If you have a problem with Epson Scan 2, check if you need to install another backend for your scanner. More information on the Arch Linux wiki:

@datame and @TheKingofRavens, I've adjusted PKGBUILD with your suggestions. Thank you!

To remove the boost references a little easier, you can download manually, run makepkg, let it fail, then edit the files. This AI made sh script will help.

    # Clean up any empty add_definitions() that might be left

    echo "Warning: Some references might remain. Check the output above."
else
    echo "Success: All references have been removed!"
fi

After, use makepkg -si --noextract to install without undoing your work.

The package build fine with newer boost versions if one removes all the BOOST_NO_CXX11_RVALUE_REFERENCES=1 compiler flags. It is a little bit painful since it is defined in so many places, but afterwards it builds just fine.

Yes, I also cannot build this. It says we need to use boost 1.86. Well, boost1.86 is now an AUR package. I have changed the makedepends from boost to boost1.86 and i have added a line to the build command that tells cmake that the root of boost is/opt/boost1.86. It does detect boost1.86. However, i am still unable to build, getting this error:

fatal error: boost/format.hpp: No such file or directory
   38 | #include <boost/format.hpp>

I don't understand, because format.hpp IS located in /opt/include/boost directory. If anybody knows how to fix, I would be grateful.

It seems this package does not seem to install with latest version of boost. I had to downgrade to boost-1.86 and boost-libs-186 to able to install this.

/usr/include/boost/none_t.hpp:24:2: error: #error "Boost.Optional requires some C++11 features since version 1.87. If you have an older C++ version use Boost.Optional version 1.86 or earlier." 24 | #error "Boost.Optional requires some C++11 features since version 1.87. If you have an older C++ version use Boost.Optional version 1.86 or earlier." | ^

If V370 Photo is connected, the application crashes while constructing device selection dialog with std::logic_error, because it attempts to construct std::string from a NULL pointer.

Edit: got over it with the patch, but it still doesn't work. Probably connection string must be fixed as well, not only the display string.

I hope you get it up and running.

I just ran into the same issue. I think @tecnotercio's change for the inclusion of an outdated zlib didn't add back in links to the system HaruPDF after deleting links to the included one. So, I took out the part of the PKGBUILD that deletes HaruPDF from one of the CMake files, recompiled it, installed it, and got my scanner to save just fine. It seems to be compatible with the system zlib.

This might be a reasonable hotfix for anyone that needs it, but I have a hunch that this didn't actually link the system's HaruPDF instead of the included version.

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.
