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:

https://wiki.archlinux.org/title/SANE/Scanner-specific_problems#Epson

@jan666 You can try loading my patch at https://build.opensuse.org/projects/home:Psheng/packages/epsonscan2/files/0005-Fix-crash-no-serial-number.patch and then rebuild. This should solve the problem.

Compiling went well but if i start epsonscan2 it terminates immediately with this error:

terminate called after throwing an instance of 'std::logic_error' what(): basic_string: construction from null is not valid

So not usable

CMake has had a major version change and old cmake scripts aren't working and need to be updated.

Error during installation. When I try to install the application, it fails and I get the following error message:

Update the VERSION argument <min> value. Or, use the <min>...<max> syntax to tell CMake that the project requires at least <min> but has been updated to work with policies introduced by <max> or earlier.

Or, add -DCMAKE_POLICY_VERSION_MINIMUM=3.5 to try configuring anyway.

@ElNick You can try my patch. https://build.opensuse.org/projects/home:Psheng/packages/epsonscan2/files/0005-Fix-crash-no-serial-number.patch

@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.

#!/bin/bash

    sed -i 's/add_definitions(-DBOOST_NO_CXX11_RVALUE_REFERENCES=1)//g' "$file"
    sed -i 's/add_definitions(\(.*\)-DBOOST_NO_CXX11_RVALUE_REFERENCES=1\(.*\))/add_definitions(\1\2)/g' "$file"
    # Clean up any empty add_definitions() that might be left
    sed -i 's/add_definitions()//g' "$file"
    # Clean up any double spaces or empty lines
    sed -i 's/  / /g' "$file"
    sed -i '/^$/d' "$file"

    found_references=1
fi

if [ $found_references -eq 1 ]; then
    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.
