Can not resolve symbols for libcamlrun.a(floats_b.o)

When I try to install ocaml-windows which wants to install ocaml-windows32 on my Ubuntu 16.04, I got all the time this error:

I don't know how to go further then. May be I missing something? I followed the README.md, note that I tried with 4.08.0+32bit and 4.08.0.

Are you perhaps missing a Windows system library? That would explain why `__configthreadlocale` is undefined.

Are you perhaps missing a Windows system library?

I installed all mingw stuffs, but I don't know how to get the "Windows system library" on my Ubuntu.

HAve you tried googling the undefined symbol to figure out which library provides it and see whether a cross-version exists for that library?

Hi all! The docker images we are using for the tests are based on debian distributions. Their dockerfile should provide a step-by-step example of how to install mxe. They all use this shared file: https://github.com/dockcross/dockcross/blob/master/common.windows

Then, this dockerfile provides all the step that we do on our end: https://github.com/ocaml-cross/opam-cross-windows/blob/master/tests/Dockerfile.base
