Huh, didn't expect anyone would actually need a 32bit linux version, but OK I think I'll provide one in the future, just in case.

These commands work correctly:
apt update && apt install libboost-all-dev libdb++-dev libminiupnpc-dev git make build-essential g++ libssl1.0-dev -y && git clone https://github.com/zettel-kasten/zettelkasten.git && cd zettelkasten/src && chmod +x leveldb/build_detect_platform
This command issues:
make -j 4 -f makefile.unix
Output file: zettel_out.txtHow to build the right demon?
