Please update dependencies: libjpeg doesn't exist no more, it was just replaced with libjpeg-turbo

Needs following after current libjpeg-turbo update.

I've installed Xsane via xsane-git tarball and makepkg -si
Xsane seems be installed, but:
1. There is not icon for Xsane in LXQt menu;
2. There is not .desktop file for Xsane in /usr/share/applications;
3. Launching Xsane from Qterminal brings up Xsane, scan for devices correctly and shows main window and Preview window by default, and using the Xsane's menu launchs Histogram, Batch scan and Advanced options windows as expected.
4. The worst things: Trying to scan or acquire preview do NOT work. in Qterminal shows:
[xsane] ERROR: xsane-startimage not found. Looks like xsane is not installed correct.
[xsane] ERROR: xsane-startimage not found. Looks like xsane is not installed correct.
[xsane] ERROR: xsane-startimage not found. Looks like xsane is not installed correct.
5. Looking as root for xsane-startimage link, binary or internal link using find command, there is not results.
6. Looking in /usr/bin/, there is two executables:
-rwxr-xr-x 1 root root 749136 mar 14 15:45 xsane
-rwxr-xr-x 1 root root 749040 mar 14 15:45 xsane-gimp

Please, could you tell me what are the causes of these malfunctions?
Your help will be appreciated.

Best regards, DanielH

gimp 3.1 still looks in /usr/lib/gimp/3.0/plug-ins

I needed to fix the actual plugin subdir.

xsane plugin is not showing up in gimp 3.x. Please update installation of gimp 3.0 plugin in the prepare() method:

Gimp 3.0 expects each plugin to reside in a subfolder in /usr/lib/3.0/plugins:

prepare() {
  ...
  mkdir -p "$pkgdir/usr/lib/gimp/3.0/plug-ins/xsane"
  ln -sf /usr/bin/xsane-gimp "$pkgdir"/usr/lib/gimp/3.0/plug-ins/xsane/xsane
}

gimptool --gimplugindir can be used to determine the plugin directory for the installed version of GIMP, however I'm not sure how it can be used at run-time to create the required symbolic link, since the post_install script of a package is "run chrooted inside the pacman install directory" according to https://wiki.archlinux.org/title/PKGBUILD

/usr/lib/gimp/3.0/plug-ins not detected in Gimp 3.1 (git version)

Much thanks, @timothy.lee. I've just updated the pkgbuild.

Latest git switched to GTK3, and supports both GIMP 2.x and 3.x.

Here is an updated PKGBUILD file:

  ## Link the plugin binary to gimp plug-in directories
  mkdir -p "$pkgdir/usr/lib/gimp/2.0/plug-ins"
  ln -sf /usr/bin/xsane-gimp "$pkgdir"/usr/lib/gimp/2.0/plug-ins/xsane
  mkdir -p "$pkgdir/usr/lib/gimp/3.0/plug-ins"
  ln -sf /usr/bin/xsane-gimp "$pkgdir"/usr/lib/gimp/3.0/plug-ins/xsane
}

For gimp 3.0 to recognize the xsane-gimp plugin it must be placed in the folder /usr/lib/gimp/3.0/plugins/xsane/

like this:

install -D -m755 src/xsane-gimp "$pkgdir/usr/lib/gimp/3.0/plug-ins/xsane/xsane"
