depixelization/source/utility/public/FileUtil.h:49:21: error: 'transform_reduce' is not a member of 'std'

[onefish51]

I run the code on Ubuntu 18.04 , cmake version 3.18.2, boost 1.72.0, GCC 8.2.0.

when I run cmake --build .

Like the Title, it throw me a Error message:

depixelization/source/utility/public/FileUtil.h:49:21: error: 'transform_reduce' is not a member of 'std' return std::transform_reduce(std::cbegin(value), std::cend(value), std::string{}, std::plus<std::string>{},

and

depixelization/source/utility/public/FileUtil.h:59:25: error: no match for 'operator==' (operand types are 'const std::__cxx11::basic_string<char>' and 'void') return item == toLower(filePath.extension().string());
thank you very much!

Hello!

Apologies for such a late response here. It seems that GCC 8.2 doesn't support std::transform_reduce. The earliest version I could find, via godbolt.org, is GCC 9.3.

See: https://godbolt.org/z/8doxrfjor.

Thank you for bringing this to my attention!
