Building on Windows (be it directly, msys2, or cygwin) is tricky. We need to document it better but that bug is tracked in #165

[fhoshino]

Is there instructions for building on msys2?
I had libsodium installed already

➜ ~ pacman -Ss sodium
mingw32/mingw-w64-i686-libsodium 1.0.11-1 [installed]
P(ortable|ackageable) NaCl-based crypto library (mingw-w64)
mingw64/mingw-w64-x86_64-libsodium 1.0.11-1 [installed]
P(ortable|ackageable) NaCl-based crypto library (mingw-w64)

[reaperhulk]

Nope. It should be possible, but you'll need to set include and library paths properly for your env. I don't know anything about msys2 so I can't help.
