix, thanks :) figured it out right before your last clarification

@alllexx88 Oh right, my bad for the url. I was fooled by the text name, but the real url behind is good, on the github release, their is a second source archive that also use the basename calibre-9.3.1.tar.gz. (and this one is not stable to use)

And yes, I tryed the PKGBUILD, and it not work for me. You need to define the env variable before run calibre-debug, at the same time than QT_QPA_PLATFORM and CALIBRE_SRC, not in the "python script" because is too late: calibre-debug already load the translated string, and overide them here do nothing.

At least, is more consisten for me.
