Added a patch to make it build again

This is the new prepare() function which make xsane to build again:

prepare() {
  cd "$srcdir/$pkgname-$pkgver"
  # fix use "xdg-open" instead of "netscape" to launch help browser - taken from Fedora
  patch -Np1 -i "${srcdir}/xsane-0.995-xdg-open.patch"

  patch -Np1 -i "${srcdir}/0001-lcms2_configure.patch"
  patch -p1 -i ../xsane-preview-selection.patch # Fix selection preview
  patch -p1 -i "${srcdir}/configure-add-stdlib-to-conftest.patch" # Fix failing build of conftest by adding stdlib.h to test program

Neither xsane nor xsane-git built for me. I checked out from git and got it to build with autoreconf --install --force ./configure make (sudo make install)

It needs libxml2-legacy to run, though.

Maybe you can somehow integrate that to the pkgbuild.

didn't compile (same issues as @maderlos) had to resort to xsane-git

@maderios regardless if the old gtk2 version is no longer being maintained, this should still be able to be built, so the package maintainer here has to either make some patches to make it build or delete the package.

As it stands, this cannot build in a clean CHROOT, so the package maintainer should be making changes to the PKGBUILD or adding patches

@moormaster Old gtk2 xsane is no more maintained by devs. They're working on future gtk3 version

@sowieso It builds for me. Anyway, gtk2 is going to be dropped upstream. Look here
https://gitlab.com/sane-project/frontend/xsane/-/issues/66

For me it complained about gcc, patch, and make not being installed, maybe add it as build-dependency. In the end it failed with

ERROR: GTK-1.2.0 or newer is needed for compiling xsane
       if you installed gtk as rpm make sure you also included
       gtk-devel

though.

xsane-gimp doesn't build/work with Gimp 3.0, it's upstream issue, xsane-gimp project is outdated, no more maintained. I think that's why it was removed from official repo.
