Dear Jonas, TL;DR:
The following list of packages allows to build Monero under sid: build-essential cmake pkg-config libboost-all-dev libssl-dev libzmq3-dev libunbound-dev libsodium-dev libunwind8-dev liblzma-dev libreadline6-dev libldns-dev libexpat1-dev libpgm-dev libhidapi-dev libusb-1.0-0-dev libprotobuf-dev protobuf-compiler libudev-dev Longer explanation: I have been experimenting with sid, using Docker (see attachement) and I was able to reproduce the problem, by simulating the list of dependencies, that occur in your build log (line 8 of the attached Dockerfile). The problem appears to be, that the Debian's dependency list is missing some of the boost libraries, needed to build Monero. The list above (and the only uncommented one in the Dockerfile) is the default, officially documented list. This list is being used in the Monero CI and it should serve as a pragmatic solution for you for the time being. What I didn't have time to do, is to bisect the individual packages, in order to find the root cause of the problem, which might turn out to be simply a packaging problem. I was looking for the optional_io.hpp file, mentioned in the error log, and it does appear to be available in the default [libboost1.74-dev](https://packages.debian.org/sid/libboost1.74-dev): https://packages.debian.org/search?suite=sid&arch=amd64&mode=path&searchon=contents&keywords=optional_io.hpp ... so I got not more clues unfortunately. In order to use the Dockerfile properly, please put it into the monero root source tree and run from the same directory: sudo docker build -t monero . I hope it helps. MJ Monero dev
