Arch user here. I’m trying to build zcashd as a user from my home directory.
checking for boostlib >= 1.20.0... yes
checking whether the Boost::System library is available... yes
checking for exit in -lboost_system-mt... no
configure: error: Could not link against boost_system-mt
I must have mistyped when I searched for the package and that’s why I tried to build from source. After seeking help from other Arch users, I realized that it’s in the communty repo, so it installed correctly from there.
