I'm getting an error when scanning to pdf. epsonscan2: symbol lookup error: /usr/lib/epsonscan2/libepsonscan2.so: undefined symbol: HPDF_New

UPD: I have libharu installed, but epsonscan2 is not linked to it.

@Xyphon and @torben: I've changed the PKGBUILD so that the HaruPDF and ZLIB libraries don't compile together with Epson Scan 2.

@jazzi: I've included armv7h architecture in the package.

epsonscan2 is not available for the 'armv7h' architecture

On the Epson download page there is also ARM Raspbian package available, is there a way to support armv7h?

I can confirm Xyphon's observations. Apparently, epsonscan2 comes with a prebundled, outdated version of zlib, which does not compile on arch anymore:

(Sorry for the German, but it should explain itself)

getting the following errors when installing from the AUR:

No luck using this with an Epson Perfection V600 Photo. The app won't launch even though it initially detects the scanner. Installing all the backends (separately and then together) didn't make a difference.

I did have some luck with using "Image Scan! for Linux" from AUR though. It's not as good as Epson's app, but it's much better than nothing. Specifically I installed the following packages:

iscan 2.30.4.2-3

iscan-data 1.39.2.1-1

iscan-plugin-gt-x820 2.2.1-2

Just one note.

The package requires gcc to build, it fails with clang 16.0.6.

Few months ago everything working fine. But now epsoscan2 can't detect my L350 from USB.

I tried using imagescan. After tweaking utsushi.conf, I can finally scan my document.

I think I will use simple-scan because it doesn't need any configuration.

Version 6.7.0.0 crashes lately for me. I changed locally the PKGBUILD file to version 6.7.42.0, updated SHAs and the new version does not crash for me.
